 Gate Mode keeps the output switched ON as long as the corresponding condition is true and turns it
off when the condition is over. For example, we can set a gate to be ON for as long as the MIDI clock
is running.
 Trigger Mode only sets the output ON when the corresponding condition first becomes true. The
output then turns off after a specific period of time (up to 125 milliseconds). The time period can be
selected directly, or you can use the default trigger period set up in the global settings for the patch.
 Retrigger Mode is rather like Gate mode in that it keeps the output switched ON as long as the
corresponding condition is true and turns it off when the condition is over. However, each time the
condition is signaled, Mutant Brain makes sure that the output is turned off for a very short period
before going back on again. For example, this allows for keyboard playing styles where you want to
control the sustain of a note by holding down a key, but also have an attack envelope which triggers
each time a new key is pressed, even if you are playing “legato” (only releasing a key after the next is
pressed). Or it can be used in any patch where you want an envelope to retrigger without a new note.
Select (gate) in the Trig setting for gate mode and (retrig) for retrigger mode. For Trigger mode you can
select a specific time in milliseconds or just select (trigger) to use the default trigger period defined in the
global settings.
The trigger period in global settings applies only to trigger mode. In retrig mode the “low” time is very short
(~1ms) and just enough to give a rising edge to trigger your synth gear.
 MIDI transport
MIDI has the concept of a “play” mode (or “transport”). When the transport is running, this means that
pattern-based devices and sequencers play notes in time with the MIDI clock. The transport can also be
stopped. MIDI controls playback with three messages:
 START - This message is usually sent by a master controller device when a slave device should reset
its play position to the beginning of a sequence and should start playing in time with MIDI clock
ticks. When this message is received, Mutant Brain triggers any gate with a “Transport restart” or
“Transport running” condition.
