Re: [Rosegarden-user] Audio File Location Issue

2022-01-28 Thread steve conrad
my personal preference is to default to the same ./ as the rg file itself.

That way anyone in the habit of dumping all their rg files into
~/rosegarden will know where to find them, while people who want to save
them somewhere else can effortlessly keep the associated audio files in
that different location.

Anywhere relative to the *.rg file is good from my point of view, but this
option seems likely to be the least coding

Introducing a new dialog for something that most people haven't had spend
any time thinking about so far seems like an undesirable increase in user
friction. Not quite kwallet kind of nuisance, but better off avoided in my
opinion.

Re: [Rosegarden-user] Import sf2

2021-02-20 Thread steve conrad
Importing the sf2 in the 'manage midi devices' dialog has a mostly
decorative function. Ie, it only effects the the labels that RG assigns to
tracks.

If you are fairly new to this sort of stuff what i bet you want to do is to
load the font into a synth to make some sounds.

This is done in qsynth itself and the process is fairly self explanatory.

Once the sf2 is loaded in the synth, there is no urgent need to import it
into RG unless you find it overly confusing to have RG calling your presets
by the wrong name.

Re: [Rosegarden-user] [OT]: quick and easy music making: a marketer's dream [WAS] Re: beginners question : getting sound

2021-02-10 Thread steve conrad
Technically speaking RG does make sound without any coaxing although this
point likely won't be well taken by a first time user who just want to hear
some sequenced sounds.

Part of the problem is the sheer diversity of available instruments. Apart
from the go to fluidsynth, most distros have packages for aeolus, bristol,
hexter and plenty more. For only slightly more effort linuxsampler is just
a compile away. As such there is no single clear path to making notes come
out.

>From a novice's point of view, it will not be immediately obvious that just
hooking up RG to sytem out will be insufficient to hear the sounds they are
looking for.

To this end, it might be helpful to steer beginners toward using DSSI
plugins. That way, at least, connecting RG to system output (which should
happen automatically on startup) will make sound come out with a minimum of
configging around.

Users consulting the examples included with RG won't find a lot of help in
this regard. I know my own contributions in this area still reference a
SB128 sound card which wont get them very far in the right direction.
Perhaps a little sprucing up here would be helpful.

I haven't used RG in the fluidcentric way outlined in this thread for quite
a while now.

My current way of making the sounds come out is to use carla to connect RG
to sfz files. Apart from the sfzs themselves, everything I use ships stock
with UbuntuStudio.

My workflow is as follows:

1) Open studio controls. Make sure the a2j bridge is selected and start
jack.

2) Start carla. Drag and drop some sfzs From the file tree on the left onto
the main canvas and connect them to system out.

3) Fire up RG. Go to the 'manage midi devices' pop up and add a new device
for each sfz to be used, giving each a helpful name.

4) Back in carla, connect the RG instruments the their respective sfzs.

5) In RG, select the appropriate sfz instrument for each track rather than
just accepting the default GM device.

A similar approach works with sf2 files as well.

[Rosegarden-user] work flow irritants

2020-12-31 Thread steve conrad
I was recently working on an audio project in RG using an existing midi as
a guide track and encountered a couple of pesky issues I haven't run up
against before.

The midi I imported (understandably) didn't have any audio track, so I
added eight of them at one go via tracks->add tracks Doing so has the
unfortunate result that all of them come up as audio #1 rather than audio
#1-8 as might be expected and as is the case in a new empty file. As such,
they have no independent volume control and are all on the same effects
bus. A suboptimal arrangement.

While the solution was simply to manually change them to audio #1 through
audio #8,  it  didn't jump right out at me until after a bit of thinking,
never having come across this particular situation in my 15+ years of using
RG.

Is this a bug or a feature?

My second irritant is that it is no longer possible to copy and paste
between separate invocations of RG. I distinctly remember having done so in
the past. That is to say, if I have a part in one file that I wish to paste
into another, it won't do to open them both up in seperate invocations of
RG and copy and paste between them (as I have done at some point in the
distant past). The clipboard is not shared between the two instances of RG.

