GUMS is software for configuring, composing, and performing with hardware (synthesizers and controllers) regardless of their data protocol. The video below demonstrates connecting a Lumatone MIDI controller to a Eurorack modular synthesizer, and goes over the software’s core features, such as adding and configuring MIDI nodes, setting up the data flow and connecting nodes together, processing audio inputs, using both CV and CC messages to change parameters, and saving and loading configurations. Additionally, the sequencing capabilities are demonstrated by recording a short piece, playing it back, and accompanying it in real time. GUMS is written entirely in the ChucK programming language.
