ModMidi is a program that acts as an interface between the Mod Duo and the Behringer FCB1010. Here's what it does:

• Footswitches 1-5 switch between pedalboard presets
• Footswitches 6-10 load pedalboards from the current bank
• Switch 1 (Up) cycles through sets of 5 pedalboards on 6-10, if there are more than 5 pedalboards in the current bank
• Switch 2 (Down) is tap tempo
• The pedal lights & numeric display reflect the current state
• Everything stays in sync with the Mod Duo

Here's what you need:

• Mod Duo with my customized version of mod-ui (https://github.com/cdstouter/mod-ui/tree/modmidi-support) running on it
• Behringer FCB1010 with the EurekaPROM v3.2 chip set to IO mode
• A linux system with GCC & Docker installed

To compile for local testing on Ubuntu:

$ make

To compile for the Mod Duo:

$ docker build docker-modmidi
$ docker run -ti -v PATH_TO_MODMIDI_REPO:/tmp/ModMidi DOCKER_IMAGE_ID
(inside the Docker context)
$ cd /tmp/ModMidi
$ make

The compiled program can be run as-is. Try ModMidi --help for options. To install it on the Mod:

$ scp ModMidi modmidi.service [email protected]:~/
$ ssh [email protected]
(now we're in the Mod)
$ mount -o remount,rw /
$ mv modmidi.service /etc/systemd/system
$ systemctl enable modmidi
$ mount -o remount,ro /
$ systemctl start modmidi
