If you open Studio One and scroll through "Instruments > Presence XT," you will see the standard folders: Pads, Keys, Bass, Drums, Synth Lead, Synth Pad, etc. But the top library secrets are in the "Inspired" folder.

Most stock libraries have terrible acoustic guitars and pianos. The Core Library is the exception.
