I have 8 hardware devices controlling my Macbook - 5 of these have both MIDI and USB ports so I have the choice to either use MIDI or USB.

In my quest for offloading as much as possible off the CPU, I'm trying to have as many devices as possible just send midi into my setup (Unitor 8 midi patchbay into an RME FireFace) - like fader boxes and footcontrollers, latency is not too big an issue it's just for toggling FX and mixing, not for 'playing'

My thinking was that all these USB drivers could take up quite a bit of CPU time - it may be a hangover (still) from the early USB devices which had lots of problems and could hijack resources. My question: is this worthwhile to pursue or am I chasing the wrong thing?
