If this seems a little complicated, the best way of remembering how lo and hi work is that a lo curve
spends more time near the lo value of volume, while a hi curve spends more time near the hi value.
The higher the number i.e., Lo9 rather than Lo1, the more pronounced the effect.
To get even more control, these curves can be combined so that the curve starts as a “lo” curve, but
ends as a “hi” curve (Lh-), and vice-versa (hL-). The Lh- curves are particularly useful for volume
fades: note how the change starts and ends smoothly at both ends. These curves, also known as
sigmoid curves, allow the most natural-sounding fades to be achieved.
The Voluum lets you do super-smooth volume fades that would be impossible to achieve using a
simple volume pedal: enable FAd (set to on) and set a fade time using the tiM parameter. When the
footpedal is moved to the toe-down position, the volume will fade from lo to hi. Conversely, when the
footpedal is moved to the heel-down position, the volume will fade from hi to lo. You can use this to
make a signal fade quickly or very slowly to get the effect that you like.
When you select envelope control for the volume effect, a level-triggered
ADSR
(attack-decay-
sustain-release) volume envelope is applied to the signal which gives you automatic volume swells
and lets you create synth-like sounds. The
ADSR
envelope parameters attack (Att), decay (dEC),
sustain (SuS), release (rEL) and threshold (thr) control the
ADSR
volume envelope. They are shown
in the figure below.
