Attempt at emulating the rare, strange and unique Crumar Spirit. It's pretty much all here but the arp. Standing in there is a simple step LFO.
The Spirit's dual filter is somewhat similar to Voyager; but the second is BP or HP and can have it's modulation and key-tracking disengaged for creating formant peaks.
It's two LFOs are unusual as well - 'Mod X' along with it's other waveforms offers the other LFO's output, and Oscillator B. The other, 'Shaper Y' is either an LFO with waveform continuously-variable Saw>Tri>Ramp or a 'one-shot' simple envelope.
The Spirit's unique dual mod wheels have been dealt with here by providing the ability to separately assign those two mod paths to the Wheel, Aftertouch, MIDI CC, or a panel knob for static settings.
The two rear panel jacks for control of Filter and Osc B pitch also have been implemented as MIDI CC selectors.
Special thanks to Martin Vicanek for help with the filter.
This does NOT emulate or model the actual sound of any vintage hardware synth, just borrows from the control design, layout and panel design of the Spirit.
32-bit, so will require jBridge, etc., (or a DAW that will bridge) for use on 64-bit systems.
The link on the website is to a Dropbox folder that also contains the .osm Synthmaker source 'schematics', so anyone with SM, or it's successor Flowstone, can alter it to suit. It's hoped that anyone who makes significant improvements will share the result with everyone.
As this was originally built for my own use only, there are no presets included; I wanted to come at the instrument anew each time, as one did with vintage analog hardware.
