this is going to be a question for a ketron tech...and i will copy it to another forum as well as ketron italy...what is the EXACT (and all) information sent via ketron sd1 midi out when it starts a midi file? there is no reference to this in any of ketron's literature, and something it is doing automatically is changing sounds set up in the midifile i am trying to play..just the list of controller/sysex info would be enough as i can figure it out from there.