Instead, I have to open one file, copy the stuff I want, close that file
and open the other. Ok if it's just one copy and paste operation, but get
pretty darn tedious  if I want to transplant several chunks.

I struggle to imagine a context in which I would prefer the current
behaviour to the old one, but maybe there's a perfectly good reason for it
in someone's eyes.

Re: [Rosegarden-user] Rosegarden raspberry pi?

2020-12-13 Thread steve conrad
I have used Rosegarden on a Pi3. It worked about as much as any desktop app
can be said to work on one of those things. Didn't make it crash more than
anything else. As near as I can make out, once a Pi runs out of RAM it just
reboots and that happens pretty often using Raspbian.

PIs are basically pretty useless though. The price point is a bit of a
hoax. By the time you gear them up with a case, a screen and such they cost
as much as a low end laptop while offering a fraction of the performance
and stability.

If you want something small and quiet for rosegarden etc, try looking into
a micro PC like a Gigabyte brix. They've got a real computer inside.

I've had a Pi for a couple years now and while I have found it technically
capable of performing a variety of tasks, I have yet to find any
application for which it is the right tool. So I don't use it for anything
at all. A solution in search of a problem.

And of course they're offensively black boxed as you would expect from the
bastard child of a bunch of Broadcom engineers. Those things are not open
source friendly in any way.

Imho, Pis are a waste of time and money but Rosegarden doesn't present any
special problems as far as they are concerned.

I've heard some people like them more than I do.

Re: [Rosegarden-user] Humanizing MIDI tracks

2016-03-27 Thread Steve Conrad
Two good things to randomize are timing and velocity, obviously.

Note velocities can be tweeked in the velocity ruler to get a faux random 
effect.

The start time and duration of notes can be given individual micro-adjustments 
in the note properties pop up. Pushing the tempo or just plain screwing it up 
can easily be replicated in this manner.

Maybe more labour intensive than one would hope, but certainly enough to breath 
some life into the rendering.

Playing with the pitch ruler can also get some of the starch out of a midi 
sequence.--

Re: [Rosegarden-user] Bars & Ties

2015-02-11 Thread Steve Conrad
Csound is utterly indifferent to note names and accidentals. Notes are
called by their frequencies (yuck), midi note number or most commonly
PCH notation which is what Rosegarden exports. In PCH, octaves are
integers and the notes within an octave are decimals, so that 6.00 is
middle C, 7.04 is the E a tenth above middle C etc. 

In this scheme 4.24 is also middle C, by the way, so transposition by
simple addition (but not subtraction) is possible. Subtraction doesn't
work because 6.00 - 0.01 = 5.99, which is Eb eight octaves and a minor
third above middle C rather than the B just below it.

Re: [Rosegarden-user] Bars & Ties

2015-02-11 Thread Steve Conrad
Thanks. That's helpful.

Accessing bar line positions is more trouble than it's worth for me
right is what that part of your answer tells me. That frees up some time
for me.
 
As for the ties,  a note would have two properties: one for tied from
and another for tied to. Any idea where I could find that code? Just
looking quickly, I didn't see anything like that in event.* or
notationtypes.* and there doesn't seem be be a file called note anywhere
in the tree.

I'm expecting there to be an accessor method like note->getTieForward()
which returns the note to which a given note is tied but I can't find
one. Or maybe it's just note->getProperty('tiedForward') and I have to
find where the properties are defined. In either case, I can't find it.
But I'm hardly a well informed searcher.

Csound understands legato ties between notes of different pitch, but it
has no reason to use ties between notes of the same pitch because score
events don't take place in the context of a staff with bars and time
signatures. Notes just have arbitrary start times and durations. Very
economical if you take a second to think about it. 

Unfortunately, collapse all will only work for notes with durations that
divide by 1,2,3,4,6,7 or 8. (I'm assuming that collapse all remembers to
use double dots to get the sevens). That is to say a dotted quarter note
tied to a regular quarter note can't be collapsed into anything else.
Still, seven out of eight is pretty good, so I'll be using that in the
future when doing Csound exports. Thanks.

code, all non-note events are printed as a comment line, and bar lines
aren't there in the output.

