I am having difficulty sending a MIDI bulk dump from a Yamaha SU-10 to a N264. No matter what I do, it seems the N264 has a memory overflow error. Its seq. memory maxes out at 64K, but I'm only trying to test a bulk dump of a 2 sec. sample. The MIDI channel on both are the same. I have a feeling the SU-10 is sending N264 data (somehow its looping via the MIDI cable). Any thoughts? Do I need to abandon a receiving unit with ltd memory and instead go after a used MDF2 somewhere?
