Electronic Dream Plant WASP

    Description
    The Wasp was undoubtedly EDP's most famous product, distinctive for its black/yellow colour scheme and brittle construction. It was notorious for its lack of a mechanical keyboard; instead, it used flat conductive copper plates, hidden under a silk-screened vinyl sticker. This was claimed by some to be unreliable, unintuitive, and devoid of much of the expression present with a real keyboard. Despite these flaws, the Wasp was in fact fairly advanced technologically.

    It was one of the first commercially available synthesizers to adopt digital technology, which at the time was just beginning to become a standard. It also utilized a proprietary system for connecting several Wasp synthesizers together, predating the invention and standardization of MIDI by several years. The digital interface should not, however, be confused with MIDI, even though similar DIN plugs are utilised (7-pin DIN instead of the 5-pin DIN which MIDI standardized to).

    Architecturally, the wasp is a dual digital oscillator synth, with dual envelopes and a single, switchable (low/band/highpass) CMOS-based filter.

    Official Product Description:

    Electronic Dream Plant proudly presents the "WASP:' a new concept in synthesiser design. For the first time a synthesiser is brought within reach of everyone's pocket.

    KEYBOARD-a touch sensitive, two octave keyboard incorporating a new digital breakthrough which holds the oscillators constantly in tune. This means no tuning worries halfway through a gig.

    OSCILLATOR 1-a sawtooth, pulse and width control with a range of six octaves.

    OSCILLATOR 2-sawtooth and square wave with variable pitch control the same octave range (pitch bending facilities and glide control operates the two oscillators-but just hear the difference!).

    CONTROL OSCILLATOR - control outputs for square, sine, sawtooth (rising and falling), noise and random sample and hold Frequency and pitch modulation controls, NOISE-separate volume for signal output.

    FILTER-fully comprehensive filter which tracks constantly to the keyboard. The filter consists of frequency and 'Q' controls on low pass, band pass and high pass. The controls to the filter are accessible from both the control oscillator and second envelope (these controls are reversible).

    ENVELOPE GENERATOR SECTION-the signal generator contains separate attack, decay and sustain level/repeat controls-the release is governed by the decay knob. These are totally independent from the control envelope which consists of separate attack, decay and delay/ repeat controls. The delay function means that a delay time can be set up to one second after triggering the keyboard.

    OUTPUTS - a master power off/ volume output. Jack sockets for line out and headphones. Two line sockets for interconnection of up to fifty "WASPS:' this unique design feature means that by connecting two or more "WASPS" together, any keyboard can control all connected "WASP" voices.

    SPEAKER-a small speaker is built into the "WASP!' This speaker is disconnected when the line out socket is in use.

    POWER-the "WASP" runs off six IC' size batteries or a 9v mains adaptor for which a socket is provided.

    HOUSING-the entire workings, including the touch sensitive keyboard are incorporated in one single circuit board which is housed in unbreakable plastic.

    Each "WASP" is accompanied by an easy to follow handbook. We feel sure that when you see and hear the "WASP" you will agree that for its astoundingly low price this makes a very attractive package.
