Yes, the Ensemble and MC200 use the same Music Library Structure and Files

In fact, if the Music on your MC200 is appropriate for what you want in the Studio, then probably best to do as follows

1) BackUp the MC200 to another Network Hard Drive (or USB if necessary)

2) Restore the same Backup from above onto your Ensemble

This will save a lot of File Importing and Re-Ripping etc.
