This is an very interesting application, and it is released as GPL software.
The only drawback on GNU/Linux is that sound is not working very well,
at least in my experience:
http://linuxmusicians.com/viewtopic.php?f=4&t=860
I dunno if there is a way to get better sound out of java applications.
Maybe some devs can help this application with ALSA and/or Jack support?
Kind regards,

I've uploaded Improvisor here, so you don't have to subscribe to yahoo

Maybe someone has a better place for it?

Hi,
I've found a very interesting application, Improvisor
*Impro-Visor* (short for “Improvisation Advisor”) is a music notation
program designed to help jazz musicians compose and hear solos
similar to ones that might be improvised. The objective is to improve
understanding of solo construction and tune chord changes. There are
other, secondary, things it can do, such as improvise on its own. It
has also been used for transcription. Because rhythm-section (e.g.
piano, bass, drums) accompaniment is automatically generated from
chords, Impro-Visor can be used as a play-along device. Now having a
wider array of accompaniment styles
<http://www.cs.hmc.edu/%7Ekeller/jazz/improvisor/Styles.htm>, its use
is not limited to jazz. Distributed with Impro-Visor is "The
Imaginary Book
<http://www.cs.hmc.edu/%7Ekeller/jazz/improvisor/ImaginaryBookIndex.html>",
a chords-only fakebook with chord progressions to about 2500 tunes.
http://www.cs.hmc.edu/~keller/jazz/improvisor/
Afaik it's GPL software and that makes me dreaming about having
Lilypond functionality in it... It has an midi export function, so
maybe the midi can be converted to lilypond?
Are people here working with this application?
Regards,
\r
Yes, this is the home of Impro-Visor.
It is GPL.
There is no Lilypond export to speak of, although it should be
possible. However, I don't believe I can work on it myself, as there
is too much else to do at the moment.
In the next release, we will be redirecting questions to the Yahoo!
impro-visor forum and improvisor(a)cs.hmc.edu will be phased out
(because it attracts too much spam).
I'd be happy to answer any other questions.

Ok, sorry I was to quick with that. The dev want to keep it together and
wants to give developers svn access if they want...
So I removed the link and source.

The JavaSound developers seem to have mistaken JACK for something like esd.
From http://www.jsresources.org/faq_misc.html#no_daemons :
**
"Why is there no artsd/esd support in Java Sound?
In Florian's and my opinion, mixing daemons like artsd, esd, JACK,
rplay, NAS, yiff, ... are hacks that work around a shortcoming of the
device drivers. We feel that mixing should be done either by the
soundcard hardware or in software by the device driver. For Windows
(DirectSound) and Solaris, this is self-evident, while Linux is lagging
behind. The OSS driver model is obsolete technology anyway, and ALSA can
do mixing in software with the dmix plug-in
<http://alsa.opensrc.org/index.php?page=DmixPlugin>. With this state of
affairs, all these discussions about mixing daemons could be settled
once for all. Never again would a sound program have to reinvent the
wheel with output plugins for /dev/dsp, ALSA, esd, arts, [you name it].
This would be a very efficient solution in terms of using (vs. wasting)
programmer time. It would even enable the coexistence of several mixing
daemons for backward compatibility. So why not do the obvious, elegant,
technically clean, (human) resource saving?"
Best,

Dave - I've had this argument with at least one of them online
(somewhere). No, this particular person didn't get it and I suspect
the others won't either. The critical arguments are:
(a) the linux kernel has a general design principle of providing
mechanism not policy
(b) audio mixing is generally best done in floating point format
(because otherwise its dog slow to simulate
fixed point on an x86-style processor) and the kernel cannot
do floating point math
(c) as you allude, JACK is not about providing just shared access
to the audio interface, but routing
between applications as well, which a kernel-based solution
has no role in. this is why JACK
is still so useful on OS X, even though CoreAudio *does*
support mixing multiple app

I wasn't quite finished ... multiple apps.
Please feel free to point these issues out to anyone you come into contact with.
