Each voice offers two oscillators, a sub oscillator and a noise generator, two filter modules,
one (resp.two) amplifier modules and an internal effect processor. 3 LFOs and 2 envelopes are
used for modifying the behaviour of the audio modules.

The two main oscillators feature sawtooth, pulse with pulse width modulation or
one of 60 digitally stored waveforms that cover a wide range of typical FM, additive and analog
sounding timbres. The blend ratio of sawtooth to pulse or sawtooth to the selected waveform is
modulatable. The sub oscillator generates a square wave that is one octave lower than oscillator 1.
Oscillator 1 can synchronize or frequency modulate oscillator 2.

The two filter modules each offer low pass, band pass, high pass and band reject, all
with resonance and can be set up in four different routing modes, described below.
The signal output of filter 1 can further be modified with a signal shaper offering four different
distortion / shape curves.

Filter routings:
-Standard cascade filter type where both filters are connected serially.
-Parallel connection where the oscillator and noise sum are routed through both filters.
-Parallel connection where oscillator 1 and the sub oscillator are routed through filter 1 and
oscillator 2 and noise are routed through filter 2.
-Parallel connection where all oscillators and the sub oscillator are routed through
filter 1 and only noise is routed to filter 2.

A third LFO, which can be accessed through the display and the data entry knob, is available
for pitch vibrato. All parameters are accessible thru MIDI control change messages to give
you full real time control.
