IN-DEPTH LOOK AT THE RSHMOD (R SHMOD) FUNCTION.
This alters the shape of the release envelope, allowing you to fine-tune the release
behavior to adapt it to any audio source.
Shape modulation on release allows the detector’s attack curve to be deformed based
on curves sampled from the most powerful software and hardware compressors. Spe-
cifically, values below the middle position tend to increase pressure at the expense of
distortion and color. In contrast, higher values tend to reduce pressure for less harmonic
distortion and more transparency but with a more significant pumping effect and less
compression.
Generally, minimum RSHMOD positions reduce release times to one-tenth of their no-
minal value, while in the opposite case, they tend to quadruple it. In the case of a minimal
setting, if the release knob setting is also minimal, there will be a null/instantaneous time
(also corresponding to values less than a microsecond, depending on the oversampling
value set).
The positions above the middle of the knob stroke are of particular interest: from the
center to 3/4 of the stroke, the amount of HOLD of the release gradually increases. In
an envelope detector, the release is the time required for the circuit’s output to reach
the input signal’s minimum value after a sudden decrease in its amplitude. On the other
hand, the hold function forces the time required for the output of the circuit to maintain
its constant value after a sudden decrease in the amplitude of the input signal. This
tends to stabilize the compressor action, creating less harmonic distortion and making
the compression action less aggressive and ineffective.
In the case of Tiger, the HOLD time is also proportional to the current release value. The
release-related HOLD function differs from the attack-related HOLD function because it
is independent of the threshold.
