Function Generator Modes
The Function Generators will respond to an incoming gate or CV signal differently based on the selected mode. There are
3 modes to choose from; Sustain Mode, Trigger Mode, and Loop Mode. Select the active mode using the [F1 or F2 MODE
BUTTON]. Enable or disable MIDI note on triggering the Function Generator by pressing [EDIT BUTTON ] + [F1 or F2 MODE
BUTTON].
Sustain Mode
Sustain Mode allows the function generator to act as a three stage attack (rise), sustain, release (fall) envelope, a slew
generator, an envelope follower. A gate or CV signal patched into the [IN JACK] initiates the rise stage, and the function
generator will increase over time to 5v. Once the function generator has reached the end of the rise stage, the output is
sustained as long as the gate signal patched into the [IN JACK] remains high. The fall stage is triggered once the incoming
gate or CV signal drops to 0v, and the function generator will drop over time to 0v. The envelope generated in sustain
mode can be retriggered at any time during the attack (rise), sustain, or decay (fall) stages.
The [END OF RISE GATE OUTPUT JACK] does not function in Sustain Mode.
Function Generators
Overview
The flexibility of voltage controlled Function Generators
allows them to serve many different purposes for sound
design. This includes envelopes, LFOs, slew generators,
envelope followers, and much more. The Voltage Lab 2
Function Generators can be intertwined for more
complex results using trigger conditions and a dedicated
mixer section offers four different versions of the
combined outputs.
Duration and Shape
A Function Generator is a variable modulation source
outputting between 0 and +5v. The shape of the output is
created using two main controls, [RISE KNOB] and [FALL
KNOB]. The [RISE KNOB] sets the amount of time the
Function takes to reach 5v and the [FALL KNOB] sets the
amount of time the Function Generator takes to return to
0v. These controls determine both the duration and
shape of the Function Generator. A short rise with a long
fall creates a saw-like wave. Matched rise and fall times
will generate a triangle. The rise time and fall time can be
modulated using the [RISE CV ATTENUVERTER] and [FALL
CV ATTENUVERTER] along with the [RISE JACK], [BOTH
JACK], and [FALL JACK]. The [RESPONSE KNOB]
determines the linearity of the Rise and Fall stages from
