Dream Emplant Wasp (1978)

 

Portable analog synthesizer (but digital oscillator) similar to Electro harmonix Mini-Synthesizer or EMS synthi.

Fun plastic analog machine with great design made in the UK (Oxford) during the seventies.

SYNTHESIZER keyboard 25 keys is is based on conductivity generated by fingers. The main panel features a small speaker, 18 knobs and 5 selectors.

Front terminal connectors are:
- signal line out
- headphones out
- 7 DINS used to link other units to the synthesizer like the SPIDER sequencer which is not compatible with standard Midi system.

Power supply is a 9V external PSU or 6 X 1m5V batteries-

STRUCTURE monophonic structure: 2 digital oscillators based on a master 250 kHz oscillator and 2 timer NE-555.

 

 

OSCILLATOR description:

OSC1 OSC2 octaves 32' 16' 8' 4' 2' 32' 16' 8' 4' 2' waveforms saw / pulse saw / pulse variable pulse width yes - detune - 12 semitones volume mixer - -

PERFORMANCE 2 main functions:

blend knobs allow the keyboard's tuning while master tune can be set on the frontal trimmer glide function set the portamento time for special legato play.

LFO a single bipolar modulator (shapes: sine, saw up, saw down, square, noise and random) and 2 destinations:

- LFO to VCF cutoff - LFO to OSC1 & 2 pitch

 

FILTER VCF is resonant (but not self-oscillating) and features 3 modes:

- lowpass - highpass - bandpass

 

ENVELOPE 2 EGs share same 3-segments ADS structure:

- EG1 VCA amplitude - EG2 VCF cutoff Sustain stages can be set also to REPEAT mode which engage the EG repeat function.

 

MAINTENANCE

the keyboard is highly unreliable and often needs overhaul (pictures thanks to TOPOPICCIONE ) click to enlarge
