12 Step Key Behavior
12 Step uses Note Modes to choose how your foot presses effect the note on and note
off messages:
Normal - Stepping on a key sends a note on, releasing the key sends a note off. All
presets use this note mode unless otherwise noted in their descriptions.
Legato - Pressing on a key sends a "note on". When a different key is pressed, the
previous key’s note is turned off along with the new “note on”. If you wish to turn a note
off before hitting another key, tap on the select key.
Hold - This mode allows you to switch back and forth between normal mode and legato
mode using the select key (several older bass pedal boards use this mode). When you first
go to a preset that uses Hold mode the select LED will flash and the keys will be in Legato
mode. If you tap once briefly on the select key all notes will turn off, the LED will stop
blinking and the mode will switch to Normal. Step on the select key again and the keys will
go back to Legato mode and so on...
Toggle - Pressing a key sends a "note on", a second press sends a "note off". Stepping
on a different key sends a "note on" without turning off the previous key. Tapping briefly
on the select key will turn off all active keys.
12 Step uses Key Safety Modes. These determine whether or not stepping on one key
locks out all other keys to prevent accidental triggers:
Single Key - Only one key can be triggered at a time. While your foot is pressed on one
key all other keys are locked out and cannot be triggered. This helps prevent accidentally
triggering wrong notes. All presets use this mode unless otherwise noted in their
descriptions.
Multi Key - You can trigger multiple keys at the same time without any safety feature
implemented to prevent you from accidentally triggering another key.
12 Step MIDI Output
All presets unless otherwise indicated in their descriptions include the following MIDI data:
●
The ability to bend pitch is included and is mapped to the tilt source. Tilting your
foot up and down on the key activates pitch bend. The bend range is set to 2
semitones (note: synths may differ in the interpretation of the bend range).
●
Pressure information is sent out on MIDI CC #3. CC #3 can be mapped to a
parameter of your choosing on your synth.
●
The expression pedal is mapped to volume (CC#7) on all presets unless otherwise
noted.