Same thing for ties. They aren't there either. If they aren't an event,
what are they, and how do I enumerate them? I'm more than willing to
spend a bit of time reading the code if someone could point me in the
right direction.

I'm trying to add a commented mention of the bar numbers to the csound
export. Also trying to correct the way two tied notes are output as two
separate notes instead of one long one.

Not being familiar with the RG codebase, I'm running up against a bit of
a needle in a haystack problem though.

(Sent this once already, but from the wrong email. Sorry if it double
posts eventually).

Thanks. For now just commit the attached Csound Export.cpp. That really
improves usability from my point of view.

I'll try to figure out how to do something about the ties as time permits.

Re: [Rosegarden-user] CsoundExport

2015-02-01 Thread steve conrad
It mostly works as it is.

The thing is that you can't proceed on the assumption that your RG
composition will come popping out the other end of csound at the press
of a button. I use it to make a start on a csound score which then
needs some touching up by hand. However, just getting all notes down
in the right order is a huge headstart on the problem.

The other day I tried entering twelve bars worth of a 12/8 phrase into
a csound score manually, and it took most of the evening because I
kept miscounting the syncopated bits and had to keep fixing my
mistakes.

While most instruments are going to take more parameters than the
basic five, in general, the value will just be a "." in a human edited
score.

So, while RG isn't going to output a renderable .csd file any time
soon it is a very handy tool for generating the note lists.

For example, here's a chunk of an actual score I'm working on:

; p1p2  p3  p4  p5  p6  p7  p8  p9
; Inst  Start   Dur Amp Pitch   Press   BowPos  Vfreq   Vamp

i 1 0   1   40  6.003   0.135   0.01
i 1 +   .   32  6.072.5 .   .   .
i 1 +   .   34  7.032.0 .   .   .
i 1 +   .   28  6.001.5 .   .   .

Note how many of the values past p5 are just dots (repeat the value
from the line before). RG can generate output like the scrap below,
which means that if you wanted to play it with the wgbow instrument
for which the above scrap was written, you'd just have to go through
and tack on the bits after p5. I assure you that this is a huge help
to me. The below output was made using my modified CsoundExport.cpp
file, fyi. The stock version would have "i 0" in place of "i 1" and
would have p4 (Amp) and p5 (Pch) reversed.

;; Inst Start   Dur Amp Pch
;;  --- -   
;; Event type: clefchange
;; Event type: keychange
   i1   0   1   127 9.02
   i1   0   1   127 8.11
   i1   0   1   127 8.07
   i1   1   0.3 104 8.07
   i1   1   0.3 104 8.11
   i1   1   0.3 104 9.02
   i1   1.3 0.3 96  8.07
   i1   1.3 0.3 96  8.11
   i1   1.3 0.3 96  9.02
   i1   1.7 0.1896  8.07
   i1   1.7 0.1896  8.11
   i1   1.7 0.1896  9.02
   i1   2   0.6 124 8.07
   i1   2   0.6 124 8.11
   i1   2   0.6 124 9.04
   i1   3   0.6 119 8.07
   i1   3   0.6 119 8.11

(This is the first phrase of one of the tunes from The Nutcracker, btw).

Punching the notes into the notation editor is immensely quicker than
working out the note times in a text editor.

What RG can't do though is to help you with the orchestra files. Kind
of on your own with the documentation on that front. That said, the
folks at the csound mailing list are active and helpful.

The preferable solution would be to have a spreadsheet sort of editor
to which extra columns can be added to accomodate the extra p values.
Pretty sure Qt already has a spreadsheet library built in.

[Rosegarden-user] CsoundExport

2015-02-01 Thread steve conrad
Since rosegarden remains the only way I know of the create a csound
score using standard musical notation, I thought I might adjust a
couple of pesky things about the otherwise excellent way it makes the
files.

1) Instrument 0 is not valid in csound, so I just add 1 to the track
number to avoid i 0.

