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

Alpha 3 allows Frequency Modulation of the Filters Cutoff, a feature only found in very few Synthesizers. The source of the Filter FM can be any oscillator, even noise. Together with the Ring Modulator which can be gradually morphed from pure Oscillator 2 over Amplitude-Modulation to Ringmodulation this is a guarantee for some of very finest and most exotic sounds a classic subtractive synth can produce.
