Thanks, I will try playing around with noise reduction. I got an acceptable but not optimal fix from cutting out the very bottom end, which cleans up the noise so the recording seems listenable to me, but it does take some of the punch out of the piano. A friend with stand-alone pro gear will try to notch out just the noise for me, and I'll learn more about Wavelab plugins, maybe we'll get something better in the end. (I have pc not mac setups).
