The Pixie is a clone of the WASP that keeps the salient features of the WASP but replaces the keyboard circuitry with a MIDI interface to provide a more flexible product. Also, to improve the stability of the design, the two 555-based VCOs and associated decoding circuitry have been replaced with a dual-digital oscillator built around the Mitsubishi M16C.
The EDP Wasp was a quirky little synthesizer that, despite its toyish look was quite capable of funky analog types of sounds. Under the hood the Wasp was a real surprise! It was actually a very early DIGITAL synth that also happens to sound great! With ANALOGUE filters, envelopes and controls, the Wasp offered flexible and traditional synthesis of cool bass, synth, and other useful monophonic sounds. It was used by 808 State, Dave Holmes, Vince Clarke, WhiteHouse and Add N to (X). It's designer, Chris Hugget, also designed the Oxford Synthesizer Company's OSCar Synthesizer.
