The Controllers
The Controllers
Once you pass zero, you enter a range of “negative” Depth values that produce
reverse controller operation: i.e. the output level
decreases as you increase touch pressure.
Like the normal positive range, the negative Depth range is from “0” to “-127”.
NOTES ■ Many parameters with any relationship to MIDI control have a range of
values from -127 through 0 to 127 (255 steps). This corresponds to the range of
values that can be represented in binary form by one “byte” (8 bits) of data —
the number MIDI uses to convey control values.
8. Vary the Curve Parameter
You may have noticed in the previous step that the relationship between touch
pressure and output is not linear (the line in the graph is slightly curved). That is, a
change in touch pressure does not necessarily produce a corresponding change in sound.
The “Curve” parameter makes it possible to change that relationship.
As you increase the curve value (the maximum value is 16), the line on the graph
which represents touch pressure versus output will curve downward, as shown in the
display below (setting “12”). The result is that the lower end of the touch pressure range
has relatively little effect on the sound, while higher touch pressures produce more
dramatic changes.
Negative curve values (0 … -16) have the opposite effect: Output increases rapidly
at low touch pressures while higher pressures produce relatively little effect.
