(like in triangle or saw), to a jump (link in a square), passing throw a sinusoid shape.
The other fader (SYM) adjust the symmetry of the output, i.e the ratio between rise/fall time.
This fader allow to pass from a rising saw to a triangle and then a falling saw.
The frequency range of this LFO is very slow : it can shift from about 100s for very slow
sound evolution to about 20Hz.
This LFO also admit a modulation fader in order to generate complex waveform. This
modulation act like the oscillators modulation. You can choose the modulation source,
modulation algorithm, and the fader adjust the modulation amplitude.
Like the oscillators, the LFO modulation have been tuned to give interesting result when
acting in auto-modulation (selecting the LFO as the LFO modulator).
ADSR
This is a standard analog type ADSR :
Attack, Decay and Release time, as well as sustain amplitude can be adjusted with 4 faders.
The ADSR is triggered by a GATE signal.
Depending on the configuration, the GATE signal can come from :
•
The Keyboard
•
A MIDI note
•
The LFO (when it’s signal is high)
•
The audio in (when the amplitude is high)
in “ON” mode, the ADSR is not used by the VCA. The audio signal is amplified by the VCA,
but the ADSR can still be trigged by a note to generate modulation data.
MIX
The MIX fader allow to adjust the amplitude of the 4 oscillators.
Depending on the audio out option, this mix can be :
•
Mono : The signal is the same on the Left and Right out channel.
•
Mix : OSC 1 is louder on the Left channel, OSC 2 and 3 are centered, OSC 4 is louder
on the right channel.
•
Stereo : The OSC 1 and 2 are routed to the Left channel, 3 and 4 to the right channel.
VCA
The dual VCA is connected to amplify the MIX outputs thanks to the ADSR signal.