2) By convention, the first five parameters of a score are:

   p1 => Instrument
   p2 => Start
   p3 => Duration
   p4 => Amplitude
   p5 => Pitch

I've just rearranged the output to reflect this custom (assuming that
velocity is a reasonable standin for amplitude).

I've been running some conversions with this this afternoon and it
doesn't seem to break anything else in RG. Changing the RG source was
easier for me than writing a perl script to modify RG's output, even
though I'm definitely not anything like a C++ programmer.

There are a couple of other irritants I'd like to correct as well -
most notably the way two tied notes of the same pitch just come out as
two regular notes, which can be pretty jarring at times. But devising
a way of adding up the durations of two tied notes to output one long
one would require a bit more effort on my part.

For now this minor change greatly improves the usability of
CsoundExport, from my point of view at least.

Does anyone else actually use this?

Thanks Ted. That was just the information I needed. Went off without a hitch.
I also tried leaving the jack.pc file untouched and passing the
correct path to the jack headers as an environmental variable. This
also worked.

Kicking myself for checking that all the libs were where pkgconfig
said they were, but not bothering to check in on the header files.

Below is a scriptlet I used to run configure for me. Maybe someone
else will find it useful in a similar situation.

[Rosegarden-user] Ubuntustudio and Elusive libs

2015-01-31 Thread steve conrad
Having a bit of bother getting RG 14.12 to find libs when compiling
UbuntuStudio 14.10.

The problem, of course is that Ubuntu sticks its libs pretty deep in
the file system under /usr/lib/x86_64-linux-gnu/

When it can't see libQtGui.so I can easily solve the problem by
changing my configure command to:

$./configure --with-qtlibdir=/usr/lib/x86_64-linux-gnu/

The problem that's holding me up is that when it can't find the jack
libs, it isn't quite as chatty, so I don't really know what it isn't
finding:

configure: WARNING: Required JACK library not found, building with no audio!

The configure script doesn't have a --with-jacklibdir option so I
guess I'll have to set some sort of a jack related environmental
variable like JACK_CFLAGS  or JACK_LIBS but I'm not really sure how to
set them.

The output from pkg-config all seems pretty reasonable. There are in
fact libs where pkg-config says they ought to be:

steve@laprat:~/Downloads/rosegarden-14.12$ pkg-config --print-variables jack
exec_prefix
prefix
libdir
includedir
server_libs
steve@laprat:~/Downloads/rosegarden-14.12$ pkg-config
--variable=exec_prefix jack
/usr
steve@laprat:~/Downloads/rosegarden-14.12$ pkg-config --variable=libdir jack
/usr/lib/x86_64-linux-gnu
steve@laprat:~/Downloads/rosegarden-14.12$ pkg-config --variable=includedir jack
/usr/include
steve@laprat:~/Downloads/rosegarden-14.12$ pkg-config
--variable=serverlibs jack

I notice that some of the jack libs are put under a subfolder of
libdir, so maybe whatever it is that RG can't find is hiding in there:

steve@laprat:~/Downloads/rosegarden-14.12$ ls /usr/lib/x86_64-linux-gnu/*jack*
/usr/lib/x86_64-linux-gnu/libjacknet.so

[Rosegarden-user] Useless Mode?

2014-11-17 Thread steve conrad
After spending a fair amount of time punching in a piece today, I
suddenly found it would only play one track at a time. Whichever one I
select in the main window.

This strange and unhelpful situation only affects the tune in question
and seems incurable.

I'm wondering if I might have accidentally clicked on some 'useless

seem to find it again to unclick it.

Any suggestions would be much appreciated.

[Rosegarden-user] sooperlooper

2014-05-05 Thread steve conrad
Thanks for responding to such an arguably off topic question. After a
bit of tinkering around I have managed to figure things out, mostly.

I am trying to use Rosegarden to control SooperLooper in order to
automate a variety of tasks, thereby freeing my hands from the mouse
and putting them back on my guitar where they belong.

So far I have managed to assign midi binding to the more basic commands.

Pretty straight forward, really. Just go to SL's session->properties
dialog and select the MIDI Bindings tab. Assign events to notes and
then make an RG file containing these notes.

