The 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 range of 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 have been replaced with a dual-digital oscillator built on the Mitsubishi M16C.

The Pixie expands the original WASP by adding the following extra functions:-

1. Additional waveshapes on both DCO's (Triangle, Sine and Modulated Square)
2. 2nd WASP Filter
3. Low-Pass Filter
4. Ring Modulator
5. 4-channel pre-FilterMixer
6. 4-channel pre-Output Mixer
