I just purchased an MX88 and I also use Logic Pro X. I successfully installed the driver and everything needed to make the Audio/MIDI work via USB. My problem is that when I press record, it seems like Logic is sending back random MIDI data that sets off some notes on the MX88. I have Local Control Off and it doesn't matter if I have the DAW Remote on or off. If I have the ARP on then it triggers an arpeggio in the MX, and if it's off, it'll just hit a few random notes. It's just strange in that it only happens when I hit the record button. Any thoughts? Thanks.
