to which your MIDI device is assigned.
MIDI Trigger g roup
Defines the type of MIDI event (message) that will
drive the mot ion. There are four options.
Note: Whenyouchoosethisoption,thenote
number or pitch defines the output value. The
value is derived from where the note fal ls 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 b etween 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 me rely
specify which notes are valid to press. The v alue

The Sustain setting defines how long it takes the
valuetomovethroughtheparabola.Whenyou
choose Variable, the sustain length is also scaled
by how hard the key was pressed.
Pitch Bend—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 ev ent 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 specify slider.
Note Range group
Low Note /Hi gh N ote—Set these to specify the low
and high ends of the note range when the Note
option under MIDI Trigger is turned on.
Parameter Scaling group
Cont ains the Min and Max spinners, which specify
