Hmm. I haven’t seen or read about that. My first thought would be to reboot.

You did some good troubleshooting. I wonder, perhaps check the box for “This song has problems” which would turn off the Fast Generation.

Which exact RealDrum, by number, is this? I’m not at a PC but want to check this later.

Are you using the new WAS driver? Are you on build 505?

A very remote possibility is that this specific song file is corrupted. In other words, reconstruct the song and it may be OK.

Keep us informed.
