Buzz doesn't make use of all the processors it could

Post by DJ Saint-Hubert »

well maybe... all my instruments are routed into a limiter when they all merge together, but before that they branch out into their own effects chains. Couldn't there be a way to have them use a separate CPU for each chain and then wait a certain amount of time for the other chains to finish, and then process the "master" track where the limiter is? I know Reaper has multiple tracks running on their own processors and then does a Master effects chain on everything. Why not Buzz?

yeah, of course I've got that set to True. And all my processors are checked off in the other menu. Maybe it's not set to the right priority/mask?

This feature is highly dependent upon the topology of your signal path. If all your signal paths are highly interconnected, it won't multithread. Turn on the option to visualize which threads are being used. It color codes each machine by thread. Then do some experiments to see how your setup can best take advantage of multithreading. In general the principle is that each independent branch can be threaded, but you'll have to experiment to find out. It's one of the intricacies of building a good buzz setup. My setup fully takes advantage of all 8 cores.

oh, doh, I had Multithreading disabled under settings. It might work now. According to the color coding of the threads, it's using different processors for the different synth instances

I've always assumed this is of most value applied to heavy synths and effects thereon and subsequently compromised for sample-based sections of the setup to not multi-thread much or at all. In fact, I've got more into samplegrid recently which by virtue of its multi IO stuff doesn't seem to offer it at all, understandably I think. Perhaps my reasoning is flawed but certainly having several synths all split across multiple cores seems to make a big diff compared to say multiple trackers going through fairly rudimentary effects paths.

Diabling multithreading was in the past a measure against crackles and sound problems (as deaktivating HT in BIOS). So it can make sense to disable it. We will see how it is in the new ReBuzz :!:
