Hi guys,

I totally agree with what Mr. Jones has said.  It works for me too.  Been
doing that since early days decades ago.

Stay safe all.

Re: [Rosegarden-user] JACK MIDI... Why?

2020-03-22 Thread ram
Hi Ted, et. al.

JACK MIDI is essential for "talking" to  wide range of software
synthesisers, e.g. the Bristol package (http://bristol.sourceforge.net/). 
There are work arounds to its absence, such as a2jmidid
(https://github.com/linuxaudio/a2jmidid/), but those are a pain to use and
are very sensitive to the startup order of various applications.

I hope that helps.

Rich Marschall

Re: [Rosegarden-user] LV2... Why?

2020-03-13 Thread ram
Yeah, I do something similar.  I record the raw audio tracks with Rosegarden
and then when I have all the tracks (and then some), I pull them into
Audacity for editing, mixing, and processing.  Outputs are usually stereo,
5.1, and 7.1 flac files to be merged with video.

I use a Linux cluster and quite a bit of external MIDI gear.  Jack, MIDI,
and Netjack interfacing are important to my uses.

Re: [Rosegarden-user] LV2... Why?

2020-03-13 Thread ram
Hi all,

Just my two cents.  We use Rosegarden regularly for the creation of video,
game, and museum display, soundtracks.

We don't use LV2 plugins, and very seldom use any plugins at all.

I, personally, would prefer if Rosegarden interfaced better with Jack/MIDI
and the like as most of the synthesis we do is on other machines, often
using NETJACK in one form or another.  Work arounds exist, but they are
cumbersome and annoying.

I'm sorry that I don't contribute as much technically, and otherwise, to
the project than I used to, but my company is still a heavy Rosegarden
user and we can contribute significant resources if need be.

Hi guys,

I agree, JACK-MIDI would be more immediately useful that some other

One thing I really like about both Cinelerra and Blender is they allow one
to use clusters of Linux boxen so one can really throw alot of "grunt" at
rendering.  Totally agree about the use of ffmpeg for various conversions,
especially if one's source material has various resolutions, formats, and
frame rates.

All Linux video editors (and ffmpeg) can benefit mightily from having GPU
subsystem with several thousand cores with the proprietary AMD/ATI or
NVidia drivers installed along with their corresponding OpenGL and OpenCL
libraries and routines.

My friends tell me Blender can do anything, except apparently be easy for
me to learn how to use ;-)  Blender rendering services on remote "cloud"
supercomputers is also readily available if you have the Internet speeds
to use them (we don't in Australia with its aged copper twisted pair
infrastructure).

Hope this helpful.

[Rosegarden-user] Video editing on Linux

2016-08-14 Thread ram
Hi Michael,

With respect to:

Try Cinelerra (https://cinelerra-cv.org/) it may be the middle ground you
are looking for.

Of course, video editing can be done in Blender (https://www.blender.org/)
which many of my friends use, but I've found Blender's learning curve
rather steep, almost cliff like.

OpenShot (http://www.openshot.org/) is relatively easy to use, but may not
be as full featured as you like.

As with music software there is an inherent trade-off between "easy to
use" and "full featured".

Since the vast majority of the movie industry uses Linux for video
manipulation, CGI, and editing, there are good reasons to stay with Linux
as your platform of choice.

Best regards,

Rich Marschall

Never mind, I've figured it out, it is the use of the Merge function under
the File menu.  A bit strange it doesn't bring things in in the same
notional key as the earlier parts of the composition, but that was easily
fixed afterwards.

I know I could brute force it by playing the new MIDI material on one

Hydrogen works real well as a MIDI synth to be played by RoseGarden, at
least when using Jack/NetJack.  I do this all the time.  For larger
percussion sections I find it easier to use RoseGarden for the sequencing
than Hydrogen's native interface.

Re: [Rosegarden-user] Humanizing MIDI tracks

2016-04-14 Thread ram
With respect to all the issues with respect to notation, compositional
aids, humanized tracks, etc:

I kinda hate to bring it up, but perhaps the RoseGarden developers should
take a look at another Open Source project --- Impro-Visor
and "lift a whole bunch of tools out of it.

