Today I tried the new V2 bass tuning calculation. On the Hoffmann T186 and Hoffmann P206 the tuning was fantastic. I couldn't even believe what I was hearing.
I had a little reservation on the T161 - it was a little sharper than I would have expected, but nothing I had a problem with. Compared to the V1, it was great.
Next, I tuned a Raehs piano (about 131) that still had steel strings in the bass. The piano is 130 years old. Serial number 953. The two chords were fine, but the single chords were very sharp. I was putting them very down on the ear. I sent you the recording from Pianoscope. It's true that this piano had extremely ugly inharmonics. And I recorded the bass about five times. I guess you can't take this as a reference piano for adjusting the tuning curve in V2, but rather I sent it to you as a point of interest. The A0 tone after tuning by ear Pianoscope wasn't even able to register in the recording as it must have been low.
