CPU saving mode? Gone in X?

I'm a late adaptor to Logic X, having used every version of Logic since Logic 4. I've searched, but can't seem to find the answer.

Did Logic X do away with the CPU saving mode? (I believe that is what they called it in version 9). This was the feature that allowed multiple instances of an audio track, or software instrument, to have independent control over the mute and solo buttons.

Currently, multiple instances of the same audio track or same software instrument ALL mute when ONE is muted.
