My M-Audio Keystation49e or Keystation61es causes my Roland or other sound module to drop notes or get MIDI communication errors when plugged directly in, what can I do?

As of March 2005, this is a known issue with a few Keystations and some rack module synthesizers and samplers, we’ve found mostly older Roland modules have this problem. The problem, however, has been resolved with newly shipping controller keyboards. If you have a Keystation with these symptoms, you can contact M-Audio or Sweetwater tech support and send it in for a warranty board replacement with the board that will resolve this issue.
