Pin numbering

For CV inputs and outputs these map directly onto the analog inputs and outputs of Bela. The same goes for the Audio input and output.

When it comes to the digital elements of Bela the pin numbering is a bit less orderly but here's a guide to the LED, Buttons and Trigger inputs.

LED output pins are as follows from left to right:
PD: 17, 18, 21, 13, 14, 11, 12, 15, 16, 19
C++ / Supercollider /Csound : 6, 7, 10, 2, 3, 0, 1, 4, 5, 8

Button input pins, left to right:
PD: 26, 25, 24, 23
C++ / Supercollider /Csound : 15, 14, 13, 12

CV IN 4 through CV IN 7 jack sockets can be configured via jumpers so that they are connected to digital inputs in parallel with the buttons. See pinout of buttons above.

V1 of the board has slightly different pin numbering:

CV 4 -> pd: 22
CV 5 -> pd: 20
CV 6 -> pd: 23
CV 7 -> pd: 24

Button 1 -> pd: 25
Button 2 -> pd: 26
