This works fine with most other plugins, but Pigments in particular makes the CPU meter jump around and spikes all the time with this setting enabled, causing crackles and pops. This gives Pigments its own process with a 1024k block-size, and I'm using 44.1kHz and some times 48kHz sampling with 24 bit-depth, 64bit processing on a modern MacBook Pro (Intel i7). S1 has this functionality that it gives plugins a separate process with separate block-size settings for instruments and audio while still managing to keep the latency low.

I also have some annoyingly high CPU usage numbers when using Pigments in Studio One 4.5 Professional.
