(10) VCF Cuto – controls the cuto frequency of the low pass lter.
(11) VCF Emphasis – controls the resonance of the lter.
Each of the voices of the Wave synthesizer is equipped with a 24dB per octave
voltage-controlled low-pass lter, based on the reproduction of the SSM2044 chip.
The VCF-Cuto knob sets the lter cuto frequency: frequencies below
this threshold pass unchanged, while frequencies above it are attenuated.
Turning the VCF-Cuto knob clockwise increases the cuto frequency, so when
the knob is turned fully clockwise, the sound passes unchanged.
The Emphasis control adjusts the lter resonance, emphasizing the frequencies
around the cuto frequency set by the VCF-Cuto knob. If the resonance is
increased signicantly, the lter will start to self-oscillate, generating a sine
wave whose frequency depends on the VCF Cuto. You can experiment the
eect of the resonance by increasing the Emphasis knob. Setting the emphasis
to values below 50%, produces the typical bright sound. Please note that one of
the characteristics of the SSM2044 is the dependency between resonance and
output signal level: as the resonance increases, the lter output level decreases.
The operation of the lter is depicted in the image below.

Filter Modulation
Filter Cuto frequency can be modulated by the following sources:
• • Pitch bend (Option BD in Digital menu)
• • Modulation Wheel (Option MF in Digital menu)
• • Low Frequency Oscillator (Option MF in Digital menu)
• • Keyboard (Option KF in Digital menu)
• • Velocity (Option VF in Digital menu)
• • Envelope 1 (Default)
• • Expression Pedal (Option EXP-PED in USER menu)
• • Channel Aftertouch (Option TL in Digital menu)

(12) Waves Osc – steps through the waveforms of the selected wavetable for the
main oscillator, from 00 to 63.
(13) Waves Sub – steps through the waveforms of the selected wavetable for
the sub oscillator, from 00 to 63.
If the selected waveform is a transient one (31-63) then controls

set the sample playback start points for the main and sub oscillators.
Waves Modulation
Main and Sub oscillator waves can also be modulated by:
• • Pitch bend (Option BD in Digital menu)
• • Modulation wheel (Option MW in Digital menu)
• • LFO (Option MW in Digital menu)
• • Keyboard (Option KW in Digital menu)
• • Aftertouch (Option TW in Digital menu)
• • Expression pedal (Option EXP-PED in USER menu)
• • Envelope 1 or Envelope 3 (Option SW in Digital menu)
