This store is temporarely paused. I have transitioned to sell through retailers, so I can spend more time building and less time shipping. I appreciate all your support.

Note: Modules are now available through retailers.


This module allows you to do many things, but in essence, it is just a bunch of oscillators that never go out of tune or out of scale! Apart from playing anything between lush pads and hellish walls of sound, it enables you to easily jam with other musicians and explore characters of different scales. If you don't know any music theory, don't despair, the module will do all the harmony maths and all left for you to do is to use your intuition. If you, on the other hand, understand the basics of music theory, with this instrument, you can leverage it.

Note that this is a eurorack module, not a complete synthesizer. It cannot be used without a case and a power supply.
