RK-004 Raspberry Pi Image

Buy the RK-004
For the tinkerer; We’ve released the RaspberryPi image to add MIDI-Host functionality to the RK-004. You can download the image on google drive (source code is included).

If you want to use the RPiZero as a USB Host or USB midi interface with the RK-004 you can download this image

You can burn it onto an SD-card with the following programs:
ApplePi Baker
use the dd command or Etcher

Connecting the RPi to the RK-004 requires only 4 wires. The RPi Board will be powered from the RK-004. The PiZero will bolt right in with a straight connector but you can also use a flatcable to make the connection. Below is the pinout of the connector (the upper one with serial signals is for the RPi):

Note that this connector is not just for the RaspBerryPi. Although this is the platform we have released the code for, you can connect any board with serial I/O to it (arduino, etc) and communicate with your music gear.

For RPi’s which are already running a system you can add our repositories like shown in this video. You can connect the RK-004 via the RPi serial port and it will show up like a MIDI port on your system:

curl -sLS https://www.retrokits.com/debian/add.sh | sudo bash

sudo apt-get install rk004d

and reboot.

Our daemon has a built in midi monitor you can view from the terminal with command:

tail -f /tmp/rpirk004midimon
