Moog MIDI MuRF MF-105M Usage Instructions page 23

Mute Mode cannot be used at the same time as Step Mode so if Note on
Value 108 is received, Mute Mode Note on values are ignored.
MIDI CCs 20-27 are treated with priority over the Note On Modes to
control the levels of Filters 1-8.
PATTERN CLOCK RESET: If the pattern clock is stopped due to a
MIDI Note mode or MIDI C20-27, MIDI Note 65 (F above Middle C)
will re-start the pattern animation. If the pattern clock is running, MIDI
Note 65 will re-set the pattern to step 1. If the sequencer is running on
Internal clock, the clock is re-synchronized to the instant you play MIDI
Note 65. If the sequencer is synced to MIDI clock, MIDI Note 65 will
reset the pattern to start again on the next clock step, while preserving
MIDI sync.
THE MIDI MURF AND SYSTEM EXCLUSIVE
The MIDI MuRF can respond to three types of System Exclusive
data: individual patterns, a complete set of 24 patterns, and firmware.
The details of the MIDI MuRF System Exclusive implementation is
published on the Moog website: www.moogmusic.com.
