Hi all,
I just found this list after being directed to the IRC channel over the
weekend. I'm new here! Lately I've been dabbling in a bit of open-source
audio development (I say open-source rather than linux, because I've been
dabbling on both linux and windows).
Anyhow, amongst other things I've been trying to teach myself about DSP, so
I wrote a really (really, really, really) naive distortion plugin. I was
wondering if anyone would be interested in taking a look at it and giving
me some feedback, and tips on where to go next.
I wrote a little about it here:
http://guysherman.com/2015/08/30/my-first-ever-audio-plugin/
And the code is at: https://github.com/guysherman/si-plugins
I've got some other projects on the boil that I've been talking about with
the crew from the Ardour list, which I'll mention here when they take shape
a little more.
Cheers,
Guy.

Greetings,
I am fairly new to USB dev (in linux in particular, but also in general), but I
would very much like to try to get support for the above device working in
snd-usb-audio.
- Is this an appropriate place to discuss snd-usb-audio?
- Are there any recommended reading pointers for behavior of the quirk table?
I patched parse_audio_format_rates_v2(), get_sample_rate_v2(), and
set_sample_rate_v2(), and through some sort of beginner luck was able to get
aplay audio out of the first two channels. That was incomplete hackery though
(eg fixed sample rate), and I would like to learn how to properly add quirk
support. There have been other reports that this device worked OOTB, but I
fail to see how!
I've also been examining the traffic to the device with wireshark and a
win7 vm, but the learning curve for USB is a bit steep, so I am digesting. (:
If anyone can provide suggestions on lsusb output alone, here's what I have:

Greg

Qtractor 0.7.8 - The Snobby Graviton is out!
-------------------------------------------
So it's first solstice'16...
The world sure is a harsh mistress... yeah, you read that right! <a
href="http://en.wikipedia.org/wiki/The_Moon_Is_a_Harsh_Mistress">Heinlein's
Moon</a> have been just intentionally rephrased. Yeah, whatever.
Just about when the UK vs. EU is there under close scrutiny and sizzling
winds of trumpeting (pun intended, again) coming from the other side of
the pond, we all should mark the days we're living in.
No worries: we still have some feeble but comforting news:
Qtractor 0.7.8 (snobby graviton) is out!
Nevertheless ;)
Qtractor [1] is an audio/MIDI multi-track sequencer application
written in C++ with the Qt framework [2]. Target platform is Linux,
where the Jack Audio Connection Kit (JACK [3]) for audio and the
Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main
infrastructures to evolve as a fairly-featured Linux desktop audio
workstation GUI, specially dedicated to the personal home-studio.
Change-log:
- MIDI file track names (and any other SMF META events) are now
converted to and from the base ASCII/Latin-1 encoding, as much to
prevent invalid SMF whenever non-Latin-1 UTF-8 encoded MIDI track names
are given.
- MIDI file tempo-map and location markers import/export is now
hopefully corrected, after almost a decade in mistake, regarding MIDI
resolution conversion, when different than current session's setting
(TPQN, ticks-per-quarter-note aka. ticks-per-beat, etc.)
- Introducing LV2 UI Show interface support for other types than Qt,
Gtk, X11 and lv2_external_ui.
- Prevent any visual updates while exporting (freewheeling) audio tracks
that have at least one plugin activate state automation enabled for
playback (as much for not showing messages like "QObject::connect:
Cannot queue arguments of type 'QVector<int>'"... anymore).
- The common buses management dialog (View/Buses...) sees the
superfluous Refresh button finally removed, while two new button
commands take its place: (move) Up and Down.
- LV2 plug-in Patch support has been added and LV2 plug-ins parameter
properties manipulation is now accessible on the generic plug-in
properties dialog.
- Fixed a recently introduced bug, that rendered all but one plug-in
instance to silence, affecting only DSSI plug-ins which implement
DSSI_Descriptor::run_multiple_synths() eg. fluidsynth-dssi, hexter, etc.

Just tried to run a mididing [sic?] with Boost 1.60. Using the latest git
of mididings. Got this:
TypeError: No to_python (by-value) converter found for C++ type:
boost::shared_ptr<mididings::backend::BackendBase>
I found many similar reports with other tools, all referencing Boost 1.60,
all talking about reverts to Boost 1.5* as the solution. Anyone have other
ideas? I'd rather not revert Boost if I don't have to do so.

researchers and artists. IEM offers education to students in composition
and computer music, sound engineering, contemporary music performance
and musicology. It is well connected to the University of Technology,
the University of Graz as well as to the University of Applied Sciences
Joanneum through three joint study programs.
