Hi everybody,

I have already posted this message in the Reaper-Forum. I'm experiencing some strange problems using Reaper and the RME Babyface with the latest firmware/driver.

After recording some 40 tracks for my Reaper project at a buffer size of 96 and 128 samples I wanted to give my PC some breathing room for the mixing stage by raising the buffer size. This is when it happens: the higher the buffer size I use, the *more* crackling I get. It starts at 256 samples and gets worse at 512 and 1024. When I chose 2048 samples, there is no sound at all. It doesn't matter if my project contains 40 tracks or only one track. The use of FX doesn't change anything, either. Always the same thing.

I'm not experiencing the same problem in Cubase 4 Essential. Therefore I guess it must be a Reaper problem. However, I'd like to see if anyone from the RME-side has any idea. My PC is an Intel Core2Quad Q8200 @ 2.33 GHz and 3,25 GB RAM, using Windows XP Service Pack 3.

Thanks for any help.
