There are no dumb questions, really, just impatient people. LOL
No Freezing turns midi data into an audio track. It's temporary not like bouncing it down to audio. See this
https://www.cakewalk.com/Documentation?product=SONAR%20X2&language=3&help=Mixing.23.html When you use Melodyne you have to create a Region Effects version of it, whether it's a clip or whole track. When you get done editing (and certainly before closing the project) in Melodyne, you have to Render the Region Effects "back" into "regular clip-ness" (LOL I like to amuse myself). So, freezing and rendering a Region Effect are not really similar at all.
When I started editing tracks in Melodyne (without watching any videos... duh), I would close the project leaving my Melodyne Regions "open" (ie not rendering them) and that caused problems. Now I've learned my lesson and render each clip before even moving on to the next one, or closing the project.
