Well, only one CPU goes to 100 % at a time, but it changes from one to another.
Also, it only happens once processing is turned on.
I noticed some layout changes between the default 4.3.2 bidule I've been using
and the new 4.6.
In the 4.3.2, the outputs of the ZAG feed the ZMon, while in 4.6, it's the outputs of the Limiters
In 4.3.2, the Normalization sends 2 channels to ZAG, and 2 to ZMon, in 4.6 it sends to ZAG and Limiters
Also, I have a red circle/slash next to ZPlayer 1.4.
I assume this is all correct, because I never change anything here except to add my output device.
The odd thing is that it works perfectly with 4.3.2. I can switch back without closing Plogue and not have any issues.
It could just be my setup. I'm happy with 4.3.2, really!
