F.A.T.

The Freebass is a 100% analog module, but it benefits from employing the latest in component technolgy.

It features a VCO that is continuously variable between Square and Sawtooth waves (this was not available on the original 303) and in addiiton to this controls for filter cutoff, resonance, envelope mode, decay and accent (this much loved feature of the original 303 is now triggered by a MIDI signal and has an influence on the the envelope, volume and cutoff frequency of the sound).

The Freebass also has a dedicated auto-tune facility and in addition to all of this the unit features an audio input to the filter.
