333Motion User Guide
Controller: Use this mode when the control is a knob, dial, key, slider, or foot pedal
on the MIDI device.
Learning: Use this mode to “teach” Motion which control (such as a knob, dial, or
key) you want to use on the MIDI device to manipulate the parameter to which the
MIDI behavior is applied. When in Learning mode, the first knob, dial, or key that you
adjust on the MIDI device is set as the control.
Note: When the MIDI behavior is first applied, Learning is the default control type.
ID: A slider that displays the identification number of the MIDI control (such as a knob,
dial, or key) that you are manipulating.
Value: A slider that displays the standard MIDI value between 0 and 1 when you’re
manipulating the MIDI control.
Scale: A slider that multiplies the Value parameter in the MIDI behavior. This means
that when Scale is increased, the MIDI control has a larger range of value and a greater
effect on the parameter it’s controlling. For example, when you use a knob to adjust
an objects rotation, the default rotation value range (when Scale is set to 1) for a full
turn of the knob might only be 30 percent. When the Scale value is increased to 13, the
rotation value of a full turn of the knob is increased to 370 degrees.
Apply To: A pop-up menu (parameter assignment control) that shows the parameter
affected, and that can be used to reassign the behavior to another parameter.
Add a MIDI behavior in Motion
You apply the MIDI behavior in the same way as all other Parameter behaviors. In the
following examples, the MIDI behavior is used to adjust an object’s opacity and rotation.
Note: This behavior can only be used if you have a MIDI device correctly connected to
your computer.
Use the MIDI behavior to adjust an object’s opacity
1. Select an object in the Layers list in Motion, then locate the Opacity parameter in the
Properties Inspector.
2. Control-click the parameter, then choose Add Parameter Behavior > MIDI from the
shortcut menu.
The MIDI parameters are displayed in the Behaviors Inspector. By default, Control Type
is set to Learning.
Like all other Parameter behaviors, the Apply To field displays the parameter to which
the behavior is applied.
