The electric piano patches are fascinating. They aren't trying to be a Rhodes. They are that specific "FM-style" tine sound that every R&B ballad from 1995 used. In Kontakt, these samples benefit massively from modern key-tracking. They sit right up front in the mix, cutting through drums with a percussive "clunk" that is surprisingly useful for neo-soul productions.

If you share a link to the specific X5D Kontakt library you’re considering, I can give you a more targeted pros/cons. Otherwise, treat most third-party X5D Kontakt libraries as ROMpler snapshots , not virtual instruments.
