I did an experiment with this new great BiB 2024 v.1109.
1. Made a short 8 bar chord sequence, just 8 bars, no repeats.
2. Style ZZJAZZ, tempo 140.
3. For bass I chose Hi-Q Upright Acoustic Bass 'N'.
No Midi patch.
4. When I came back to Mixer I noticed that BiB had changed the Track name 'Bass* to 'Piano 1'.
And Piano track was changed to 'Piano 2' (of course).
5. I played my 8 bars and saved the result.
6. Exported the Song as Audio File. 24bit/44.1. Sounded OK.
7. Next I exported the Song as Audio File 24bit/48Khz. Didn't sound ok anymore. The tempo was faster and the pitch higher.
8. 24bit/96 was still faster like playing the 24/48 at double speed, high pitched. Funny but not in the right way, I think.

Could someone please explain why this happened?

And yes, the program seems to crash easily and too often.

I have had none of such difficulties with BiB 2023 v.1013.

My setup is I think quite normal: Windows 10 64bit Home with latest updates. Lenovo Legion Y730-17ich. Intel i5-8300H, 2.30GHz, 16 GB memory. RME Babyface interface/ASIO. N.I., IK and Steiberg, Finale and Reaper. I have used (on/off) BiB from the year 1, I think, from Atari and Windows 3 era, or so.

BiB v.1013 has been stable no problems so I continue using it.
