Hi Woland,

I was requesting that you drag the tracks to File Explorer, and open them in Media Player before taking them into Reaper, so I'm not sure what you mean by "does not work".

Did that bass track that plays at half speed in Reaper play normally in Media Player, or does it play half-speed there too?

Please try this exact test and let us know what happens. It's important that we figure out if Band-in-a-Box is exporting incorrectly, or if Reaper is importing incorrectly, and this will tell us right away. I have a feeling that the latter is the case, but we should make sure before proceeding any further.

Thanks
