instructions
Each knob spins a position which can be accelerated or decelerated with a turn. This position is transmitted as USB-MIDI CC.
The position is converted to CC values according to the SHAPE.
- SHAPE = SIN – north is MAX, south is MIN.
- SHAPE = SAW – north is MIN, clockwise moves towards MAX.
CC number and MIDI channel are set within the parameters.
Hold the key to apply a friction brake to the spinning, slowing all down until they stop.
To edit parameters, short press and release the key. You’re now in the parameter editing loop:
MIN > MAX > SHAPE > FRICTION > CC > CH
Each parameter has a distinct visualization. Short pressing the key will advance to the next parameter. Note that you will cycle through each parameter in a loop.
To exit parameter setting, hold the key. You will return to play mode. Settings will be saved to flash and be recalled on next boot.
- MIN – this is the low value. Values 0-127 shown as 7’o’clock to 5’o’clock.
- MAX – this is the high value. Note that MAX does not need to be greater than MIN, they can be inverted.
- SHAPE – SIN or SAW as described above. Visualized as two-way gradient (SIN) and one-way (SAW).
- FRICTION – increase to add friction, slowing down rotation over time.
- CC – MIDI CC number, 0-127. Visualized by three “digits” from bottom to top: 0-9, 0-9, and 0-1. Ex: CC 25 would be position 5 on the bottom, 2 in the middle, with the top spot off.
- CH – MIDI CH, 1-16. Visualized as a bar, 1 on the bottom, 16 on top.
