I am having a strange problem with Rhino: it crackles when there is a tempo change on the master track. Using Win 7 64, Reaper 64, Rhino 2.11. Any ideas what may be causing this? I tried 44 and 96 khz, and max buffer on my sound card. It happens on some patches but not others. For example it happens on the velocity rhodes - basic fm2 patch but not on the harpsichord patch found in the stock library.

Any ideas? I am trying to get a fraps video of the problem, but I am having difficulties getting the sound to record. I will upload and post a link to the video here if I ca get it to work.

Possibly due to one of the tempo-synced effects ? Try bypassing the built-in effects and see if the crackle still occurs...

Yep, in this case a 'cross ensemble' was the problem. Thanks!
