MU53

Simple, immediate, and a little unp°edictable.

Introducing the MU53, our take on a dual oscillator supersaw virtual analog synthesizer. We took cues from retro synth designs and added some ideas of our own. We wanted to keep MU53 simple and immediate - twist a knob, hear the change. No menu diving here.

About MU53

MU53 is our take on a dual oscillator supersaw virtual analog synthesizer. Inspired by old school analog synthesizer design, it has a simple and direct set of per-knob controls that get out of your way quickly so that your creativity can flow. MU53 can be a little quirky and maybe even unpredictable... but that's where the fun is.

Our goal with MU53 is to make a synthesizer that is easy to use and easy to get to the sound that will inspire you to make your music.
