Re: [pygame] 2P: Sound synthesis / drum machine

[Luke Paireepinart <rabidpoobear@xxxxxxxxx>]

In general Python's not so fast, and you probably don't want to be
generating synth effects in it.  But it works great to control synths
written in other languages.
I'd say you might want to look into using CSound or Supercollider as
your synth basis and controlling the synth parameters via your Python
interface.  That's likely to be the easiest / best way to get it
"right".  I would also do the MIDI input on the Python side if I were
you, it will likely be easier that way.

I've worked on a simple Kaossilator-type pygame program, taking the
x/y coordinates and sending them to a Supercollider synth.  Was quite
fast and worked well.

Good luck though, and keep me updated!  I'm always interested to see
how people use Python for sound synthesis, 'cause it's one of the
fields I'm very interested in.
