•
[ATTACK]
(Attack Time)
: this slider allows you to regulate the attack time of the filter envelope,
meaning the time the sound takes to reach the maximum cut-off frequency when the note has
been played.
•
[DECAY]
(Decay Time)
: this slider allows you to regulate the decay time, meaning the time from
when the filter reaches the maximum cut-off frequency to when it reaches the Sustain condition.
•
[SUSTAIN]
(Sustain Level)
: regulates the level of maintenance of the cut-off frequency value.
The duration of this segment is controlled by the Sustain Time parameter, displayed in the
EDIT FILTERS / ADV-ENV display page (see point 8.4).
•
[RELEASE]
(Release Time)
: regulates the release time, meaning the time from when the key is
released to when the filter no longer affects the sound.
See next the example of a typical ADSR (Attack, Decay,
Sustain, Release) envelope applied to the filter, which
therefore specifies how the character of the sound changes
over time:
•
[ENV DEPTH]
(Envelope Depth)
: you can use this filter to
regulate the depth of the envelope applied to the filter.
Turning the trimmer clockwise from the centre increases
the modification of the timbre; when it is turned anti-
clockwise from the central position the modification will
be increased in the opposite direction, while with the
trimmer in the central position the envelope will not affect
the filter cut-off frequency.
•
[LFO1 DEPTH]: regulates the depth of the modulation
by LFO1 of the timbre (with cyclic variation) of the signal
leaving the filter, generating wah-wah type effects, for
example. With the knob turned completely to the right
the filter will be affected by the maximum LFO1
modulation depth, with the knob central the filter will be
unaffected by the modulation, and with the control
turned completely to the left the maximum modulation
depth will be applied but with opposite phase to the
first condition.
