Crumar Spirit

Crumar Spirit Image

The Crumar Spirit was originally designed by Bob Moog (himself), 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.

For the hands-on approach, the Spirit is sure to please. There are 24 knobs, 10 switches and 15 sliders to start. There are 3 performance wheels for controlling the Pitch, Mod-X and Shaper-Y modulation effects (see LFO specs below). Using those with the Arpeggiator can get pretty wild. The Arpeggiator features 3 modes: Ripple (Up/Down), Arpeggio (Up several octaves) and Leap (Goes up 1 and then 4 octaves). There are also Auto and preset Glide modes for getting some elasticity or bending effects. Since all the LFOs, envelopes and filters are quite flexible you are sure to get some weird noises, fat basses, synths, etc. with the Spirit.

$1500 at most ? Wow, a guy here in the Netherlands is asking 3500 euros for one in pristine condition (non negotiable) !! That's $4,795!! Crazy. I'll try to keep an eye on it, see how he does and post back.

An incredibly versatile synth but as many have said, definitely not worth the inflated prices rip-off merchants are demanding on eBay!
Worth $1500 at the most considering the competition now on offer these days.
Also, it's not as if it's all discrete either.
We're talking CEM here people.

@henry I'd put my money on Cross Modulation.

Speaking of Atrax Morgue - Sickness Report, anyone knows a similar but less expensive/rare synth to make special sounds/noises like on that album?

Awesome synth! I wouldn't pay more than $1,000 US for one though.
I don't rely on e-Bay for current synth prices anymore. E-bay has been a great resource for buyers that don't have local access to synth resellers, but over the last few years prices on e-bay have skyrocketed to 1-2x more than what you'll find with a person-person sale or even through a collector. Vintagesynth prices do need an update as well, but people selling synths based on E-Bay prices are CHARGING TOO MUCH!! Too bad for the [beep] er that pays e-bay prices....
