SX 2.2 CPU hit with Mackie Control...

Archived from groups: alt.steinberg.cubase,rec.audio.pro (More info?)

I've been using SX 2.2.0 on a dual-867MHz Mac, with Reason 2.5 as a
ReWire slave. Up to now I've never run into CPU issues...until I
connected a Behringer BCF2000 in Mackie emulation mode.

Now, suddenly, it seems like I can barely play back anything of any real
complexity, even if I freeze VST instruments. I can't believe that
sending MIDI control data from Cubase to (what it thinks is) a Mackie
Control should be that CPU intensive. Has anyone else experienced this?

When I set up the BCF2000 as a normal MIDI controller, this doesn't
happen, although I don't get flying faders or encoder readback.

Does Cubase SX 3.0 or Logic 7 deal with these any better?
