So I am working on a modular environment in Max to use live. I've settled on a nested poly~ formation so I can switch out DSP chains without the DAC having to be rebuilt and can have flexibility over muting modules etc.

While testing a few things I've noticed even with all voices muted the CPU meter was reading the same as if all voices were active. I've narrowed it down to the 'parallel' attribute. It seem when parallel is enabled muting voices has no effect over CPU load, however when 'parallel' is set to '0' poly~ works as expected.

Is this a bug or just something that has to be worked around? If it isn't a bug surely it renders the parallel flag useless for most tasks?

I have attached a project that shows the issue.

For the record I am running OSX 10.10.5 on a 2.5GHz i5, Mid 2012 Macbook Pro.

i do indeed have seen such strange, similar behaviours occasionnally... and i wonder too

Poly~ parallel flag and CPU. Bug?
