Designing over 300 instruments will teach you a thing or two about user experience, interface design and ergonomics. In this interview, Girts Ozolins from Erica Synths, discusses the details that make an electronic instrument interactive and performable.

We talk about the research that goes into synth design - first, figuring out the user experience, and then the electronics to make it work. An approach that helps make design decisions efficiently and professionally.

Instruments we cover include Joystick II, Black Sequencer, Zen Delay and the Fusion Eurorack series. But we also touch on Girts' favourite mouse. Check out the images below for some early sketches that lead to the final designs.
