I loaded one of the two pgmusic demo songs for that Slo Latin Pno style and ran the Tempo up from the original 85-BPM for quite a ways before noting anomalies. The anomalies noted were more of the "playing" variety than being of degraded audio quality, however. Like the cat was overplaying for the tempo, which is the case after some point.

Here is an audio example of what I heard at Tempo = 120-BPM, made using the BIAB Render function to Wav file and then converted to mp3 using Audacity and the LAME encoder at 128kbps:

Slo_Bossa_Pno714_120-BPM.mp3

Perhaps you have a bad RealTracks file, that might occur.

I would have posted a higher bitrate, but wanted something that could stream easily for most users. It doesn't really matter here, the file sounds great in the .wav format anyway.

Perhaps you could do the same exact thing at your end, set the demo song to 1 chorus, then set the Tempo to 120, hit Play and then go to the Audio menu and do a render, convert to mp3 or use the Render to mp3 inside BIAB, then post it so we can hear what you're hearing, it might help sort things out?
