PARAMETER GLOSSARY
Note:
System Mode parameters are described in Section 3.
Dynamics parameters are described on pages 4-32
to 4-35. These parameters are not included in this
glossary.
"Adjust" (0 to 127)
Functions differently from preset to preset. "Adjust" is a
"magic" control that can manipulate several parameters
at once or provide a set of special values for a single
control. For example, it may be called (Fast) or (Slow) for
a parameter that is also settable to any value via another
control. "Adjust" has a range of 0 to 127 to provide a
convenient attachment point for a MIDI controller.
Attack (0 to 100 or 0 to 255)
Controls the sharpness of the initial response to an input
signal. High settings cause explosive sounds, while low
settings cause sounds to build up more slowly with time.
Attack only affects the level of sound within the first
50ms or so.
Balance (-100 to +100%)
In Rotary programs, determines the volume balance
between the horn and drum.
BassMult (0.2 to 4.0x)
Controls the reverb time for low-frequency signals.
BassMult works as a multiplier of the Decay and MidRT
parameters. For example, if BassMult is set to 2.0x, and
Decay is set to 2 seconds, the low-frequency reverb time
will be 4 seconds. For a natural-sounding hall ambience,
BassMult should be set between 1.0x and 2.0x.
BassXvr (28Hz to 19.4kHz, off)
Sets the frequency below which BassMult applies.
CmpAttk (4 to 125msec)
Controls the speed at which the compressor responds
when input signals increase above threshold.
CmpRatio (1:1 (off) to 10:1)
Sets the ratio of gain reduction for input signals above
threshold.