As computers continue to get more powerful, I can envisage the two
projects merging.  Right now, nearly all professionals using Impro-Visor
and the vast majority of students generate files they touch up and
orchestrate in RoseGarden.

Such an application would not be "thin", I've got around 2000 cores
working on Impro-Visor routinely with another thousand or so readily
available, so that is serious music AI.  RoseGarden then applies serious
leverage to Impro-Visor results.

OK, I've said it.  A live grenade in the room.

Have fun,

You are right.  I remember these things from when I was a young man and
I'm an old man now.  On Linux you can set up a pitch to MIDI converter in
AMS (ALSA Modular Synthesizer) and  a MIDI output envelope tracker,
without too much trouble.  Or, you can output the pitch and envelope
information as a control voltage (CV) if you have a DC coupled soundcard 
(usually those are the really really cheap ones) and use that to control
an analog synthesizer with a guitar as the controller.

Once you start coupling innovative controllers with AMS and Rosegarden and
perhaps back the other way also, things get really interesting and
creative.
Have fun!

Further to the above, RoseGarden can use the Hydrogen drum synthesizer so
if you are looking for just randomization of rhythm that would be a way to
go.  On physical pitched instruments real humans don't actually make
"random" errors but instead tend to particular errors due to physical
difficulty of executing that part of the performance.  Hence the use of
"Amateur" soundfonts when one wants to simulate a high school band or
drunken performers.

The "interpret" function under the notation editor in the menu "adjust"

Thanks for the comment about the Mozart piece.  Are you old enough to get
the joke in the "album title" ?

Avoiding "dungleflungies" is why when I get a configuration working (in
this case a Debian Squeeze cluster with around 3k cores), I don't mess
with it.  Although I use the Debian Squeeze versions of Audacity quite a
lot for final mastering, I haven't seriously used Ardour in years.  For
me, the interface is non-intuitive and the set-up is painful.

With respect to music, math, language, and programming: I'm "good" at math
(you can Google that one ;-) and "decent" at music.  I used to be a
reasonable programmer but most of my skills there have been overtaken by
more modern object oriented programming languages.  I've never been good
at languages, at least relative to my friends who seem to all speak a half
a dozen, understand a dozen more, and read several dozen.  The human
language guys seem to be the same ones who are good at machine languages
as well.  No wonder they are fully international, they can run a
programming team anywhere from anywhere.

[Rosegarden-user] RoseGarden with Plug-Ins -- stability

2015-11-28 Thread ram
Hi guys,

The stability of RoseGarden with its plug-ins is pretty good.  The
following was recently done using only RoseGarden plug-ins (on Debian
Squeeze):

ftp://www.hydrophones.com/Mozart-K488--88p2kHz.flac

It is almost a half hour long and beat the living daylights out of the
plug-in functionality.

I always did a save before changing a plug-in.  I did get a few crashes
but not always on the same plug-in (e.g. the plug-in could be used on
another track and worked just fine).  As far as I could tell, in this
large practical example, no RoseGarden plug-in crashed consistently, and
running into a crash was a rare event.

Rich Marschall

P.S.  Yes, I know the rendition of Mozart's K488 is politically incorrect.
 It is suitable for "Future Noir" or "Tech Noir" videos.  It is under the
CC-BY-NC-SA 4.0 license and is bound to show up in some interesting places
;-)

Re: [Rosegarden-user] How should I use RoseGarden

2015-09-17 Thread ram
Hi Anton,

My friends and I use Rosegarden with JACK and pretty much forget about the
plugins.  We use a combination of external hardware synths and soft
synths.
Fluidsynth with soundfonts remains popular (the website http://wowsia.com
provides an almost endless supply, I think they have over a TeraByte
worth).

