audio performance / blue full?

hello, if my audio performance bar is full in the blue line/ disk, it means I need more ram? or a faster hdd? or better icore?

Better cpu, better interface/audio driver or more sensible project management.

ok

better interface/audio driver

Motu 828 mkII is not good enough?

more sensible project management.

I was trying to work with some stems for mixdown… that was the problem… to many recorded in 32bit

Really?
32 bit files shouldn’t really tax the cpu significantly more than 24 or 16 bit…Sure it wan’t your disk meter?
By sensible project management I’m referring more to avoiding long chains of heavy plugs on single channels, buses or the master that may tend to overload a single core.
