Hi all
My name is Thijs and i have been helping out with Hydrogen for some time now
(mainly manual, website and a tiny bit of coding)
Anyway, since jack_session support was recently added to Hydrogen (in V0.9.6
that is currently still in development but available from svn via
hydrogen-music.org) i decided to test jack_session a bit and i must say i'm
really exited about this :-)
IMHO this is the most critical piece of the puzzle and it makes linux audio
_so_ much more usable! so lots of KUDOS to everyone that has been working
on it !!
I have done several 'intro sessions' for Mac audio users and they are
generally really impressed with what they see, but the lack of a good
session management mechanism is a real showstopper for them... (i know
there are other options, but none of those have ever allowed me to truly
save my session *at any given moment*)
however, the first thing that slowed me down was simply knowing what apps
already support jack_session
i know that jack_session is fairly new, so it's normal that some info is
missing, but it would be great if the websites out there that list the
available linux audio apps (like
http://apps.linuxaudio.org/apps/categories/jack) would also indicate if the
app supports jack_session
the jack_session page on the jackaudio.org
wiki<http://trac.jackaudio.org/wiki/WalkThrough/User/jack_session>also
lists a number of apps, but i don't think it's up to date, is it ?
any comments?
grtz
Thijs
PS: i'd be happy to help out with documenting jack_session if needed
PS: it would be nice to have a 'jack_session enabled app' banner to put on
the site of the apps that support it. graphical designers ?

Brand new LV2 plugin soft synth here. The Newtonator (v0.5.0) features:
 * LV2-compliant synth plugin
 * Simple, easy-to-use GTK-based GUI
 * 3-note polyphony (err, um, until I can do some serious optimization)
 * "Unique" synthesis algorithm (Tuna Pagan Fellowship)
The Newtonator specializes in making crazy, harsh sounds, so if you're
looking for some sounds to produce the next Yanni album, keep
looking. Please refer to the user manual
(http://newtonator.sourceforge.net/manual/index.html) for more gory
details.
Download: http://sourceforge.net/projects/newtonator/files/newtonator-0.5.0.tar.gz/do…
NOTE: This plugin was written against the excellent libraries included in
the lv2-c++-tools package written by Lars Luthman. However, as of v1.0.4,
the GUI library only supports rev. 2 of the LV2 specification, so it may
have problems on newer hosts (though I have done some (very) preliminary
testing against Ardour3 and it seems to work ok). Alpha testing mostly
done against zynjacku and Elven (comes with ll-plugins package) hosts.
This puppy's in beta, so feel free to get in touch with me at the project
forum (https://sourceforge.net/projects/newtonator/forums/forum/1820765)
or submit a bug if needed.
Thanks, and have fun.

Hi,
during the process of writing a new small jack sampler which fits my
workflow I came up with this little scheme to solve the UI/engine
decoupling problem. For the purpose of spreading the idea or
alternatively getting answers about how it's broken and sucks I decided
to write a little article describing it..
http://178.63.2.231/~tapas/wordpress/?page_id=45
The (largely unfinished and unusable) sampler project is here:
https://github.com/fps/jass
Let me have it..

Hello everyone,
Every one knows Yoshimi, the fork of ZynAddSubFx.
One thing was lacking to yoshimi to be perfect: to be nearly fully
controlled by midi controls ( no OSC, sorry ).
ZynAddSubFx had possibilities to control a few parameters with
complicated NRPN, Yoshimi recently had ( in the test versions ) some
features too.
But now I'm proud to announce you the work of licnep ( not me, I'm just
a bug reporter ) who made the "midiLearn" function for yoshimi. It's not
stable for now because it's recent, and not full, but here are the
present features:
* Control System effects, Part Insert Effects
* Master/Part Volume, Pan, System Effect Sends
* Most of ADsynth parameters
* Add/Remove controller
* detect the channel and the number
* reset the knob ( its position )
I think it's a feature that's very useful and could help many
yoshimi/zyn users.
To use it, that's simple: connect your controller to yoshimi,
right-click on a blue knob ( yellow are ones which are not supported for
now ) and click "midi Learn" move your controller, it detects
automatically the controller.
To see and modify controllers, go to the Yoshimi> MIDI controllers menu.
To erase midi control of a knob, simply right click on it and click on
"remove midi control"
Here is the gitHub repository: https://github.com/licnep/yoshimi
To download and install it, follow the explications link ( gitHub ):
https://github.com/licnep/yoshimi/wiki/How-to
A light page to understand how to control others not implemented
controllers:
https://github.com/licnep/yoshimi/wiki/Source-code
Pages to follow the news of the project:
Facebook: https://www.facebook.com/pages/Yoshimi-midi-learn/224823617534934
Twitter: http://twitter.com/#!/YoshimiMIDI
So if you're interrested, all bug requests are deeply recommended.
Cheers,
Louis CHEREL.
Hi,
I decided, on a whim [release early, release often], that the code is
somewhat usable now. Grab the software via
git clone https://github.com/fps/jass.git
then read the INSTALL file..
https://github.com/fps/jass/blob/master/INSTALL
There might be quite a few kinks and development will stay active the
next few days.. Patches for features/fixes gladly accepted..
A screenshot from just an hour ago or so:
http://i.imgur.com/xygf6.png
Quick Tut:
Shift-Doubleclick to audit a sample
Doubleclick to load it..
Known Bugs:
- Velocity mapping still broken (at least the GUI part)
TODO:
- Add nice piano widget to set note ranges and central note..
- Actually use libsamplerate to convert sample to jack samplerate
Regards,
Flo

Many thanks. I'll try it and report back.
