Notes which are pushed out of the playable range by pitch bend will “plateau” at the limit.
Other CV sources
Mutant Brain’s four analog CV outputs can output signals other than musical note pitches. You can also use
them to output
Velocity of the most recently played note (Specify note input)
Continuous controller (CC#) value (Specify MIDI channel and CC number)
Pitch bend (Specify MIDI channel)
Channel aftertouch (Specify MIDI channel)
A CV which is linked to MIDI clock BPM (0-255 bpm range)
Fixed voltages for calibration etc.
For each of these you can specify the full CV voltage range from 1V up to 8V. Additional parameters needed
for a mapping are noted above. For example, to map a CC to a CV output we need to give the CC number and
the MIDI channel:
BPM to CV mode maps a BPM of 0-255 BPM over the full voltage range. The output is updated once per
beat, so updates are slow at low BPM and rapid changes in BPM will result in a “stepping” of the CV. If the
MIDI clock stops, this does not reset the CV (the button can be used).
A fixed voltage can be output by selecting the required voltage in the Range drop-down. The ability to output
a fixed voltage can be useful for calibrating modules.
Gate Outputs
General operation
Mutant Brain has twelve assignable gate outputs. Each of these outputs can be switched ON and OFF in
response to information coming in from MIDI.
When the gate output is ON, it outputs 5 Volt
When the gate output is OFF, it outputs 0 Volt
Depending how a gate output is mapped, it will switch ON and OFF when a corresponding even happens on
the MIDI input. There are three modes available:
