Right on, looking forward to checking it out. Now I just need to
implement a nice interface to MIDI controllers. I was thinking of
creating some widgets like one where you can set different effects for
the 2 mouse axis, clicking on it would enable control of it. I've also
wanted to set up plugins for other types of controls like joysticks. I'm
still not sure how far I should go in the sequencer direction with
Swami, though.

Good to hear :) I also like the way the modulator editor turned out,
thanks to the pixmap-combo widget I ripped from libgal. I have been
experiencing a bug in the regular text combo widget, the bottom amount
source control combo will fail to pop up a selection list with scroll
bars when it is too close to the bottom of the screen. I've ran into
bugs with the option menu too, I hope these have been fixed in GTK 2.0.

Cool, I'll give it a try.

I've been thinking about porting Swami to Windows. Now that I don't have
to think about writing a special wavetable driver, there is really
nothing stopping me. I think I need to re-write libInstPatch first using
glib though, its rather un-portable as is. Does anyone know how I could
do a win32 cross compile? Also, is mingw32 a good choice? It would be
really neat to be able to release win32 versions without actually having
to have that evil operating system installed :) Cheers!
