Hi Dean,

Yes, you can get Mimic to work with any model, not just Poser. However, it's important to understand how Mimic works.

Mimic tells specific morph files how to change to match the audio. Those morph files all together make up what's called a DMC file (DAZ Morph Controls). They are shapes that the mouth makes during the pronunciation of vowels and consonants. 

So, if you have a model that doesn't have a prebuilt set of DMC files, you  need to create your own for use with the program. It takes awhile but is worth the effort if you are going to be doing some serious animation because manually adjusting morphs to match audio is a slow road to insanity. 

The documentation will cover how to do that.

DAZ does have a collection of free DMC files for many of their characters, including some of the free ones.
