24 About the Filter Envelope
Sequential
Env 1 Destinations:
•
filter
- Envelope 1 controls Filter Cutoff frequency
•
aux
- Envelope 1 functions as an auxiliary envelope that can be used
to modulate a destination selected through the Mod Matrix. The Aux
setting is available when Env 2 is set to
filter
+
amp
or
filter
+
gate
.
Env 2 Destinations:
•
amp
- Envelope 2 controls the Amplifier (loudness)
•
filter
+
amp
- Envelope 2 controls both Filter Cutoff frequency and the
Amplifier (loudness). Note that if the Env 2
velocity
button is on, it
affects only Filter Cutoff and not Amplifier volume.
•
filter
+
gate
- Envelope 2 controls Filter Cutoff frequency while
Amplifier volume is simply triggered (gated) on/off each time you
press a key on the Take 5 keyboard. Note that if the Env 2
velocity
button is on, it affects only Filter Cutoff and not Amplifier volume.
About the Filter Envelope
Routing Envelope 1 or 2 to the Filter shapes the harmonic characteristics
of a synthesized sound by giving you filtering control with each of the
envelope stages (attack, decay, sustain, release).
A filter envelope is one of the most important aspects of a synthesized
sound. Without an envelope, the filter would be static and unchanging. It
would stay open or closed by a fixed amount that wouldn’t change over
the duration of a sound. That’s not very expressive or interesting to listen
to — and it’s not how most real-world instruments behave.
In general, sounds produced by an acoustic instrument are brighter at their
beginning (the attack stage) and grow mellower as they die out (the decay
and release stages). In other words, their harmonic content changes over
time. This is exactly what the filter envelope is designed to emulate.
