Oops, I misread that, too. I remember writing a little
helper object for
Pd which triggers control messages for nonzero sample values in its
audio input. Once you have that, you can easily map that to a MIDI
message in Pd, so you might be able to use that for your purposes. The
object is called bit~ and is contained in this tarball:
http://prdownloads.sourceforge.net/q-lang/kcs-example.tar.gz
Of course, you then still need to write a Faust program which computes
the trigger pulses from its input, so that you can pipe the output
signal from that unit into bit~.
Cool! I will take a look at this just for reference. I guess I will have to
make my own way from there as graphical programming gives me the
heebie-jeebies.
