unchecked, the control item generates the target
data type as specified by the settings below this
check box.
Making the source assignment
The source assignment is made in the Control
Assignment dialog box when you first create the
slider, knob or button as described in “Creating a
slider, knob, or button” on page 690. The source
can be changed at any time in the Control
Assignment window (see “Opening the Control
Assignment window” on page 691).
What is a source for the slider or knob? It is a device
other than the mouse which you can use to control
the slider or knob. Normally, you change the value
of a slider or knob by dragging it with the mouse.
At times, however, it might be useful to move it
from an external controller, such as the modulation
wheel or data entry slider on your MIDI keyboard
controller. To do so, set the Source assignment to
match the incoming MIDI channel and data type
for the controller you wish to use.
The source assignment consists of two things: a
type of MIDI data and the MIDI channel or track
from which the data is being generated.
Notice that the slider or knob can be controlled by
notes, velocities, pitch bend, controllers, or even
mono pressure.
Source MIDI channel
Set the MIDI channel to match the transmit
channel of the controller, pitch bend wheel, or
whatever you are using.
Source track
Notice that the source can also be a track. Source
data in the track then controls the slider. This
allows you to create interesting effects. For
example, you can assign the source of a slider to be
the velocities of notes in track 3. You can then
assign the target to be controller number 7
(volume) and assign it to the synth playing back
the notes in track three. When you play the track,
the slider reads the velocities and sends out a
volume controllers to match the velocities, thus
enhancing the volume change effect from the
velocities.
Only follow source when selected
When this option is checked, the control item will
only respond to source data with it is selected. (See
“Selecting control items” on page 695.) When this
option is unchecked, the control item will follow
source data whenever it is received by Digital
Performer. This option is useful if you have several
control items with the same source that you would
like to be able to control one at a time, as needed.
Changing the source or target
To change the source or target assignment, open
the Control Assignment window for the control
item as explained in “Opening the Control
Assignment window” on page 691.
Adding increment/decrement buttons to a
slider or knob
To connect a scroll button to a slider:
1 (Optional) Select “Snap to Grid” from the
Console window mini-menu to check it.
Doing so causes the button to be lined up with the
slider or knob. Otherwise, you may need to
manually adjust the position of the button to line it
up with the slider. The button doesn’t have to be
lined up, however; it will control the slider no
matter where you place it.
2 Insert the slider or knob.
