None of the MIDI drag and drop export options work correctly. Regardless if you are exporting individual track lanes one at a time, or exporting All Tracks at once, every MIDI event gets exported to C3 in Logic Pro. As you know, the actual note triggers are routed chromatically to C1 to G1. Therefore, playback of the exported MIDI in the DAW just triggers C3 for every MIDI event, which corresponds to one of the Remix key switches, not the sample.
Also, pan automation (programmed into the PB4 sequence) is not being exported with the MIDI export either.
