● ATTACK sets the time the envelope takes to rise from zero to maximum after a note
is played.
● DECAY sets the time the envelope takes to decay from maximum back down to the
level set by the SUSTAIN.
● SUSTAIN sets the level the envelope maintains after the decay stage has finished.
● RELEASE sets the time the envelope takes to decay from its current level back down
to zero when a note is released.
The FI has three dedicated envelopes which control the Voltage-Controlled Amplifier (VCA),
the Voltage-Controlled Filter (VCF) and the Noise Generator respectively. The VCA and VCF
envelope generators have three different modes (VINTAGE, ADSR in RESTART and ADSR
in RESET-TO-ZERO) which are selected using the Envelope Mode slider.
Moving from left to right, the sliders of the Envelopes Block are as follows:
●
ENV MODE (VINTAGE/RESTART/RESET):
Sets the behavior of both the VCA and VCF envelopes as described below.
●
VCA A/(D)/(S*)/R (1...127):
Changes the volume of the synth signal coming from the VCOs dynamically over
time.
●
VCF A/D/(S*)/(R) (1...127):
Changes the cutoff frequency of the filter dynamically over time.
●
NOISE A/D (1...127):
Changes the volume of the noise source dynamically over time.
* The sustain stages of the two ADSR envelopes actually start their range from 0.
Note:
The VCF and NOISE envelopes can be freely assigned to many other parameters
when used as a control source with a Flexi Controller. (See the section on
below for a detailed explanation.)
