g knob controls how fast the filter will move from the previous value to
the new random value once the input has passed the Threshold. The minimum set-
ting will cause abrupt transitions to the new random value and at higher settings the
filter will smoothly “ramp” to the new value.
ADSR Mode
ADSR Mode is a recreation of the standard envelope generator found on most syn-
thesizers. If you’re new to synthesis technology, ADSR stands for Attack, Decay,
Sustain, and Release, which also happen to corresponds to the four knobs of this
mode. Funny how it works that way!
With the ADSR you can define a specific envelope shape that will be used to modu-
late the filter each time it receives a trigger
based on the level of input signal. This
is quite a bit different than the Envelope mode whose shape changes and responds
dynamically to the input signal
On a keyboard synth, the ADSR envelope is triggered each time you press a key. In
FilterFreak, the “ADSR” is triggered either by pressing the T
