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:

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,

Thats the user-manual or something. Where is the *.jar, *.zip or how
this is distributed?
The download link leads to Yahoo ...

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

Maybe someone has a better place for it?

Ok, sorry I was to quick with that.
"I'd prefer you didn't. If there are developers who are serious, I could
provide svn access to our repository. Right now there are 3 people who
are active. We are about to release version 4, which is almost a year
out from version 3.39 that is in the user group.
If you host it somewhere else, integration becomes more of a problem.
I realize that the code is not in the best of shape, partly due to the
fact that we have had lots of students working on it. I'd like to get it
in better condition, but time is an issue.

OK,
The application runs.
I can see my OSS midi-devices
Now what was the problem again? ... Ah yes, not so very nice sound,
right?
In application, select virmidi as output device. In QjackCtl, connect
virmid to nice jackified synthesizer of choice.
You might have to do (as root) first: modprobe snd-virmidi

re: Impro-Visor :
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 The OSS driver model is obsolete technology anyway, and ALSA can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
