The yellow note in RG tells that two notes are in the place.
You can move one of these notes away with the mouse then delete it.

That's the Lilypond translation of RG's yellow note.

[Rosegarden-user] Lilypond output in relative mode

2016-01-14 Thread Leszek Wroński
Guys,

a quick follow-up to what I just wrote: is there a way to tell Rosegarden
to write pitches in relative mode when exporting to Lilypond? It seems to
be doing it in the absolute mode (
http://lilypond.org/doc/v2.18/Documentation/notation/writing-pitches ).

I am getting somewhere. Writing that longish post helped. After convert-ly
and tedious fixing of the little spacing mistakes which confuse Lilypond
and make it output a weird file I do see I may potentially have a score
worth working with ;)

Cheers,

Leszek.

Please ignore me. Frescobaldi can convert Absolute -> Relative with no problems.

Sorry for the spam!

[Rosegarden-user] From Rosegarden to Lilypond: some issues

2016-01-14 Thread Leszek Wroński
Guys,

my current goal is to set a small cantata I have in a (copy of a)
manuscript in Lilypond. I've been doing stuff like this for years inserting
notes by hand and thought I'd finally use a proper tool. So the idea is:

1. to record all the staves using Rosegarden;
2. make Rosegarden export a very basic score in a way recognized by
Frescobaldi, that is, Lilypond itself or MusicXML (I used the latter
standard many times using Finale);
3. make the score actually usable for performance using Frescobaldi.

I recorded two staves -- Violin 1 and BC. (Never mind the mistakes I made.)
Now, in the Notation view everything looks alright:

https://dl.dropboxusercontent.com/u/1554329/Pictures/01EverythingAlright%28butyellow%29.png

apart from the fact that the first note in the BC is yellow(?). I decided
to forget about that.

Now, this is the best thing I could obtain using 'Lilypond preview':

https://dl.dropboxusercontent.com/u/1554329/Pictures/02LYPREVIEWDoublenoteintheBC.png

Please notice a curious double note right at the start of the BC staff. And
weird slurs. I thought 'this actually looks OK; I'll get this thing sorted
out using Frescobaldi in no time!'

But nope. Here's what I get after exporting a Lilypond file in the newest
version Rosegarden 13.06 supports (2.12) and loading it in Frescobaldi:

https://dl.dropboxusercontent.com/u/1554329/Pictures/03LYdoublebassnoteANDweirdpitchstyle.png

Not only is the double note in the BC there, but also please notice the
weird (for me at least) style of writing pitches in the score editing
window to the left. I've never seen anything like that
and it's unworkable for me.

And here's what I got importing a MusicXML file generated by Rosegarden in
Frescobaldi:

https://dl.dropboxusercontent.com/u/1554329/Pictures/04MUSICXMLdoublenotesandlotsofwtfstuff.png

Notice more double notes, this time in the Violin staff, too. (I got the
same results when running musicxml2ly and loading the .ly file.)

Exporting MIDI and running midi2ly lead to even weirder results.

So the piece looks alright only in Rosegarden's notation window. Among the
others, the one that looks the best is the Lilypond preview of Rosegarden
itself.

Are there any magic tricks I could use to get Rosegarden to export a
Lilypond file which would correspond more with Rosegarden's notation view?
Or just any tricks I should know about when attempting to use Rosegarden as
a first link in a Lilypond production chain? (I already read
http://www.rosegardenmusic.com/wiki/creating_a_rosegarden_score_for_lilypond_export
. Normalizing rests did not help.)


In the meantime I will try to get the absolute newest versions of both
Rosegarden and Frescobaldi.


I'd be very grateful for any pointers.

Best regards,

Leszek.

So let's see, going through the old tutorial...

Rosegarden no longer creates new devices spontaneously.  All that
"external device 4" garbage is a thing of the past.  If you plug in or
run a new toy, you need to create a new device for the toy manually.

I recommend doing this from an empty document, then saving the result as
your new default studio.

> You can see I also connect my keyboard so it speaks to Rosegarden only.

Be aware that Rosegarden may not play nice with MIDI connections made
and broken with QJackCtl.

