When I first bought my Korg X-50 I was very disappointed to find out that there were no instrument definition files available to use within my Cakewalk Sonar recording software. I searched all over the Internet and could find nothing. Finally, a most excellent member of the Cakewalk Sonar Forum put an instrument definition file together and emailed it to me! Thanks so much!!!
So that you don’t have to go through the same heart-breaking experience that I did, I have included a link for downloading that very file below. Just copy and paste into Notepad or similar program and make sure you name it with a .ins extension and then tell Sonar to look for and install the file. Enjoy!
