OSCAR delivers some default layouts to control RME’s digital mixer TotalMixFX. Of course you can also add your own custom layouts. To do this, just copy the layout file onto your device (e-mail, usb-connection, dropbox) and choose it via the „add layout“ dialog. The fastest solution is dropbox or similiar to automatically sync the layout files to your device. You can then update the layouts by one click.
Active layouts can be selected to quickly switch between them using a sidebar on the left side.
