I use the arranger (a PSR-S910) for all my recording, using the PC just for burning the CD or converting the Wav to MP3.
I find having the styles and even the One Touch settings invaluable for getting down ideas quickly and painlessly.
I don't use any software recording programs, and prefer to do without them.
Congratulations on your PSR-3000...I had one, and it is a terrific instrument.
Ian
