Setting up control surfaces
External devices
To disconnect a controller/surface from SONAR
1. Go to Edit > Preferences > MIDI - Control Surfaces.
2. In the Controller/Surface column, click the name of the controller/surface that you want to
disconnect.
3. Click the Delete button , which deletes the name of the controller/surface that you selected.
4. Click Close.
Control surface refresh rate
Control surfaces are refreshed by posting a windows message every 75 milliseconds.
CtrlSurfaceRefreshMS=<50 - 5000> (default=75)
You may wish to increase the value of this Cakewalk.ini variable if you are experiencing sluggish
UI responsiveness when using a control surface and playing back high CPU projects.
Also, if you are using a control surface that is not bi-directional, the surface does not need to be
refreshed at all and you can safely increase the value.
This variable should be set in the [Wincake] section. For example:
[Wincake]
CtrlSurfaceRefreshMS=75
