I am new here, so this question may have been already answered previously. My search did not turn anything up. After 10 years of reliable use as both a keyboard to play out and a source of MIDI for other modules, I am not getting any MIDI out. Inside my studio I have a Kurzweil 1200PX, Roland vintage synth module, DX mole and other things that now are not receiving the midi from the M50. I dragged out the 35 year old monstrous 88 key Kawai controller I used to use before and MIDI is received on the other modules from the Kawai. Inside the M50 there is a rudimentary MIDI window setting that appears to be correct. Has anyone else had this problem?
