turning ‘off’ when the signal goes below. At lower gain settings the envelope follower
will be more touch sensitive and dynamic.
Attack
The A
Atttta
ac

k knob controls the how fast the filter will react to an increase in signal
level. A fast setting will cause the envelope follower react very quickly to transients,
and will produce a very dynamic, staccato-like filtering effect. Setting the Attack
knob to a slower setting will smooth out and lengthen the attack response the enve-
lope follower. The filter will behave like it has had a few too many beers!
Release
The R
Re
elle
ea
as
se
e knob controls how fast or slow the filter will react to the input signal as
it decreases (the opposite of the Attack knob). Again, a faster release setting will
produce a more dynamic effect, and slower release times producing a slower,
smoother effect as the sound decays.
Random S/H Mode
The Random S/H (Sample and Hold) Mode produces a waveform that jumps from one
value to another at each cycle. This effect was used (and abused by ELP) in the
beginning of Brain Salad Surgery, you know…“Welcome back my friends to the
dinosaur that never ends” as well as other cheesy sci-fi movies to mimic the sound
of bleeping and burping computers. However, it is still a cool effect and FilterFreak
offers a few twists so that its sample and hold can be synced to the tempo of your
music.
Tempo
As before, you can either use Tap Tempo to define the BPM of the random signal or
sync it to Midi Beat Clock. When using MIDI beat clock the display will show the
current tempo. Use the Tap Tempo as previously discussed.
