Custom VJ Macro Pad (Raspberry Pi Pico)

These are instructions to build a macro pad for the Immersions VJ app on the iPad.

Get the app for free on the App Store.

Project homepage: Immersions VJ

Hardware

• 1 Raspberry Pi Pico (about 5 euros)
• 1 Pico RGB Keypad Base (Pimoroni, about 20 euros)

Installation

Instructions: pmk-circuitpython

They are easy. Here are the libraries you should have installed on your Pico at the end of the process:

• adafruit_hid
• pmk

Customization

Upload the code.py file to the root folder of your Pico.

The code:

• Assigns a function to each key (either when it is pressed once or continuously)
• Sets colors customised for the Immersions VJ app
• Animates key colors to reflect their function in the app (e.g. quick flashing light to increase bpm)

Future improvements:

• Update pad colors based on the theme and status of the app
