• Play/stop/continue - (Lights up green.) This also works under any
condition.
• "Auto-play" feature: When the Sequencer button is lit, the pattern will
start to play, and continue as long you hold a note on the keyboard.
Play from beginning lights up, and the pattern continues until you
release the note. Play the note again, and the pattern starts over from
the beginning.
NOTE: The pattern auto-plays its programmed pitches if you play middle C,
but it transposes if you play another note (and if you play subsequent notes,
it transposes again without stopping, provided you connect the notes closely
enough). For that reason, it's a good idea to program/record patterns with C as
the base note.
• Tempo, rate, and playback controls
NOTE: These apply to both Sequencer and Arpeggiator modes.
MIDI Sync ignores the internal tempo and locks the Sequencer and Arpeggiator
to incoming MIDI clock. Use this if you're using the MatrixBrute with a MIDI
sequencer or other MIDI equipment. External Sync may come from three
sources: MIDI In, MIDI over USB and Sync port. You can choose the source you
wish to use with the MIDI Control Center.
