A monophonic synth plugin that sends the sound from two sine oscillators through two sine waveshapers in series. You can control the vibrato, tremolo, portamento, the tuning of both oscillators, the oscillator mix, the shape amount (total and split over both shapers) and the phase of the second waveshaper function. There is also an ADSR envelope generator that can control the total shape amount and the amplification (with controllable sensitivity for both), an LFO for the total shape amount, distortion, and a feedback delay.

The shape amount and amplification is velocity sensitive, and the synth supports MIDI pitch bend events (with a range of +/- 2 semitones). All parameters can be controlled using MIDI Controller events.
