- | 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.

Building is straightforward with all part values indicated (consider 33pF caps in place of 16pF). Start with the flattest components (resistors, caps, crystals, IC sockets) and work up to the higher ones. Ensure the DIN sockets are snug against the PCB before soldering caps all of the pins! Make sure resistor legs etc. don't inadvertently short out with metal parts such as the sockets and the crystal cans. | Building is straightforward with all part values indicated (consider 33pF caps in place of 16pF).
