EDP Wasp


Released: 1978



Basic dual oscillator monosynth with odd capacitive keyboard and proprietary digital interface. Architecture Class: Conventional (subtractive).

Ebay Description:

The EDP Wasp is a 25 capacitive key monophonic synthesizer, featuring a dual oscillators (pulse, square, saw waveforms), white noise, a resonant 12dB low|high or 6dB band-pass filter, an LFO (sine, saw:up|down, square, noise, or random waveforms), dedicated (AD) filter and (ASR) amp envelopes with repeat, 7 pin DIN port, and portamento (glide).
