Depends on how it's used. For example, Ardour allows you to
set the number of cores used. The default is 'all but one',
and that makes perfect sense.

Ciao,

I think that simply limits the number of cores, no guarantee that they will all be
used. If it runs lots of threads, as I assume it does, then the chances are it will
use as many cores as are permitted.

Fons description is correct.

Ardour carefully and deliberately creates as many realtime priority threads for DSP as told to, based on the number of cores that should be used.
