Control the Jamulus Mixerboard using MIDI

This guide explains how to setup your system in order to control the Jamulus Mixerboard using a MIDI Control Surface device (or similar) using JACK. In this article Windows is used as an example, however it will be possible to perform this on other platforms as well. For Linux, the process will be very similar as this platform also uses JACK. You will need to install an extra component (like a2jmidid) to allow the midi device to connect to JACK. For macOS you can use MIDI Studio to ensure the midi connection is linked properly to Jamulus.

Get computer audio into Jamulus

This guide explains how to play a mp3 file, YouTube video, MuseScore file or any system audio into Jamulus. We’re using JACK for Windows however, it is also possible to use different software like VoiceMeeter Banana, ASIO LinkPro or similar. I assume you already know how to install software or know someone who helps you with that.

Jamulus related projects

This document lists a number of third-party projects related to Jamulus that you may find interesting. Certainly it is not an official list of officially supported projects.

Multiple Inputs

Points to note about inputs

• If you want to connect 2 or more sources (e.g. voice + synth + guitar), it is important to note that Jamulus currently handles only 2 input channels (L/R). So the hardware being used must provide a mixed-down stereo output to Jamulus. Alternatively, run two instances of Jamulus, if your hardware supports it, or use virtual audio inputs to Jamulus for each hardware input.
• Audio interfaces generally output a mixed signal on their analogue output, but separate signals (1 per source) on their digital output (USB/FireWire/Thunderbolt).
• Mixers generally only output mixed-down signals on their analogue output.
• Mixers with USB/FireWire/Thunderbolt generally output a mixed-down signal on their analogue output AND separate signals only (no mixed-down signal) on their digital output.
• A few Mixers with USB/FireWire/Thunderbolt will either send only a mixed-down signal to the digital output (small/budget mixers), or else also ADD a stereo mixed-down signal to the separate signals on the digital output.
