- | Trivial combination of four I2C modules for four MIDI outs. It differs from the previously designed Quad I2C MIDI in that the connectors are on convenient 2*5 IDCs, and the BLM port is moved over to the [[wcore_midi8|MIDI8 module]] If somebody wants to code it, the ADCs onboard could also be used. | + | Trivial combination of four I2C modules for four MIDI outs.
