Fade-In
One more feature of the LFO module is the possibility to add a fade-in effect to its output signal.
The duration of this fade-in can be adjusted within the range of 0 to 5 seconds, as determined by
the
Fade knob. Turning this knob fully to the left results in a value of 0 which is equivalent to
removing the fade-in effect. The time at which the LFO signal is introduced can even be controlled
by adding a delay to the fade in. This parameter can also be set to values varying between 0 and 5
seconds, as determined by the
Delay knob. Note that this knob is effective even if the Fade value
is adjusted to zero. In this case, the signal from the LFO module si simply delayed.

Modulation Destinations
The signal from the LFO module can be used to modulate parameters in the VCO , Filter , and
VCA modules using the controls located on the left part of the module. Available modulation
destinations on the VCO module are the cutoff frequency and pulse width parameter controlled
with the VCO Detune and VCO PW knobs respectively. The Filter Freq and Filter Res knobs are
used to control modulation of the cutoff frequency and resonance of the Filter module. Finally the
VCA Gain and VCA Pan knobs are used to control the modulation of the gain and panning of the
VCA module.
5.3.6 The Envelope Module
Each row of Ultra Analog VA-3 is equipped with two envelope generators, the Filter Env and Amp
Env modules which are used to modulate the Filter and Amp modules. Both envelope generators
have the same user interface and offer the same functions. Envelopes are generated through the use
of a standard ADSR (attack, decay, sustain, release) approach including MIDI velocity modulation
and looping capabilities.
