"Its strength is its drawbar hammond sound. It has 7-note polyphony and, like a real Hammond organ, nine variable drawbars (16, 8, 5 1/3, 4, 2 2/3, 2, 1 3/5, 1 1/3, 1). It also has variable percussive 2nd, 3rd, and 5th, with variable delay and sustain. The tremolo effect imitates a leslie rotary, with slow and fast speeds, and slow acceleration between the speeds. The ensemble effect is a rich chorus that makes the harmonics full, round, and rich.

I hastily and sloppily recorded some short audio demo snippets tonight which you can hear at:
gliss_ensemble.mp3
adding_16_8_5_4_2_1_with_tremolo.mp3
removing_8_5_4_2_2.mp3

It also has a monophonic solo section with a 3-octave keyboard range, but switchable to cover a total of 8 octaves with waveforms varying from sawtooth to square with modulateable pulse width and single lowpass filter with variable resonance and EG and/or LFO modulation.

An equally as hasty and sloppy and inadequate-to-fully-demonstrate audio snippet exists: boppling_solo_section.mp3

It also has a string section and poly synth section but they are not that impressive compared to its hammond sound. There are independent mono audio outputs for organ, polysynth, and solo sections, as well as a single mono output for a mixed output (all three)."
