VCA
The VCA amplifies the VCF audio output thanks to the ADSR signal.
The MIX potentiometer allows to adjust the amplitude of VCO1 regarding VCO2 feed to the
VCF. (unless if the ring-modulator option is enabled, the MIX potentiometer mixes between
VCO1 and the ring-modulator).
Depending of the MOD MIX/VCA option, The VCA modulation potentiometer can modulate
either the MIX factor, ot the amplitude of the audio signal.
A master volume is also available.
Audio effect
You can choose one of the four available audio effects :
•
Distortion
WET : distortion amount. MOD : WET modulation.
•
Bit crush
WET : bit crush amount. MOD : WET modulation.
•
Delay
WET : level of audio sent to the delay line. It mixes between the VCA out and the delay line
out.
At 0%, the delay does not have any effect.
At 50%, the delay line input is a mix between the VCF out and the delay line out.
At 100%, no external sound is sent into the delay line. Only the delay line out is sent to the
delay line in.
MOD : delay time, ranging from almost 0 to more than 900ms.
Unlike the other effects, the delay is after the VCA in the audio chain.
•
Waveshaper
WET : Waveshaper amount. MOD : WET modulation.
Keyboard
When toggle is on NOTE, this is a 2 octaves keyboard controlling the frequencies of the
VCOs. It also controls the frequency of the VCF if “PITCH VCF” option is ON. The
portamento filters the frequency change of the keyboard.
When toggle is on MENU, the keyboard is used to patch the matrix and to edit all options.
