I play a T2 , and sometimes use a midi accordion with a ketron sd2 . If I run a midi out/thru from the sd2 to the tyros, it generates incorrect chords (7th instead of major) using accordion left hand buttons. I have the midi transmit and receive channels set correctly (it works with sd2), but it won't work properly thru T2. I need to generate chord changes and rhythms from the left hand of the accordion in order to use keyboard as a sound module for accordion. Is there a patch to be loaded, or a control change or a sysex command I am missing?
