Hide MIDI input device: For dedicated control surfaces, there is no reason to have the input device
be available to the edit page. If your custom controller is purely a control surface device, and there are
no other MIDI devices sharing the input with the surface, then you can use this option to hide the input
from the available input list. If you controller is part of a controller keyboard, then you might still wish to
be able to record MIDI notes, and as such you would want to leave this option unchecked.
Channels: This option species how many tracks your device is capable of mixing at one time, and is
used to dene how many tracks will be highlighted if the colour selection option is enabled.
If you are not using your controller as a mixer device, i.e., you are using it only to control the transport
functions, or VST plug-ins, then you may want to set this value to zero.
Parameters: This option species how many plug-in parameters can be manipulated at one time on
your controller. If you have eight unused rotary controls on your device, for example, you could set this
value to eight.
Edit control mappings: This option displays a control mapping screen, where you can link the sliders,
buttons, and rotary controls on your device, to functions within Tracktion. The mapping screen is de-
scribed on the next page.
Import/Export settings: You can import and export custom controller congurations, either to share
with others, or to copies for safe keeping when doing backups.
Figure 7.4.5 shows the controller mappings window. The mapping editor is made up of two columns.
The left-hand column shows mapped MIDI controllers, and the right-hand column shows the function
currently mapped to the controller.
To create a new mapping, click in the controller column, in the box labelled “click here to choose con-
troller.” You will be prompted to move the controller you wish to map. Adjust the controller and Tracktion
will detect it. Once the controller is chosen, Tracktion will create a new entry in the list. Now you can
click the parameter box and choose a parameter from the pop-up menu.