Historically, Rosegarden has always had the inconsistency that you have
to use the external connection manager for audio connections, and you
have to use the internal connection manager for MIDI connections.

I have no idea if anybody ever fixed that.  I still do it the old way,
and the old way still works.

The tutorial would have expected Rosegarden to create a device for
ZynAddSubFX with some stupid name like "external device 987" which you
would have edited to change the name.

It looks like what you did was change the default "General MIDI Device"
instead.  You changed the name to "ZYN" and changed the connection, but
the device still contains program definitions for General MIDI.  That's
why you're seeing "#1 (Acoustic Grand Piano)" instead of "#1."

The tutorial assumed you wouldn't have bothered setting up anything more
than that for ZynAddSubFX.  At the time I wrote that, it didn't respond
to external program changes.  You changed sounds on the thing by editing
inside ZynAddSubFX itself.  One classic piece I did used one preset
patch on channel 1, another on channel 10, etc., and I still have that
configuration stored in a separate .xmz file.  To play the old
composition, I have to load the old .xmz file into ZynAddSubFX manually,
if it even still works.

Managing all of that over time does get to be a pain in the ass, yes.

So anyway, if you want to experience the same thing as the tutorial,
start by creating a new device from scratch, rather than recycling the
existing one.  (You could also delete all the banks manually, but it's
easier to start fresh.)

With ZynAddSubFX, there is (or was, and probably still isn't) anything
to import.  It doesn't understand program changes, full stop, so the
only way to control what track plays what is by assigning the channel,
which is the same thing as the instrument number, #1, #2, #3, and so
forth.  (Make sure channel remains set to [Fixed], for reasons I won't
take time to explain at this time.)

I can't make up my mind which of two possible things is going wrong for you.

The easy one is to make sure Rosegarden is using #5 for the thing you
have told ZynAddSubFX to play on channel 5, etc.

I will reserve writing about the harder one for another time.

You've already gotten advice on using DSSI synth plugins.  Personally, I
prefer using QSynth externally.  I have it set up with three engines,
each with a different, dedicated soundfont, and that thing has been
running for months.  I forgot it was there.  It's all down to personal
preference in any case.

Re: [Rosegarden-user] Holger's suggestion

2016-01-10 Thread Leszek Wroński
Thank you very much again. Indeed Rosegarden displays a warning and tells
me to run 'sudo modprobe snd-rtctimer'. Unfortunately, I don't have that
module. I ran 'sudo modprobe snd-hrtimer' instead, but the warning still
appears. The 'details' section informs me "WARNING: using system timer with
only 250Hz resolution!"

I have an Intel Core i3-3220 CPU @ 3.30GHz × 4 PC with 8 GBs of RAM. I
didn't think I'd have CPU problems, but well, maybe that expectation was
wrong.

Still, now that I have the instruments set up, everytime I load up my file
the sound works properly and MIDI recording does too.

I will use you recommendation regarding JACK from now on.

Cheers,

Leszek.

Re: [Rosegarden-user] Holger's suggestion

2016-01-10 Thread Leszek Wroński
Thank you very much. Using the 'manage synth plugins' window I load the
FluidSynth DSSI plugin. Then using the editor I locate the soundfont and
choose the instrument. Then I can play and record with it with no problems.

However issues start when I want to use a different instrument in a
different track. I hope the intended functionality is that I can click. say
on Track 1, and my keyboard will play the instrument associated with Track
1, and when I click on Track 2, pressing the keys will play the instrument
associated with Track 2. So I want to have two different instruments from
the same soundfont associated with different tracks. The only way I was
able to do it was to load in the 'Manage Synth Plugins' menu the
Fluid-Synth DSSI plugin TWICE, for rows "1" and "2", and then load the
soundfont TWICE. I guess that's not the way to do this, since it's so
inefficient -- so how does one do this properly?

But the bigger problem is, once I have one copy of the plugin doing its
magic for Track 1, and another working its tricks for Track 2, so that the
instruments I hear really change when I click the different tracks, then
all the sounds are crackled. When I save the *.rg file, exit the program,
relaunch and load it again, the sound is fine. How can I avoid doing this
all the time?

