 CONTINUE - This message is usually sent by a master controller device when a slave sequencer pick
up playing from its current position. When this message is received, Mutant Brain triggers any gate
with a “Transport running” condition.
 STOP - This message stops playback at the current position. When this message is received, Mutant
Brain triggers any gate with a “Transport stop” condition. It should be noted that the MIDI clock tick
messages (which define the BPM) continue to be sent by the master device even when the transport
is stopped.
 MIDI clock divisions
A very useful feature of Mutant Brain is the ability to output clock pulses when MIDI clock tick messages are
received. A MIDI clock master defines the BPM by sending out 24 of these tick messages for every “beat”
(quarter note) so at 120bpm, 48 ticks are received every second. Mutant Brain can trigger its gate outputs in
response to these tick message.
Most usefully, you can specify the rate at which the gate output will fire, as a division of the tempo. Mutant
Brain can output a clock at the following rates:
 1/32nd note - 3 ticks
 1/16 note triplet - 4 ticks
 1/16 note - 6 ticks
 1/8 note triplet - 8 ticks
 1/16 dotted note - 9 ticks
 1/8 note - 12 ticks
 1/4 note triplet - 16 ticks
 1/8 dotted note - 18 ticks
 1/4 note (beat) - 24 ticks
 1/2 note triplet - 32 ticks
 1/4 dotted note - 36 ticks
 1/2 note - 48 ticks
 1/2 dotted note - 72 ticks
 whole note - 96 ticks
 24ppqn – one pulse every MIDI tick
 CC based gates and triggers
A gate output can be tied to a specific MIDI continuous controller (CC) value such that the gate is activated
when the CC value goes above or below the threshold. For example, we can set a gate to activate when
CC#10 is above the value 64:
We can also set a gate to trigger when a CC is below a threshold. In all cases the gate cannot trigger until we
receive the current value of the CC from MIDI (i.e. when we first connect Mutant Brain we don’t know the
current CC value until it changes).
