to which your MIDI device is assigned.
MIDI Trigger g roup
Defines the type of MIDI event (message) that will
drive the motion. There are four options.
Note: Whenyouchoosethisoption,thenote
number or pitch defines the output value. The
value is derived from where t he note falls within
theNoteRange,specifiedintheNoteRangegroup.
When the note is at the bottom of the range,
thevaluetakesontheMinvaluespecifiedunder
Parameter Scaling. When the note is at the top of
therange,thevaluetakesontheMaxvaluefrom
the same area. Anything in between is interpolated
betweentheMinandMaxvalues.(NotethatMin
doesn’t have to be less than Max.) The generated
value will slide around as different keys are
pressed. The harder a key is pressed, the faster the
value changes. The Speed setting defines how fast,
overall,thevaluechangesaskeysarepressed.
Velocity—When you choose this option, the
velocity of the note pressed determines the output
value. The notes set under Note Range merely
specify which notes are valid to press. The value

The Sustain setting defines how long it takes the

choose Variable, the sustain length is also scaled
by how hard the key was pressed.
Pitch B end—The MIDI instrument’s pitch bend
knob defines the value. The Note Range doesn’t
apply in this case and is disabled.
MIDI Controller—Specifies a note event when you’re
hooked up to a different type of MIDI controller
than the t ypical keyboard. For example, if you’ re
using a MIDI slider box, you would select the MIDI
Controller option, and then use the # spinner to
specify the note event for the specif y slider.

and high ends of the note range when the Note
option under MIDI Trigger is turned on.
