Sync Nanoloop and LSDJ to MIDI (At the Same Time)

This setup lets one sync up to 6 copies of Nanoloop and 6 copies of LSDJ to MIDI clock signals. The circuit will respond to CLOCK TIMING, START, STOP and CONTINUE messages.

Schematic
Notes about the schematic:
• PORTD = digital pins 0 - 7
• PORTB = digital pins 7 - 13
• PORTC = analog pins 0 - 5
• PORTB = nanoloop sync
• PORTC = lsdj sync
• For each Nanoloop connection, the sync signal goes to the SERIN pin on the GB. The GND pin on the GB connects to Arduino ground.
• For each LSDJ connection, the sync signal goes to the CLK pin on the GB. The GND, SERIN and SEROUT pins on the GB all connect to Arduino ground. There is also a pull down resistor from the CLK line to ground. The value of this resistor is 22k up to around 100k or so.

Breadboard
Here is a breadboarded version with one Nanoloop sync out and one LSDJ sync out.
