5-3: Amplitude & Filter Decay Rate Key Scaling
attack 1 level varies smoothly between the breakpoints.
Amplitude & Filter decay rate key scaling produces natural decay 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.
DcRate
The "DcRate" parameter is linked to the main Amplitude & Filter "Rate: De-
cay" parameter, and has the same effect. This value also determines the main decay rate
on which all key-scaled variations are based (indicated by a dotted line on the graph).
Breakpoint 1 & 2 Key
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
Set the amount of decay rate offset for each of the breakpoints defined by the
breakpoint key parameters, above. Negative values reduce the decay rate, and positive
values increase the decay rate at the corresponding breakpoint. No matter what offset
value is chosen, the actual decay rate will never exceed its minimum or maximum abso-
lute value. When different offset values are applied to adjacent breakpoints, the decay
