uSEQ is a eurorack module that brings livecoding into your modular system. Fundamentally, it’s an extremely flexible voltage generator and processor. It has a set of CV and pulse inputs and outputs, but instead of having a fixed set of controls and functions, you can choose how voltages are generated by livecoding them. This means that you can control uSEQ’s behaviour with the vast possibilities of creative coding, using a simplified programming language specialised for music. uSEQ is great for sequencing, waveform generation, and waveform processing. You can use it as a live performance tool, or configure it for specific functions.

To use uSEQ, hook up a computer via the USB port, load up the editor in your browser and start playing.
