Dear Csounders,
Well - it's not really a contest, but... I could really use some help
to come up with an elegant and efficient solution by tomorrow afternoon.
I am looking for an instrument in Csound that we can include on the
One Laptop Per Child computer
that will play any General MIDI file we throw at it. (In the way
that Quicktime Musical Instruments do on the Mac.)
The two solutions I have been experimenting with, and modifying
slightly, are those designed by:
1. David Akbari - from the examples in his pgmin UDO
2. Istvan Varga - from his advanced fluidsynth example in the manual.
Istvan's Fluidsynth solution is perfect - BUT - too slow. It uses up
over 80% of my PowerBook G4 CPU
and on the slower OLPC machines, it chugs to a halt.
David's sfplay and pgmin UDO solution is more efficient and would do
the trick, but there is a problem with the pgmin UDO and with the
fact that some presets seem to change the instrument that is being used.
So....
Have any of you designed a General MIDI Instrument in Csound that you
would dare to share?
Would you like to try out the Istvan and Akbari solutions and see if
you can improve them?
http://csounds.com/olpc/gmSoundFontPlayer.zipI have included a few midifiles (one composed by the king of
Thailand!) and a general midi soundfont bank too.
Any input, suggestions, solutions received and/or posted before
tomorrow at 3pm would be
most appreciated and (if they work out) included in the Beta1-demos
for the One Laptop Per Child Computer.
Thanks for your help and advice.
Dr. B.
(at 3:53am...... uuughhhhhh --- and I start work at 6am.....

all nighters just about every week!)
