I recently purchased my PSR2000 and really love it. I've used it on the job many times and as well as recording our nights off the Mackie. It's one great sounding keyboard! I, too, had a noise problem with the harmonizer. I finally fixed it by running my SM58 through the Mackie (instead of into the back of the 2000) and then sending a LINE feed back to the PSR. This greatly improves the signal-to-noise. Don't be afraid to see the green light is on most of the time....just be aware of the red light on the 2000 showing distortion. Also, be sure to use the internal noise gate. The harmonizer works great like this and the annoying hiss is gone for the most part. It will always be there slightly in the background. You'll notice this if you hold down a left-hand chord and sing without the styles, but it is so minimal no one will notice it during performance. I don't think I would want to use the harmonizer when making my CD's, though. I'm pretty sure the noise would show up in a recorded mix with soft passages. Yamaha even mentions this....the harmonizer is really for "live" use only, and not in the studio. Good luck!
