The MIDI charts list the sampler (sound generator) section: notes 35-98 play the program's pads on its MIDI channel, Program Change 0-127 selects the program, channel pressure drives Note Repeat; the sequencer records and plays any channel message, which the performance routes cover. System Exclusive: recognized by the sequencer for recording only, no format given; not mapped. The manual gives no default pad-to-note table, so pads are not listed as triggers: notes 35-98 play whatever the program assigns to them. The MMC byte values are the MIDI standard's for the commands the addendum names; it does not print them. Untested on hardware.",
