Hello,

Using 2020 BIAB Windows on a Win11 laptop with no issues for years...... except:

I must increase the BIAB pitch by 3 semitones to match the instrument as played in the key chosen.

For instance, I practice a 2-5-1 progression in C major, but must write it into BIAB in the key of A major.

Interestingly, the keys match up in Realband and all other software and DAW's on the laptop.

in addition, BIAB 2020 is loaded on a W10 tower and an old W7pro tower with no issues!

Any help toward resolving the anomaly would be appreciated.

On a side not, I just purchased a Macbook M3 and will be adding BIAB 2025 Mac soon.
