Yes I know they're not the same. A mistake on my part. I meant a raw SySex dump. My appologies.

pmidi works fine for me.

AFAIK D50 is very similar to GR50. But GR50 has a 'one way' sysex dump option that is a data transfer without handshake (there is a possibility for handshake procedures as well). I have been using a one way dump into a MIDI sequencer. Playing it back into the unit (with any midi sequencer in Linux) results in checksum errors. The same procedure in MacOS (a long time ago) worked fine for me.
