Based on the original synthesizer and circuit designs of Robert A. Moog, Tom Rhea, Jim Scott, and Crumar's Sante Crucianelli

Spirit has been significantly enhanced with expanded functionality and modulation options

Monophonic, unison, polyphonic (4, 8, or 16 voices), and cycle voice modes

Multi voice modes for unison, poly, and cycle that add per-note variation by adding three additional "mini synth" panels, each with their own pitch, pan, filter frequency, VCA Envelope Attack, and VCA Envelope Release settings

Quick-access multi-voice panel presets such as Hard Panned, Slightly Detuned, Well Worn, and more to simulate subtle or extreme variations between voices

Over 430 professionally designed presets in a dozen categories

Two oscillators with master tune, octave, waveshape, and oscillator sync

Oscillator B features modes to create a fixed frequency in two ranges – Bass and Wide – for drones, audio-rate modulation, or an additional LFO
