The EDP WASP Revisited
The original EDP WASP
The Mk 1 Pixie
The current Mk2 Pixie Attache
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 ANALOG filters, envelopes and controls, the Wasp offered
flexible and traditional synthesis of cool bass,
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.

Pixie Attache is a revisit 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, giving the user access to a wide
MIDI controllers including
keyboards, laptop/PCs and iPad's.
To help improve the stability of the design,
the two 555-based VCOs and associated decoding ciruitry
a dual-digital oscillator built on the Mitsubishi M16C.
