Crumar Spirit 1978i

The Crumar Spirit was originally designed by Bob Moog (himself), SERIAL 003 VERY RARE!!! Jim Scott & Tom Rhea and released back in 1983. It is a full featured analog monophonic synthesizer with 2 VCO's so it's got a pretty fat tone, but not as much as the classic 3-VCO Minimoog. However it is considerably more flexible than the latter. It has a basic 37-note keyboard without velocity or aftertouch. The two oscillators feature basic sawtooth, triangle and square waves and can be synced together.

The filter section is very nice featuring low-, high- and band-pass filters and switchable 12dB or 24dB slopes. Other features of the filter include an independent envelope with inverted and normal ADSR, key tracking and single or multiple triggering of the filter. Some other features of the Spirit include a built-in ring-modulator, an Arpeggiator with 3 different patterns and that can be linked to the LFO, and there's an external audio input for running external sounds through its filters, LFOs or Ring Mod.
