A MIDI track is usually assigned to a Synth track so they're tied to the same FREEZE button.
You can also have the synth track in the Track List if that's a better place for the Freeze button.

Not really I have hardware synths and use them still. A freeze would do nothing except confuse the heck out of me.
I guess what I was trying to get at is freeze is used to effect audio not MIDI. When you freeze a synth the MIDI is muted but otherwise not effected.
