I have never heard of this synthesizer so I'm guessing its a rarity, described as ".. may be the most complex patch over hard wire modular synthesizer ever conceived" in the world ever. (I added that bit). Completed in 1977 just as punk came in perhaps not the best of timings
A brief excerpt from the blurb:
VCOs are triangle core, not the traditional sawtooth core, and the sawtooth output tracks at twice the frequency of the other waveforms. The four stage envelope generators are not traditional ADSRs but operate more like 4 stage Serge DSGs, and can be put into recycle modes that track to trigger multiples. Dual VCAs are normaled pre-filters. The 822 Integrated Processing System is a massively complex array of filters and processing functions.
Thats why this one went for £9903.86
