Just on a more serious note, amidst all this mayhem and frivolity, we
forked a project recently to more specifically add and modify a set of
tools for a defined purpose.
Unlike this trainwreck, we not only tried our best to do so in a
decent way, but the original author was thoroughly civilised about it,
and showed a lot of class in his positive and encouraging responses.
I certainly learned a lot from the process, and have even more respect
for Chris (Cannam) as a result.
It goes without saying that if Chris can use anything we write, then
he's most welcome to do so, and has our encouragement as well.
There's a way to do this that doesn't involve throwing digital
hatchets or burning anyone at the stake.

Subject: Python and MIDI orientation for a project
To: linux-audio-user <Linux-audio-user(a)lists.linuxaudio.org>
Hi folks.
I'm cooperating with a friend and fellow to improve his project
related to wiimote.
The project is Wiican[1]. In short, it is a tool (a system tray icon
actually) that makes it easier to connect the wiimote and configure
and create key mappings for use at your will. It's written in python
and uses bluez, hal with dbus, wminput and cwiid.
My goal is to add some layer in such a way that you can map wiimote
events to MIDI. And maybe, to include it on the next improved release
of Musix.
So, in adittion to my researches on the subject and what I already
know about MIDI CCs and so, I would like some advice and guidance
about how to:
- implement MIDI in python (which CCs are a must for you, create and
send MIDI messages, libs, bindings, reference projects),
- implement Jack and Alsa MIDI ports in python (libs, bindings,
reference projects),
... and every other interesting information or experiences on this.
Thanks in advance.

Easy to understand examples, thank you. Yes, this is what I mean by my
post, using GPL code means that nobody can take on the copyright without
violating the GPL.
Hi,
I'm currently playing with some code that sends SysEx data to ALSA using
RtMidi¹. I get an error reported by the latter one as soon as the size of the
message exceeds 16355 bytes. Unfortunately, I have such SysEx files of two
devices (namely a Waldorf Microwave I and a Digitech Studio Quad).
Can anyone comment whether this is a limitation in ALSA, and in case it is if
there are coding workarounds? AFAIR ALSA splits incoming SysEx-events into
chunks of 256 bytes if necessary. But I obviously overlooked that sending is
much harder when I played with SysEx data the last time :) .
Best regards,
ce

Woops... A little embarrassing. Thanks for letting me know.

Hi,
First release of the VCF LADSPA plugins ported to LV2:
(again, temporary download location)
http://www.jwm-art.net/default_downloads/vcf-lv2-0.0.1.tar.gz
notes:
some of the filters appear to work incorrectly in ardour2,
but appear to work correctly in lv2rack and ingen. i don't
yet know if this is a fault with my .ttl files, if anyone
with more knowledge than i can clarify it'd be much appreciated.
----------------
Second release of the NJL LADSPA plugins ported to LV2:
http://www.jwm-art.net/default_downloads/njl-lv2-0.0.2.tar.gz
changes:
* removed www. from LV2 URI prefixes of all plugins
* fixed port properties which specified 'integer' instead
of 'Integer'.
----------------
plugins have been (unthoroughly) tested in lv2rack, lv2_jack_host,
ingen, and ardour2. of the vcf plugins, the CV variants are mostly
untested.
Cheers,
James.

I *think* I responded to an email later in this thread, but in case it was
missed feel free to contact me off-list about whatever it is you were
wanting to ask and I'll attempt to help you out.

guitarix is a simple Linux Rock Guitar amplifier and is designed
to achieve nice thrash/metal/rock/blues guitar sounds.
Guitarix uses the Jack Audio Connection Kit as its audio backend
and brings in one input and two output ports to the jack graph.
Release 0.05.0-1 comes with some major changes:
* Completely new source structure by James
* add keyboard shortcuts
* improved skin handling
* add logging window
* improved preset handling
* add middle tone control
* reworked audio engine
* add bypass mode
* add engine state widget
Please read the README for more details regarding the new options.
have fun
________________________________________________________________________
The standalone version of guitarix is based on GTK2+.
But guitarix is also released as a suite of LADSPA plugins
and can be used in e.g. ardour.
guitarix is licensed under the GPL.
Project page with screenshots:
http://guitarix.sourceforge.net/
download:
http://sourceforge.net/projects/guitarix/
For capture, guitarix uses the external application
'jack_capture' (version >= 0.9.30) written by Kjetil
S. Matheussen. If you don't have it installed,
you can look here:

For extra Impulse Responses, guitarix uses the
convolution application 'jconv' created by Fons Adriaensen.

Hi there,
I'm using the lib lv2-plugin to write a plugin with c++ as you will know.
Now what's the proper way to get the sample rate?
Thanks in advance
