the MOD Duo is a guitar/instrument pedalboard made by the company Mod Devices, which has the following features:

• Open-source firmware based on Linux, Jack, LV2 standard.
• Web client served by the pedalboard itself via WIFI or Bluetooth
• Two independent inputs and outputs. Supports any signal chain in between.
• Ability to create or build your own effects.

This project is about building the software components on openSUSE, with the following goals:

• Learn how it works
• Contribute to it
• Evaluate it before buying the hardware
• Experiment: eg. make a simpler pedalboard with a RaspberryPi and a DAC.

Status

• mod-host and mod-ui built here.

mod-ui running on openSUSE:

How to run it

sudo zypper ar obs://home:dmacvicar:mod/openSUSE_Tumbleweed modduo

# install qjackctl and friends
sudo zypper in a2jmidid qjackctl jack

# install mod duo software
sudo sudo zypper in mod-host mod-ui

# install some effects
sudo sudo zypper in lv2-calf lv2-guitarix

Now, configure QJacjCtl to start mod-host at startup of jack:

Go to Setup -> Options

[X] Execute Script after Startup: [ a2jmidid -e & mod-host ]
...
[X] Execute Script on Shutdown: [ killall a2jmidid mod-host ]

Edit the mod-ui port:

sudo vi /usr/lib/python3.6/site-packages/mod/settings.py

Change the port to a non-root port:

DEVICE_WEBSERVER_PORT = int(os.environ.get('MOD_DEVICE_WEBSERVER_PORT', 8082))

Start jack with QJackCtl Now start mod-ui:

mod-ui

Go to http://localhost:$port in your browser.
