Yamaha CP33 instrument definition

  I'm trying to make a cakewalk instrument definition so midi tracks will list my Yamaha CP33 patches. I'm having a hard time with it. Has anyone made an instrument definition for this keyboard? Or maybe for a cp300, cp50, or cp1 that I can adapt to my cp33? I've read the Cakewalk help docs on instrument definitions and any articles I can scrounge on the internet. My midi tracks are still listing the standard general midi list of patches. I'm wasting a lot of time with this. Thanks in advance for any help. --- Jim
