5-1: Amplitude & Filter Attack Rate Key Scaling
portion of the envelope (“
Rate: Decay
” parameter) will not be produced.
Amplitude & Filter attack rate key scaling produces natural attack rate variations
across the range of the keyboard by allowing different rate offset values to be applied to
each of two breakpoints set at appropriate keys.
•
The § and ¶ buttons (“
Bpag
” and “
Fpag
”) can be used to go directly
backward or forward to the next Amplitude & Filter key scaling page without
having to return to the main parameter page.
● A1Rate, A2Rate
≤
0 … 127.
The “
A1Rate
” and “
A2Rate
” parameters are linked to the main Amplitude &
Filter “
Rate: Attack1
” and “
Rate: Attack2
” parameters, and have the same
effect. These values also determine the main attack rates on which all key-scaled varia-
tions are based (indicated by a dotted line on the graph).
● Breakpoint 1 & 2 Key
≤
C-2 … G8.
Allows two separate key scaling breakpoints to be set at any notes between C-2 and
G8. You can position the cursor at the appropriate breakpoint key parameter and use any
of the normal data entry procedures, or use the keyboard. To use the keyboard for break-
point entry, position the cursor at the appropriate breakpoint key parameter, press the •
button (“
Kbd
”), and then press the key at which you want to set the breakpoint while
“
Kbd
” appears in inverse characters.
No breakpoint can be set to a key lower than the breakpoint to its left.
● Breakpoint 1 & 2 Offset
≤
-64 … 63.
Set the amount of attack rate offset for each of the breakpoints defined by the
breakpoint key parameters, above. Negative values reduce the attack rate, and positive
values increase the attack rate at the corresponding breakpoint. No matter what offset
value is chosen, the actual attack rate will never exceed its minimum or maximum
absolute value. When different offset values are applied to adjacent breakpoints, the
