"Fitted with a custom delay circuit which is tailored to creating, in addition to conventional delay effect, drifting abience, glitch and abstract sounds through to harsh industrial noise. The synth also contains a fully analogue custom resonant filter similar to those found in the MS20. This turns the keyboard into a versatile digital/analogue synth hybrid capable of creating sounds of a quality comparable to many old synths from the 70's & 80's. The combination of delay, VCF and LFO allow for a huge spectrum of sounds to be created."
