Sometimes there’s a channel playing and after a couple of seconds, its sound just drops out. I think it’s related to the sound’s frequency like eg there’s a filter sweep going on and the freqs get too high (or low) and Renoise can’t cope with this anymore (just before the drop-out the sound gets more and more distorted). Sometimes even hitting the Panic button doesn’t bring the track back anymore, only a reloading of the xrns.
Btw, is there a crash/bug report file being created everytime Renoise crashes due to a bug?

This is under XP Pro SP2.
