Python-based, open-source library and command-line tool to control the Steinberg UR44C Mixer and DSP.
Probably will work with other models like UR22C, UR24C, and UR816C with minor changes; however, I can't test because I don't have such equipment.
The goal of this project is to replace dspMixFx, as it is not available for Linux and also doesn't work under Wine.
The UR44C has two MIDI ports available via USB: the first one is physical MIDI interface, and the second one is internally connected to the Yamaha Mixer with DSP for control purposes. When no drivers are installed, the device works in Class Compliant mode, and both MIDI ports are available in the system. But after installing official drivers, the second port becomes hidden, and only the proprietary dspMixFx application can access it.
The Mixer is controlled by SYSEX messages with Yamaha manufacturer identifier and common Yamaha SYSEX message structure.
Currently, only a few protocol messages are recognized. If you want to recognize more, you may be interested in preparing the following setup:
sudo modprobe usbmon)mixer-control-protocol.lua into the Wireshark Global Lua Plugins folder (you can find the path in Help > About Wireshark > Folders)This software is developed for research purposes only.
