AWM ELEMENT DATA
2. AWM EG
JUMP #258
Summary: This determines how the volume of an
AWM element will change over time.
Procedure:
From: AWM Element job (JUMP #256)
directory
Select: job 02:EG. (JUMP #258)
Specify: volume EG parameters
EG Mode (Mode = hold, attack): This setting
determines whether the first segment of the
AWM EG will begin from level 0 (attack mode)
or from from maximum level (hold mode).
The AWM EG is graphically displayed.
This indicates the time range of the EG graphic
display; "x1" displays the shortest time with
the greatest detail. To change the time range,
press F1-F6 (x1, x2, x5, x10, x20, x50).
This indicates the segment from which the EG is
displayed. To begin the graphic display from a
different segment, press F7 or F8 to select
Seg1...Seg4orRel1.
Hold Time or Rate 1 (HT=63...0 or R1=0...63):
If the EG Mode is set to "hold" this will deter-
mine the Hold Time for which the level of the
waveform is held at maximum. A setting of
HT=63 results in the longest time. If the EG
Mode is set to "attack" this will determine Rate
1 of the EG. A R1 setting of 63 results in the
fastest attack.
Keyon Rate 2-4, Release Rate (R2-R4 = 0...63,
RR = 0...63): These settings determine the
speed of the operator EG. Higher values result
in faster change.
Rate Scaling (RS = -7...+7): Rate Scaling
allows the operator EG rates to be increased or
decreased depending on the key that is played.
For positive settings the EG rates will increase
as you play higher notes, resulting in shorter
envelopes. For negative settings the EG rates
will decrease as you play higher notes, resulting
in longer envelopes.
Keyon Levels 2-3 (L2-L3 = 0...63): These
determine the levels of the AWM EG. There is
no L1 setting since the AWM EG either begins
from 0 and moves toward maximum level (in
attack mode), or begins at maximum level and
stays there until the hold time has elapsed (hold
mode). Nor is there a L4 setting since the level
of the AWM EG immediately begins to move
toward 0 after reaching L3. If you want the
sound to continue sustaining as long as you
press a key, set R4 to 0. However some AWM
waveforms naturally decay to zero, so setting
R4 to 0 will not make these waveforms sustain.
In normal mode the AWM EG level will begin
from 0 and rise at the rate of R1 to maximum
level. When maximum level is reached it will
move at the rate of R2 to level L2. When level
L2 is reached it will move at the rate of R3 to
level L3. When level L3 is reached it will begin
moving at the rate of R4 to 0. (If rate R4 is 0, the
sound will move at an infinitely slow rate toward
zero; i.e., it will sustain at level L3 as long as
the key is pressed.)
When you release the key, the level will
move at the rate of RR to a level of 0.
Rates and Levels: The AWM EG will function in
two ways depending on the Mode setting.
