Hi Eddy,
Yes, David is fine.
On Op 23, you're referring to the Rachmaninoff Preludes, yes? I've also recorded 4, 5 and 6, some of my favorites. The other pieces sound interesting too. Looking forward to hearing your recordings!
Pro Tools 9 is very technical and complicated stuff for the novice from the little I've read of it. My own challenge would be understanding it after it was all explained to me

! One thing I would do though if I were you would be to make sure that the technician fully grasps the fact that you're a classical pianist. It would not be unusual to find that he works in the realm of jazz and pops, which is a world removed from classical and the many implications for making recordings. For example, for solo piano you really only need the purity of two tracks for two matched stereo mics, rather than 148 tracks or whatever. Anyway, I hope you have good luck with that!
David
