Thanks I'll give that a go. I was actually thinking of a slightly more radical approach which, in testing avoids all the slowness completely. Basically casting each layers animdata into the Trax as a clip, then simply merging the clips and activating the results. The Trax merge is pretty much instant, no baking involved at all.
