Hello all,
I've been asked by an animatronics technician for suggestions as how
they might go about solving a particular problem with a robot parrot
at a local theme park.
The robot's voice feature was designed around a PC/Windows platform
using Cool Edit Pro and scripted in Visual Basic. The idea is that
you say something to the parrot, it pitch shifts your voice then
repeats what you said two seconds later. If no-one talks to the
parrot for a while, it says "hello, my name is Sancho, talk to me".
Needless to say, they are having severe reliability problems with
Windows as it is being used day in, day out.
Can anyone suggest a suitable Linux solution for this parrot? I was
thinking about ecasound combined with a pitch shift plugin, if one
exists. If the solution could run entirely in RAM (CD booting,
perhaps?) then that would solve the problem of hard disk reliability.
Thanks
Daniel

Hi!
gmorgan is a .. Rhythm Station, an organ with auto-accompaniment and a "small"
Band in a Linux Box. Uses MIDI and the ALSA sequencer for play the rhythm
patterns. Styles, patterns , sounds, and the mixer settings, can be edited
and saved.
Program is released GNU/GPL version 2.
news v0.13 (18/08/2003)
----------------------------
- Added Record. Play, Load, Save and Export as Midi File of what you play.
- Minor bugs solved. Thanks to Robert Jonsson
- Added Stacatto-Legatto parameter for each accompaniment section.
- Re-arranged old patterns to the "correct" lengths.
- Solved bug in engine, now play the correct note length. That can modify
some patterns.

Ok, I admit it; I cannot figure out how to setup ALSA :-)
I *did* read alot of examples (on the ALSA wiki, in the evolution USB
MIDI Howto and the asoundrc.txt included with ALSA 0.9.6). Although I
think I understand the examples, I can't produce a working .asoundrc
myself. So much for the appologies, hope someone would be kind enough to
help me create a config file that would enable me to get midi into the
system. I'd also appreciate some pointers to relevant reading where the
concepts in ALSA are explained.
So far I compiled all relevant ALSA modules in the kernel (2.6.0-test3),
including emulation of OSS mixer, pcm and seq. Now sound is working
almost fine (PD doesn't love using the ALSA output, but csound, play,
xmms and alsaplayer works flawlessly). But I cannot make *any* program
recieve midi from the Evolution USB keyboard. I can't even get a reading
in either pd or aseqview. I run debian/unstable so there's no such thing
as /etc/modules.conf. It's was /etc/modutils/alsa, but now I moved it
out of the way. Instead I figured I'd start with ~/.asoundrc, since I
believe they should be the same. So for now, no config file is present.
Here's what aconnect -io says with the keyboard plugged in:
client 0: 'System' [type=kernel]
0 'Timer '
1 'Announce '
client 72: 'Rawmidi 1 - MK-249C USB MIDI keyboard' [type=kernel]
0 'MK-249C USB MIDI keyboard Port '
Thought that connecting the > of 'Rawmidi 1 - MK-249C USB MIDI keyboard'
to < of 'MIDI Viewer - Viewer port 0' in aconnectgui would result in
readings in aseqview, but no :-( Also tried to connect the < og the
keyboard to > of the viewer, same result.
Here's what shows up in /var/log/messages when I plug in the Evolution:

Looking for point to point telephony ideas ...
- each end has a half-duplex sound card, Linux/OSS and mic/speaker,
- maximum bandwidth is 28800 bps, outback Australia analog lines,
- Debian is preferred distribution, but we can cope with builds,
While I could spend a few weeks researching all the packages that
mention "phone" or "H.323" or "SIP", I'd rather ask some experts who
have tried it already, so as to use my time wisely.
I have looked already at speakfreely, linphone, and speex. speakfreely
appears to be reasonably complete, but not easy to use. linphone had a
host of dependencies that I was unable to resolve. speex as an encoder
and decoder works really well on voice recordings, but I've no idea yet
if it will help.
I have found the OpenH323 project, but the clients listed on their page
are all Windows.
Reply direct to me; I realise that the list is primarily focussed on
higher quality sound than mere telephony. ;-)

Hello -
I'm writing an article on Linux as an OS for audio production. I was
wondering if I could take a poll of what people think is the best and the
worst Linux audio software. I'm looking for sequencers, audio editors,
software synthesizers and samplers. Not really looking for CD burning
software or MP3 players.
Please reply directly to: soulsource(a)cox.net
Thanks...
