I'm getting really odd behavior when this patcher I'm working on is in a set. It's supposed to just send simple sysex commands to my Monomachine (plus I have another one for Machinedrum) and it works *sometimes*, but when it works seems almost random. It also seems capable of completely disabling MIDI for both devices, until I disconnect the physical cable. It also seems capable of blocking MIDI signals coming from the track it's on. Clearly I'm doing something wrong. Any help?
