Thanks GP. I used Roy Peters equipment to record. The microphones were a RODE pair. They were sitting on a tripod about 4 feet to the back and center of the piano.
Below is a very interesting set of recordings. The first is a recording of my piano LX playback using the Zenph
reproduction. I placed the same microphones under the piano on top of a moving pad (just lay the tripod over). The idea was to get rid of any room sound. Goldberg Variation 20 Zenph LX playback - Baldwin C Wapin
Next, I ripped the same track from the original 1955 recording of Glenn Gould. 1955 Glen Gould Goldberg Variation 20
Finally, I took one channel from the 1st recording and the other channel from the Glenn Gould recording so they play simultaneously together. It's truly amazing how accurate the Zenph Lx playback is compared with the original recording.
The best way to listen to this last file is to pan from left to right channels, back and forth to hear the difference. In case you get confused as to which is which, there is a small rest between the first have of the variation and the second half. If you're listening to the Glenn Gould you will be able to very clearly hear the reverb of recording studio. Mix - my piano and Glenn Gould
I'm not sure but I believe this is not a copyright infringement because it is fair use. I might be wrong.
