Hi all, this machine has midi issues I am certain. On reading other posts in several forums, it looks like it is not just me with the problem. After setting up the midi in section, as in, clock on, midi channel set as required, it simply goes it's own way as far as the clock input goes. Sometimes it appears to follow the ''leader'' so to speak, other times it just plays it's own timing. I am about ready to get rid of it and replace it with a Dr 770 or something. At times, it appears to depend on what drum kit is selected, and whatever pattern it was last set to. The manual is so light on information regarding the midi setup, but it should just be pretty basic, set clock on, midi channel to whatever, and that should be it, but it is a pain. Hope someone may have a clue before it goes out the door.
