3 - ADSR SETTINGS
This function sets the attack, decay, sustain, and release characteristics of the filter
ADSR envelope generator.
Application:
Change the filter cutoff frequency dynamically with respect to time.
1. With the module active, Current Voice assigned (see GENERAL INSTRUCTIONS 2),
and the ENTER LED either lit steadily or off, key in 3.
The display says:
Atk Dec Sus Rel
XX XX XX XX
...where X is a numeral.
Hint:
Filter and VCA settings interact. For example, if the VCA is set for an extremely
short decay, then you won’t hear the effects of setting a long filter attack or decay.
Atk,
controlled by Slider A, varies the filter envelope attack time from 01 to 32 (higher
values increase the attack time).
Dec,
controlled by Slider B, varies the filter envelope initial decay time from 01 to 32
(higher values increase the initial decay time). 32 gives “infinite decay” (envelope stays
at maximum amplitude for as long as you hold down keys).
Sus,
controlled by Slider C, varies the filter envelope sustain level from 01 to 32 (higher
values give higher sustain levels).
Rel,
controlled by Slider D, varies the filter envelope release time from 01 to 32 (higher
values increase the release time). A setting of 32 inhibits the release phase of the
envelope, thus keeping the filter open at the previously selected Sustain level. This is
useful if you want to trigger a long sound by simply tapping a key.
Note:
If the VCA and filter release are both at 32 (also see VCA/LFO 1), a key will
sustain at the sustain level even after you take your fingers off the keys. This is like the
HOLD function found on standard synthesizers. The sound will continue to sustain
unless you play more notes than there are available channels, in which case previously
assigned channels will be assigned to newly played notes.
