MIDINT

Maker	Fihdi
Type	8 channel MIDI to CV, gate and trigger interface with expanders
Mounting	Mixed
Width	6 HP
License	Proprietary (CC-BY-NC-4.0, noncommercial so not an open licence)
Difficulty	🔥 SMD (0805)

Four gate or trigger outputs and four CV outputs from a DIN-5 input, with trimmers for V/oct tuning so the CVs drive oscillators directly. Up to three expander modules daisy chain off a main module for 32 channels. Built around an Arduino Nano. Marked work in progress.