We also use an extension on JACK (that used to be called NetJACK, but has
been incorporated into recent versions of JACK) see for example:

https://github.com/jackaudio/jackaudio.github.com/wiki/WalkThrough_User_NetJack

and,

https://github.com/jackaudio/jackaudio.github.com/wiki/WalkThrough_User_NetJack2

This allows soft synths to run on separate dedicated machines, which may
or may not, have analog sound capability.

My main synth studio rig has one machine with a high-end multichannel
sound card that does nothing much more than take inputs from other
devices.  Synthesis is all done on other machines as is recording. 
RoseGarden is run on the recording machine with a big monitor and graphics
cards.  NetJack ties it all together.

Examples of the results can be heard on the Jazz channels of:

http://finevenuemusic.com

and

http://lowcostrestaurantmusic.com

The "Space of Hearts" channels includes work by other artists, but also
mostly done with RoseGarden on Linux.

Hope this helps,

Rich Marschall

 every few chapters (combine with Marquis de Sade?) I could sell eleventy

 In reality, I'm never going to write a novel, because I can't turn out a
 story that goes for more than about 15 pages.  Writing is harder than it
 looks, and it eats vast amounts of time.

Hey!  With a plot like that we could make an OPERA, and use RoseGarden to

Re: [Rosegarden-user] An oddity!

I may start the composition process with (other Linux) tools than
RoseGarden, but my final compositions are almost always put together in
RoseGarden with the final mix being done in Audacity.  The few exceptions
are those things that I do live.

I've also installed RoseGarden on Linux boxen my company has supplied to
media studies departments of universities and to private music schools. 
The response from the teachers and students has always been very
favorable.  I am certain most of those graduates continue to use
RoseGarden professionally.

Rosegarden is definitely a core Linux media creation application.  I fully
agree:  Long live RoseGarden!

 Use a Kernel with HZ1000 set. Those kernel packages have usually
 lowlatency in their name. The message vanishes then.

 Lowlatency kernels are good both for Rosegarden and for JACK.


Unfortunately they tend NOT TO WORK with proprietary graphics drivers from
AMD/ATI and NVidia.

My recommendation, is to ignore the message, and try Rosegarden out with
your existing configuration and see if you can notice any problems/delays.
If there is a problem you can always switch kernels IF the version you are
using is not necessary for the graphics driver you are using.

Hi,

I haven't found it to make any practical difference on (semi) modern
hardware.  If you are using external MIDI synths, keyboards, filters, and
other accessories, particularly legacy ones, they introduce their own
errors which are bigger.  Perhaps if you a sequencing an entire orchestra
it might, perhaps, just maybe ;-)

 That's strange, it should have everything Ubuntu has in terms of

You're right, that is strange.  My company has two Ubuntu Studio machines
connected to our Linux cluster.  The cluster itself consists of mostly
Debian boxen but there is a CentOS machine in there.  Some Knoppix
machines are also sometimes coupled in.  We use fixed IP addresses which
is a requirement of some of the back-end video rendering software we use. 
Initial setup is a bit tedious but the combined grunt of the cluster is
formidable.

 Software avoids instruments that need exact timings.

 Sure it's so general? Isn't this doable by setting JACK latency low? I
 thinking of Rosegarden doing only midi and hooking instruments (e.g.
 fluidsynth) through alsa-midi etc.


I agree, I've not found it to be a problem with Real Time versions of
Linux or recent versions of JACK/Alsa.

What IS often a problem is how certain SoundFonts are made up (if you are
using a SoundFont synth).  Many SoundFonts have uneven delays between
samples/instruments which is hard to compensate for.  The solution is to
just go edit the SoundFont with Swami and line everything up.

Likewise when using other sampled synths, such as Hydrogen.  The samples
can be uneven with respect to start times.

Other 'soft synths' usually have delays but they are usually pretty
consistent which is much less of a problem.  They are no worse, and
usually better, than external MIDI hardware synths.

Of course, all bets are off if the CPU(s) are overloaded.  More than a 50
percent system load is getting risky for audio work.  This should not be a
problem even on modest hardware if one keeps the number of simultaneous
tracks down to a reasonably sane number.
