I had an issue with one pluging being very heavy on the CPU,
It later dawned on me the plugins own effects were the cause,
especially convolution reverb. I turned them off (and plugins with animations ).
(I’m not fond of aturias augmented strings,
too bloated and pretty looking with lots of wasted screen space)
All of the PC’s outs straight to a mixer, turned of the effects on the plugins
and used an external effects proccesor via the mixer instead. The CPU load dropped
dramatically. It might seem like an obvious fix for some, I didn’t realise until
last night. I’m still relatively new to Cantabile and plugins, It was cool having
a fix so easy, the answer was there all the time.
