5 - Effects
Core Effects Descriptions
Attack, Decay and Release times are all adjustable, and the shape of each of these
segments is selectable between exponential, linear, or logarithmic. An additional Hold
Time can be used to extend the Sustain phase past the point where the signal has
passed the Release Threshold.
If the Sustain Level is set the same as the Release Level, then the Reshaper effectively
becomes a two-phase "transient catcher" where the Release Threshold, Hold Time and
Release Time are ignored.
While the peak Attack gain level is always fully turned on, note that the Release Level is
not necessarily completely off, but can be adjusted upward so that the Reshaper retains
a nominal minimum gain. This allows the Reshaper to resculpt only the louder
transients of a signal while maintain a nominal output signal level the rest of the time.
The Release Threshold is always expressed relative to the Attack Threshold so that they
will automatically track each other when the Attack Threshold is adjusted.
Parameter Description
Attack When the input signal rises above the level set by the Attack
Threshold Threshold parameter, Reshaper's ADSR engine begins the Attack
phase. The turn-on threshold is adjustable anywhere between
-40dB and 0dB (below the PatchMix nominal operating point of
-12dBFS.)
Attack Time This parameter controls the time, in milliseconds, that is required
during the Attack phase for the gain rise from its quiescent Release
Level to unity gain, or 0dB.
Decay Time This parameter controls the time, in milliseconds, that is required for
the gain to fall from 0dB down to the attenuated Sustain Level.
Note that if the Sustain Level is set to 0dB this decay time becomes
simply a delay before entering the Sustain phase.
Release Time This parameter controls the time, in milliseconds, that is required for
the gain to fall from the Sustain Level down to the Release Level.
Level Meter This meter represents the input signal level in dB, and is in fact the
output of the Gate's envelope follower. Since the envelope follower
is driven by the greater of the left or right channel, this
monophonic meter represents the greater of the two input signals.
Sustain Level This sets the gain level applied to the input signal when the ADSR
engine is in the Sustain phase.
Release Level This sets the final gain level applied to the input signal when the
Release phase is fully decayed. When set to the minimum (-70dB)
the effective Release Level is -infinity, i.e., fully turned-off.
Hold Time This parameter allows additional time to be added onto the Sustain
phase after the input signal falls below the Release Threshold before
transitioning to the Release phase. This extension of the Sustain
phase is useful for altering the tail dynamics of the sound.
