Hey Dave,

Although RTMix has not been updated for a while, you can do this in 3 lines
of script and do so not only for MIDI->MIDI, but also for any combinations
of MIDI, OSC, generic network protocol and computer keyboard events. You can
also involve any type of MIDI/OSC/network-capable controller, keyboard keys,
and/or 6 different types of random number generation to alter parameters of
a particular data conversion.

Actually, come to think of it, you might be able to do some of what you are
trying to do in 1 line...*

*Obligatory handicap: the only real nuisance with RTMix is that it's still
using the old /dev/midi junk, but you can alleviate that easily with the
virmidi module.

If interested, see tutorials for more info, and if that fails, please do not
hesitate to bug me ;-)