Now, I'm trying to avoid using Jack to make connections at all. Not using
any standalone synth, it seems that to hear anything, I need to connect, in
the 'MIDI Playback' menu 'Rosegarden playback device' to MIDI Through. Is
that right?

Thank you very much again,

Leszek.

[Rosegarden-user] problem with basic functionality (tracks, instruments, ZynAddSubFX connection)

2016-01-09 Thread Leszek Wroński
Hello,

first, thanks and congratulations to everyone involved for making available
for free a piece of software which people around the world are using with
success! That said, my own attempts have only met with dismal failure and
so I'm coming here for help. I have a few newbie questions after I tried
for a few hours to do some really basic stuff; I have already read the
manual, the FAQ, and looked at the tutorials. Since I'm new to this and I'm
not sure what I'm doing wrong, I'm also not sure what the exact form of the
questions should be. Therefore this post needs to be rather long -- sorry
in advance. Please tell me if I'm making any basic mistakes. If you don't
have time and want to see the questions, scroll down to '*QUESTION x*'.

I'm using Ubuntu 14.04 LTS and the default Rosegarden installation: 13.06.
I have an Impact LX25 USB-MIDI keyboard.

My first modest goal is to successfully go through this tutorial:
http://www.rosegardenmusic.com/tutorials/supplemental/zyn/zyn.html

My 'fire up' sequence is 1) QjackCtl 2) ZynAddSubFX 3) Rosegarden.
I set up the Jack so that ZynAddSubFX will be producing sound to the
system:
https://dl.dropboxusercontent.com/u/1554329/Pictures/Connections_audio.png
I also set it up so that Rosegarden outputs MIDI to Zyn:
https://dl.dropboxusercontent.com/u/1554329/Pictures/Connections_ALSA.png

You can see I also connect my keyboard so it speaks to Rosegarden only.

I press Rosegarden's 'Manage MIDI devices' button and make sure what I see
resembles the connection I made by Jack, that is, I choose the ZynAddSubFX
port in the menu to the right. (Was the first connection made using Jack
superfluous? Does this hurt?) Now, I follow the tutorial and rename the
device to 'ZYN' (you can also see this in the png linked to above).

But now I'm at a total loss. I would assume that I would be able to change
instruments used in the track from inside Rosegarden. Still, the tutorial
does not suggest this; it tells me to choose '#1' on the Instrument List in
Track Parameters. But I see nothing like this there. As you can see here:
https://dl.dropboxusercontent.com/u/1554329/Pictures/Wrong_instrument_name.png
I see '#1 (Acoustic Grand Piano)', so it's obvious something's wrong.
Anyway, the whole list of instruments I can choose consists of '#x
(Acoustic Grand Piano)', for x in 1 to 16, except for '#10[D]'.

*QUESTION 1*
At this point my question is: why am I not seeing the banks and instruments
from Zyn inside Rosegarden? At some time I thought I should use the Studio
-> Manage Midi Devices -> Banks -> Import option, but there's no file named
in a way which would suggest a connection with Zyn.

Still, I want to continue the tutorial. So I set the instrument in
ZynAddSubFX to 'analogue bass' and yes, the sound changes when I press the
keys. At this moment I press the red dot, and start recording. At this
moment a segment called "Acoustic grand piano (recorded)" appears. I'm
still hearing the analogue bass sound. But when I play the segment back, I
hear that the first instrument in the first bank of Zyn, that is,
'Arpeggio1', is used. From that moment it is chosen in Zyn, and when I
press the keys on my keyboard I hear it instead of the bass I chose.

*QUESTION 2*
Why does recording a segment something in Rosegarden change the settings I
made in Zyn?

More worryingly, from that point on, I can choose what I want in Zyn, but
I'm still playing the 'Arpeggio1' instrument. I'm getting sick of it ;)

Any pointers on what I'm doing wrong? I've been a musician for many many
years, having spent also thousands of hours editing scores, and I'm only
now entering the realm of MIDI. I'd really appreciate any help whatsoever!

*BONUS QUESTION*
Now, this will probably be idiotic, but I need to ask this. Can I somehow
just play General MIDI instruments? Is this done by Timidity? I fired it up
but it doesn't show in the 'Audio' menu of Jack, so I can't tell it to
output any sound to the system.

Leszek Wronski.
