The parameters provided here determine how the amplitude envelope generator
responds to changes in keyboard velocity and range.

Vel (Velocity sensitivity)
Range: -7 ... +7
Controls: [CS2], [-1] [+1], Dial
Determines how the output level of the current voice changes in response to
velocity changes (e.g. keyboard dynamics).
Plus “+” settings produce higher output level in response to higher velocity
values — i.e. the harder a key is played, the louder the sound. The maximum
setting of “+7” produces the maximum level variation in response to velocity
changes. Minus “-” settings produce the opposite effect: lower level in response
to higher velocity. A setting of “+0” results in no level variation.
AtkRateVel (Attack rate velocity sensitivity)
Range: -7 +7
Controls: [CS4], [-1] [+1], Dial
Determines how key velocity (keyboard dynamics) affect the attack time of
the amplitude envelope generator.
Plus (“+”) settings produce an increase in attack time in proportion to key
velocity, while minus (“-”) settings produce a decrease in attack time in propor-
tion to key velocity. The greater the value the greater the change in envelope
length.
RateScaling
Range: -7 ... +7
Controls: [CS7], [-1] [+1], Dial
Allows the overall amplitude envelope generator decay rate for the selected
element to be varied across the entire pitch range.
Plus (“+”) settings produce a longer overall envelope time for the low notes
and a shorter envelope 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 oppo-
site effect — short low notes and long high notes. A setting of “+0” results in
no envelope length variation.
