Focussed on the essential modules of a subtractive synthesizer Alpha 3 offers true hands on operation. Everything is where you would expect it, nothing is more complex than it needs to be. Nothing is less powerful than it needs to be. Alpha 3 is the sum of all our experience in synthesizer manufacturing.

Just when you are tired of the over-complex synthesizers of today, and when you want to return to the roots, the beginning of all synthetic sound, the times when a Synthesizer could be fully programmed, then the Alpha 3 is the right synthesizer for you. Get the synth that you can control.
