processing.
MIDI control of parameters
GT Player Express allows you to control effect parameters and rack controls via an
external MIDI controller.
Effect parameter mapping is saved into the GT Player Express Program in such
a way that every Program can have different mapping. In contrast, rack control
mapping (e.g. Input level, Output level, Track Speed, etc.) is shared among all
programs.
Effect parameters can be assigned to MIDI controllers by using the ASSIGN button,
or via the MIDI Mapping window. Rack controls can be assigned to MIDI controllers
only in the Mapping window.
Press the MODE button to select Effect mode. Now you can see the parameters
of your effects on the GT Player Express display, (effect name, parameter name
and parameter value). Changing a parameter in GT Player’s Effect Editor display
always keeps a track on the selected parameter. You can simply assign the
currently displayed parameter to a MIDI controller. If a MIDI device is connected,
move the controller and press the ASSIGN button. This assigns the displayed effect
parameter to the last-touched controller.
You can use the MIDI mapping window to assign controllers to parameters.
< Press the OPTIONS button and select MIDI Mapping from the menu. Here
you can see, add, delete and change which controller is assigned to
which effect parameter.
You can also assign mapping for rack controls here.
< Mapping of some the Track Player and ReWire* Player parameters is more complex. Transport functions (Play/Pause/Stop), seek functions
(Fast forward/backward) are mapped to one continuous controller in a manner similar to the jog-dial wheel on some video recorders.
With such a controller, different actions are taken based on the controller value.
*ReWire: Audio streaming technology developed by Propellerhead Software AB.
In the MIDI pane of GT Player Express’ Preferences menu you can also:
< Select the MIDI channels on which you want to control effect parameters and rack controls.
< Allow the external selection and loading of GT Player Express programs when MIDI Program Changes are received.
Windows:
< To automatically assign an incoming controller to a selected parameter, activate learn mode by clicking the LEARN button or pressing the
Insert key.
< To clear mapping for selected parameter, press the Delete key.
Macintosh:
< Click the ASSIGN button to assign last received controller to selected parameter.
