afraid i don't, so would like to see what you come up with.
i am still using an old kenton box via an old midi<-->osc
bridge for getting 7-bit controller data into scsynth.
in case all else fails some (away from desk so untested) example
code below, it ought to be close as is extracted from trivial
curses program that reads parameter names from a text file and
shows controller state in a terminal. darcses at:
http://slavepianos.org/rd/sw/midi.osc/
http://slavepianos.org/rd/sw/tctl/
(midi.osc just sends the midi packets as osc blobs,
so pattern matching on the incoming packets is
actually pretty elegant, if you can remember the
midi constants, which i never can, the list i use is at
http://slavepianos.org/rd/sw/rsc3-midi/src/constants.scm)
regards,
rohan
