No one can answer your question without knowing what sample rate you were running, or what the routing of your session is. The console itself shouldn't matter, assuming you are talking about using an analog or digital outboard console that you use for preamps, AD conversion, and DA and monitoring outside of Protools.

Protools Ultimate has 256 voices at 48kHz, 128 at 96k and 64 at 192kHz.

Protools Ultimate is about to get a major voice count upgrade which will give it 50% more voices at each respective sample rate. Unfortunately, the HDX cards won't be getting that upgrade, maybe ever, because there is a hardware compatibility that causes Protools to crash with the new firmware.