However, I am a bit stymied trying to set up a pitch_shift binding.

When I try to create such a binding in the midi binding tab of the
preferences dialog, I see the target range showing -12 to +12 as I
would expect, but I'm kind of confused by data range options.

Obviously 128 doesn't divide evenly by 25, so I'm guessing I should
limit the range to something that does - say from 88 to 112.

When I do this I get the following line in my .slb file:

0 n 74  set pitch_shift 0  -12 12  norm 88 112


But then where does the data come from? These control events show up
in RG as plain old notes. So the only "data" they're packing is the
velocity.

So I set up and RG file where the are a bunch of note 74 type events
and I give them velocities somewhere in the range of 88 to 112.
(Fortunately for me, 100 is the default velocity for a new note in RG,
which corresponds to a pitch_shift of 0).

Much to my surprise this almost works as expected. The only problem is
that as soon as the notes end, the pitch_shift reverts to the
unhelpful default of -12. This is easily corrected by changing the
event type from "note" to "note on" in the midi event panel at the
bottom right of the midi bindings tab. Why it defaults to -12 is a bit
puzzling though.

One minor glitch is that pitch shifting the loop to which SL is
synching will cause other loops to fail to trigger, so don't do that.

2014-05-02 Thread steve conrad
Has anyone tried using RG to control SooperLooper?

I notice RG quite readily attaches itself to SL in the studio setup,
but I'm just not smart enough to figure out how to get RG to send midi
control events to SL.

I've been playing around with loops on my guitar lately, but find it a
bit distracting to have to reach over and mess with the mouse while
I"m trying to play.

As far as I can tell, it should be possible to automate the recording,
overdubbing and manipulation of loops just by having an RG piece that
sends out command to SL. Just have no clue where to begin.

Re: [Rosegarden-user] Ubuntu Studio 14 - Don't Do It

2014-05-02 Thread steve conrad
Just recompiled the current version and no crash. Thanks.

Yes, I did mean to paste from the notation editor. Sorry I wasn't
clearer. Odd that the selection bug hadn't shown itself to me until
after upgrading the OS.

Bit of a chore getting everything to compile at first. Ubuntustudio
isn't all that developer ready.
Got a little frustrated trying to tell configure where to find things
at first, but the wiki info about how to compile from SVN was
extremely helpful and to the point.

The new version of the OS doesn't seem quite as awful as it did this
morning. Not sure what's up with that. Network stopped dropping the
connection and Firefox isn't freezing up all the time. And I didn't
have to recompile those things. VLC still freezes up the system when
playing video though. Guess I should have help off for a bug fix
release of ubuntustudio before taking the plunge. Live and learn.

[Rosegarden-user] Ubuntu Studio 14 - Don't Do It

2014-05-02 Thread steve conrad
I just "upgraded" from ubuntustudio 13 to version 14. Bad move.
Everything crashes all the time. Too bad, really. I've been using this
distro for a few years now, and this is the first time I've ended up
installing a truly regrettable dud.

Most relevantly to this list, RG dumps its core in response to simple
copy and paste operations making it pretty much unusable. Not sure if
this is because of a defective RG package, or just the general
instability of the OS. I've attached a small example that reliably
crashes RG on my machine. Just try to copy and paste the last two bars
into the next bit of empty space.

Here's what RG has to say up until the core dump:

#
#  RG Output   #
#

[notation]  NotationView::slotUpdateMenuStates: Have selection; it's
0x2e8d490  covering range from  61440  to  69120  ( 13  events)

[notation]  Do not have NoteRestInserter

[generic]  EventSelection::addRemoveEvent Sent event that can not be
found  in segment.  Exiting method
Segmentation fault (core dumped)


##
#  End RG Output #
##

Curious to see if anyone else can reproduce these results on a less
dodgey system.

Re: [Rosegarden-user] Setup Automatic Pitch Bend?

2013-04-16 Thread steve conrad
Probably the most efficient work around is to make your own sound font
with the samples retuned to suit your purposes.

