When I'm playing using my S-950 I just hit the USB recorder button, fire up the recorder and save the .wav file to the USB thumb drive in the keyboard. Then, when I get home, I put the USB drive in my PC, convert the file to an MP3 and save it to boxnet. If I want to make a CD, then I download the files I want, change them to the correct format and burn the CD's on my PC. The PC also has a program that allows me to print directly to printable CDs. Does a real professional job.
Now, I do not sell the CDs, instead I give them away as promotional material. I've given away thousands of them over the years and they have been extremely effective.
All the best,
Gary
