We have liftoff !

Well, good news, basic 303 jam mode working! Drum machine starts and syncs MSSIAH Bassline, and Spin Doctor custom patch lets me change patterns on the fly in time and change the cutoff frequency. Need to extend the midi map to cover the other controls like res, pitch etc but this is a good start, and tests/involves all the main bits of kit. Didn't use a mixer as the RY8 has a line in :)
