Sound Features

Curve features aliasing-free oscillators with custom waveforms, noise generation and broad FM options. Waveform crossfades provide for changing timbres; a comprehensive unison mode delivers fat lead sounds, wide pads and massive sound.

Flexible filter routing, a feature-rich mono mode plus legato and glide, are all designed for great depth of control.