The midi note to sample mapping of a font doesn't really require you
to sound the note corresponding to the midi note number you've
selected. Percussion fonts are one obvious example of a font where
note number doesn't correspond to midi pitch.

An hour or  two fiddling around with Swami and you should be up and running.

[Rosegarden-user] Busted Examples

2012-05-16 Thread steve conrad
I'd like to point out that my examples are broken again.

Track 9 should in all cases be a second drum track. But it comes up as
a non-percussion track in the wrong key instead.

I do this to make the notation more manageable since cymbals and
hi-hat are all notated as sharp notes whereas kick, snare and toms are
all naturals. This arrangement used to work in earlier versions of RG
but now it doesn't. Not actually sure if this is an issue with RG or
Fluidsynth.

In any case, changing track 9 so that it uses instrument 10 fixes the problem.

Sorry if I seem to be so persistently anal about a few example tunes,
but since the tunes are in C major, E minor and G minor having some
repetitive notes banging away in B major really does create a godawful
cacophony.

Re: [Rosegarden-user] Trouble with softsynths

2011-12-25 Thread steve conrad
The two most common reasons for this sort of thing are that either you
have no soundfont loaded in your softsynth, or else that you haven't
set up RG to route its midi output through the softsynth that you
have.

The solution to the first one will vary with the synth you're using,
but should be pretty easy to figure out. Qsynth has a pretty self
explanatory setup window for loading fonts.

To solve the second, from the main RG window go to Studio -> Manage
Midi Devices and make sure that your synth is showing as one of the
available midi outputs and that it is selected.

The whole getting the sound going thing is a bit of a barrier to
entry, but it gets easier from there.

Hope this helps.

Re: [Rosegarden-user] controlling attack?

2011-12-15 Thread steve conrad
A slightly more off topic solution is to make your own sound font
using swami or viena, and to create multiple velocity layers with
differing attack times. (Viena - not vienna - is a windows program,
but it works for me under wine).

I've made a few guitar fonts like this with progressively longer
attack times at lower velocity levels to create a volume swell effect.

Just be warned that both swami and viena are very odd and therefore
frustrating programs. For instance, both authors have seen fit to
reimplement their own file choosers which are significantly inferior
to the standard options available. Think they'd have enough to do just
dealing with the sf2 end of things, but go figure.

Re: [Rosegarden-user] Alternative repeats

2011-05-17 Thread steve conrad
Btw, as far as playing a second ending goes (rather than notating one)
RG will truncate a repeated segment as soon as it encounters any other
segment in that track, so it's pretty easy to get it to play an
alternate ending by simply plopping down the desired second ending as
a new segment in the appropriate place and then toggling the repeat
property of the segment you want to repeat. I do this quite a bit.

Re: [Rosegarden-user] Percussion is silent or sounds like piano

2011-04-12 Thread steve conrad
Again, I don't use timidity either (Why are you?)

However, I'd guess that the synth is set to use a percussion preset
not contained in your soundfont, hence the silence.

Try changing the percussion preset you are using until you get some sound.

Might want to try using fluidsynth instead also, since that's what
most folks on this list use.

Re: [Rosegarden-user] Sure Is Hard to Record Rosegarden's Output

2011-03-20 Thread steve conrad
Sorry if my ardour remarks gave the impression that I thought I needed
ardour to get a recording. I know it's an audio routing issue. Problem
is,  bouncing the master signal to a rosegarden input causes
rosegarden to lock up (on my system, anyway). And audacity seems a bit
daft at finding the signal. Presumably this has something to do with
using it as the default recorder in RG. For instance, audacity's
effects menu just lists RG's plugins while RG is running and things
like fade out or fade in are out taking a smoke. Think using anything
but audacity and screwing around with jack's path bay will solve the
problem.

Thanks for the help.

[Rosegarden-user] Sure Is Hard to Record Rosegarden's Output

2011-03-19 Thread steve conrad
Until lately, I haven't much used Rosegarden with both audio and midi data.

I was pleasantly surprised how easy it was to work with the audio in
RG. Especially how I could chop things up and move them around without
ending up with any nasty clicks.

