INTERFACE
Connectors
Mutant Brain has the following connections:
A standard 5-pin MIDI input socket
Four 3.5mm jack sockets, labelled A through D, which output analog
control voltage signals
Twelve 3.5mm jack sockets, labelled 1 through 12, which output
digital gate signals
LEDs
Mutant Brain has 18 LED indicators:
The LED to the left of the MIDI port indicates MIDI activity
The LED to the right of the MIDI port usually indicates presence of a
MIDI clock and blinks on each beat. Some other actions use this LED
to show special statuses. These will be described later.
The 4 LEDs next to the CV outputs change brightness based to
indicate the voltage they are receiving.
The 12 LEDs next to the gate outputs flash when they receive a gate
or trigger.
Button
Mutant Brain is highly configurable, but all changes must be made over MIDI.
In fact, there is only one button on the module!
Press and release the button to reset all the outputs
. This will:
Clear all held MIDI notes
Turn off all gates (see note)
Set all CV outputs to zero (see note)
Reset note cycle modes to the first note
Reset clock dividers
The top right LED port blinks once when the reset is registered
A CV mapped to a pitch bend will go to it half-voltage position (no bend) on reset
A CV mapped to a fixed voltage will not reset
An “all notes off” gate will be triggered
The button also has a special use at power up so that new firmware can be uploaded.
This process will be
described later.
