Users of the Cakewalk software programs will need an instrument definition file for their particular keyboard.
This page lists Instrument Definition Files for a number of Yamaha Tyros, PSR, CVP, DGX and YPG keyboards collected from various sources. Thanks.
Please notice that I do NOT check the files. Please contact the creator (normally shown in the file) for error handling.
Furthermore you will find links to sites explaining the use of the files; and how to create an ins-file yourself.