However, I just couldn't get the thing recorded for use in the outside
world once I was done. Tried everything. Used Audacity with both jack
and alsa hosts. Even pulse running through jack. But nothing worked.
With jack, I could record qsynth or rosegarden's audio output, but not
both. With alsa nothing worked. I tried all reasonable audio input
sources (ie, I skipped the modem etc). Recording the system just gave
me silence. Also tried setting the input to system on one of RG's
audio channels and recording that way, but that just made RG hang.
Also sort of tried Ardour, but it just made my head spin. That's a
real tough program to figure out. Looks like it'd be nice if a fella
had the time to set aside for it though.

In the end, I just stuck a jumper cable from my headphone jack to my
line in and dumped it onto an RG audio track. But surely there's a
more elegant solution available.

Btw, the audio in question can be heard at
http://soundcloud.com/steveconrad/steve-conrad-rundle-saturday if
anyone's interested in hearing a pleasant little chord change having
the living crap beat out of it by an onslaught of filthy guitar
playing.

[Rosegarden-user] pulse audio & qjackctl autostart

2011-03-02 Thread steve conrad
I'm not always needing a full audiophile experience when I'm using
Rosegarden and frequently wish I could hear sound on a web page or use
some other non-jack aware sound app without all the bother of shutting
down jack to free up the sound card every time.

I also wanted to start regular old non-jack pulse after closing jack.

I found this page very helpful in getting pulse to run through jack:

http://www.harald-hoyer.de/linux/pulseaudio-and-jackd

However, since I pretty well always want to start qjackctl when I log
in, I wanted to setup qjackctl to start automatically minimized to the
system tray and to start pulse as a jack client. After a bit of
screwing around, I've managed to make this happen on my system.

Thought what I've figured out might be some help to others with
similar requirements.

First, of course, I had to add qjackctl to my startup programs
(Startmenu->System->System->Startup Applications on my OpenSuse11.3
system)

 The attached jpeg shows the relevant settings in qjackctl.

Execute Script On Startup:   killall pulseaudio
Execute Script After Startup: sleep 15; pulseaudio -nF ~/jack.pa &
Execute Script After Shutdown: killall pulse audio; killall jackd;
sleep 5; start-pulseaudio-x11

Please note that this won't work properly without the two sleep
commands. In the first instance, pulse will try to start before jack
is ready for it, in the second pulse will start in time to be killed
by the killall command. Also that without the ampersand at the end of
the second command qjackctl will hang waiting for the script to return
control.

If I set qjackctl to start jackd automatically, sometimes it fails to
start and I have to restart it manually, but I find this to be a
problem with qjackctl in general, so I just have it set up to be
started manually.

The file ~/jack.pa is as follows. It only differs from Harald Hoyer's
in that I've changed module-volume-restore to module-stream-restore
because pulse was complaining about it being obsolete:

#!/usr/bin/pulseaudio -nF
#
load-module module-jack-sink
load-module module-jack-source

load-module module-native-protocol-unix

Just a quick addendum.

Substituting module-volume-restore for module-stream-restore in
jack.pa seems to solve the problem with the server sometimes failing
to start on the first try.

i.e. doing things like in Harald Hoyer's example works properly, and
listening to pulse' nagging doesn't.

A slightly less crude approach is just to import the default studio into the
file (Studio->Import Default Studio), then make whatever ever changes are
necessary to get sound working ok and saving the file.

I did this with Djer-Fire and it seems to be working ok. Apparently just
making the changes and saving fails to get rid of whatever quirk it is in
the old soundblaster based studio that makes the sound not work.

As a follow up to this I notice, as did Michael, that if you close the file

Checking the Studio->Manage Midi Devices window, everything is as I left it

Restarting fluidsynth starts to solve the problem, but not quite, because
after a fluid restart Studio->Manage Midi Devices is now back to [No Port].
Hmm.

Reselecting [129:0] Synth Input Port gets the sound going again.

Kind of a pain though.

Some strange Rosegarden/Fluidsynth interaction going on there.

