Secure the Pico 2 to the 3D printed mount with M3 screws.

Insert the foot switch ground wire to a Pico 2 GND (black wire).

Each foot switch will have its output connect with a GPIO on the Pico 2. You'll start with switches 13 and 14, which are the MIDI Channel and Octave switches.

• Switch 13 to GP14 (green wire)
• Switch 14 to GP15 (yellow wire)

Foot switches 9-12:

• Switch 9 to GP10 (green wire)
• Switch 10 to GP11 (yellow wire)
• Switch 11 to GP12 (blue wire)
• Switch 12 to GP13 (white wire)

Foot switches 5-8:

• Switch 5 to GP6 (green wire)
• Switch 6 to GP7 (yellow wire)
• Switch 7 to GP8 (blue wire)
• Switch 8 to GP9 (white wire)

Foot switches 1-4:

• Switch 1 to GP2 (green wire)
• Switch 2 to GP3 (yellow wire)
• Switch 3 to GP4 (blue wire)
• Switch 4 to GP5 (white wire)

Insert the LED mount into the LED cutout. Secure the mount with its nut.

Wire the LED to the Pico 2:

• LED cathode to GND (black wire)
• LED anode to GP18 (red wire)

Insert the power switch into its cutout in the enclosure. Secure it with its nut.

Connect the power switch to the Pico 2:

• Switch L2 to ENable (white wire)
• Switch L3 to GND (black wire)

Run the MPM3610 and the wires connected to the DC jack through the DC jack hole on the enclosure. Then, run the assembly through the DC jack nut and the smaller ring.

Secure the MPM3610 to the 3D printed mount with an M2.5 screw and nut.

Connect the following wires from the MPM3610 to the Pico 2:

• MPM3610 5V to VSYS (yellow wire)
• MPM3610 GND to GND (black wire)

Insert the MIDI jack wires through the MIDI jack mounting hole. Run its wires through the ring on the 3D printed mount.

Connect the following wires to the Pico 2:

• MIDI jack pin 4 (current source) to 3.3V (red wire)
• MIDI jack pin 2/center pin to GND (black wire)

Finally connect the data pin from the MIDI jack to the Pico 2:

• MIDI jack pin 5 (current sink) to GP0/TX (green wire)
