Main Features

• 16-voice max polyphony (can be lowered, if desired)
• Notes per octave can range from 1 to 24 (the default is 12, obviously)
• Portamento and legato modes (can be used simultaneously)
• Smoothing control that affects twenty-one parameters and has a range of 0 ms to 1000 ms
• MIDI controller support: volume, panning/balance, pitch bend
• Includes sixty built-in factory presets designed by me (visit the Audio Demos section for samples)

Oscillators

• Two oscillators, with crossfade control
• Four waveforms (sine, triangle, pulse, saw), plus white noise and brown noise
• Individual stereo balance controls for each oscillator
• Stereo detune per oscillator from -100 to 100 cents
• Random intial phase controls for both oscillators
• Waveform shaping (or duty cycle modulation for pulse)
• Separate ADSR envelopes for each oscillator
• Osc 2's relative frequency can be adjusted using octave/semitone/cents controls
• Osc 2's phase can be freely adjusted at any time
• Hard, soft, and reverse sync modes for osc 2

Frequency Modulation

• Each oscillator is a carrier and has two modulators (the carriers are modulated separately then mixed together)
• Modulator 1 can modulate either the carrier or modulator 2
• Both modulators have their own octave/semitone adjustments
• Amount of modulation can be freely adjusted, per modulator, at any time
• Separate balance and stereo detuning controls for each modulator
• Separate ADSR envelopes for each modulator
• Velocity sensitivity mode: amount of modulation is influenced by note velocity

Filter

• Low-pass, high-pass, and band-pass modes
• Frequency and resonance controls, obviously
• Mode for tuning filter frequency to note frequency (every note is filtered separately)
• ADSR envelope

LFO

• Has the same four waveforms as the main oscillators (saw can be either upward or downward), plus white noise and brown noise
• Thirteen modulation targets (volume, pitch, balance, etc.)
• Waveform shaping
• LFO frequency can be synced to project tempo
• Controls for amount of modulation and modulation offset
• ADSR envelope

Envelopes

• Four-stage ADSR
• Attack, decay, and release times can range from 0 ms to 5000 ms
• Release slope shaping
• Envelopes are intelligent: if attack is set to 0 ms, that stage is skipped and the envelope begins at decay. If decay is also 0 ms, the envelope begins at sustain.