On a related note, I'm unable to get any sound at all from anything unless I
run Fluidsynth as root which isn't really how I like to do things.
Jack and Rosegarden are ok as a regular user and Fluidsynth shows up in the
relevant windows of qjackctl and rosegarden as if it's actually doing
something. The green light on qsynth even flashes along in time with the
music, but no sound. Not sure what's going on there.

Re: [Rosegarden-user] Re mapped channels with no sound

2011-02-22 Thread steve conrad
Since the older examples you write of were installed, Rosegarden has made
some changes to the way channels are setup.

"Beginning with version 10.02, Rosegarden no longer provides controls for
changing the channel associated with each MIDI instrument Instead each
instrument uses the same channel as its instruemnt number."

The first thing to get some sound going, is to go to the Studio->Manage MIDI
devices menu and make sure you have output sent to fluidsynth. (Some of
these examples were written to run through a soundblaster 128 rather than
fluidsynth, so when they don't find the soundblaster they just give up and
send midi output to [No Port]).

Here's what I see when I open this window after opening Bogus Surf Jam:

MIDI Outputs:

[129:0] Synth Input Port
[14:0] Midi Through Port
[No Port]  X

I get no sound because I have [No Port] selected.
Clicking on [129:0] Synth Input Port and closing the window will be enough
to give me some sort of sound.


However, Rosegarden doesn't do a perfect job of assigning sf2 patches to the
channels in these cases.

The most noticable problem for me, is that channel 9 which is supposed to be
the drum kit comes up as choir vocals which won't be in the right key or
anything.(C major rather than G minor). To fix this, select track 9 in that
middle area listing all the different tracks and then edit the track
parameters at the bottom left corner.. First check the check boxes for bank
and program. From the drop down menu for banks select bank 1:0 to get the
bank with all the drum kits in it. Then from the Program drop down menu
select what ever drum set you want.

For me this put everything to rights. But you might want to play around with
the Program assignment for the other tracks as well. Except of course that
for melodic instrument you'll want to be using bank 0:0 rather than bank
1:0.

This change from Rosegarden 10.02 has been fairly unkind to the examples
I've contributed since I invariable write the drums on two different tracks
one of which always comes up as a random out of tune racket. I do this
because all the cymbals and hi-hat positions can be written out without
accidentals in the key of B Major, while kick snare and toms are all
available without accidentals in the key of C. Also I find it easier to work
out as two tracks.

The three examples in question are Bogus Surf Jam, D'jer Fire and Stormy
Riders.

Perhaps I should fix these up and resubmit them. It is a bit of a pain to
get them going.

Hope this helps.

Re: [Rosegarden-user] Fave studio distro

2011-02-21 Thread steve conrad
I was using Artist X for quite a while.

http://www.artistx.org/site3/

It's a live distribution that's distributed as a live DVD image. Based on
Ubuntu 10.04. Comes with a whole shit load of linux sound apps, including
Rosegarden, jack and fluisynth. Also the default kernel has the real time
patch applied to it. Pretty handy, unless you're like me and find Ubuntu an
annoying linux distribution. Anyway, if you install it to the harddrive or a
USB stick and let it grind away at the updates, you'll end up with a pretty
current set of everything.

Personally, I much prefer running OpenSuse. Seems to be aimed at adults a
bit more than Ubuntu is. Only problem is, the realtime kernel for OpenSuse
11.3 won't boot on my system anymore (i.e. since I updated it last time). My
attempts to compile my own real time kernel always end up with my b43
wireless card not working. All messages on this subject have been met with
deafening silence at the linux-rt, linux wireless and OpenSuse mailing
lists. Not really sure what the matter is, but I won't get into it here.

My current solution is to run the Ubuntu real time kernel on OpenSuse 11.3.

This yields the rather odd (for an OpenSuse machine) uname results below:

steve@lizard:~> uname -a
Linux lizard 2.6.31-11-rt #154-Ubuntu SMP PREEMPT RT Wed Jun 9 12:28:53 UTC
2010 i686 i686 i386 GNU/Linux

Works very well for me, even if it is a bit of a hillybilly's truck with
mismatched body parts. ( I have one of those trucks of my own, btw ).
