AMPLITUDE ENVELOPE GENERATOR (AEG) RATE SCALING

Summary: Allows the overall amplitude envelope
generator decay rate for the selected element to
be varied across the entire pitch range.
Settings: -7 ... +7
Procedure: Use the [DATA ENTRY] control, [-1/
NO] and [+1/YES] keys, or numeric and [ENTER]
keys to set the desired degree of rate scaling.
Details: Plus ("+") settings produce a longer overall
envelope time for the low notes and a shorter en-
Summary: Allows four separate amplitude enve-
lope generator level-scaling breakpoints to be
set at any notes between C-2 and G8 for the
selected element.
Settings: C-2 ... G8
Procedure: Use the
select the desired breakpoint (BP1, BP2, BP3
and BP4, from left to right), then use the [DATA
ENTRY] control or [+1/YES] and [-1/NO] keys to
set the breakpoint note.

AMPLITUDE ENVELOPE GENERATOR (AEG) LEVEL SCALE OFFSET

Summary: Sets the amount of level offset for each
of the four level-scaling breakpoints set in the

velope time for the high notes. This is useful for
simulating instruments such as piano, in which
the low notes take much longer to decay than the
high notes. The maximum "+7" setting produces
the greatest envelope length variation across the
pitch range. Minus ("-") settings produce the
opposite effect — short low notes and long high
notes. A setting of "+0" results in no envelope
length variation.
Refer to: "AMPLITUDE ENVELOPE GENERA-
TOR (AEG) MODE/LEVEL/RATE," page 64.
The breakpoint can also be set by pressing
the [ENTER] key — "KBD" will flash on the
display — and then the key on the keyboard cor-
responding to the desired breakpoint.
Details: Level scale offset values arc applied to
each of the breakpoints using the LEVEL
SCALE OFFSET function described below.
Natural level variations can thereby be produced
across the range of the controlling keyboard. No
breakpoint can be set to a key lower than the
breakpoint to its left.
