Crumar Spirit
|
 General Info About the Crumar Spirit: The Crumar company was founded by Mario Crucianelli. In the early eighties he enlisted the help of Bob Moog and two of his employees, Jim Scott and Tom Rhea, and in 1983 they released the Crumar Spirit. The synth never caught on with the general public, and only between 100 and 300 were ever produced. Mine happens to be serial number 44. A special thanks to Joe Eberhardt for giving me the opportunity to buy it - I had never even heard of the Spirit before receiving his email. The Spirit is based on the famous CEM chips from Curtis. It contains dual CEM3340 VCOs, CEM3350 state-variable filters and CEM3360 VCAs. The synth has extremely complex audio and modulation routing, allowing it to make some truly unique sounds. It has dual oscillators, dual filters, dual modulators, dual ADSRs and 3 mod wheels, making it quite flexible. Another interestng feature of the Spirit is it's dual mixers and audio paths. One mixer feeds the filters, the second feeds a VCA controlled by the 'Shaper Y' modulation source. Lastly, the Spirit has Ring Mod, a noise source, external audio input and an arpeggitor.
