An other day : the MIDI to CV/GATE is built

The processor is programmed and the different voltages have been checked. The precision seems good. The maximum error observed is less than 4% and seems to be on average less than 1% :


It only remains now to test this interface on a VCO / VCA module to check its behavior in situation.

This interface has 8 CV / GATE outputs. Four CV outputs are in 0 ~ 5V, four other outputs are in 0 ~ 10V. Each output is available on a MIDI channel from 1 to 8 or 9 to 16 depending on the position of the selection switch.

On the production board, it will be possible to choose the maximum voltage of all the outputs by setting up the appropriate resistors, 5V max or 10V max.

The GATE outputs are 0 / 5V.
