If you do not have the Instrument Definitions for your hardware, you can either import them or create them yourself. We have an in depth article on our website that discusses this available by clicking here.
 

Please Note: More in-depth information about creating/importing/assigning Instrument Definitions specific to your Cakewalk software can be found in your Help documentation. Press F1 to load your Help document and see the Topic and Sub-Topics under "Instrument Definitions" displayed on the Content tab.
