Here’s an overview of each of the libraries and instruments you mentioned, most of which are from Native Instruments or related to KONTAKT-based libraries. These libraries are commonly used for creating realistic, session-style performances in music production.
All these libraries are designed to offer incredibly detailed and expressive instrument sounds with an emphasis on realism. They're particularly useful in modern music production, where it's important to have access to professional-sounding instruments without needing a real player in the studio. These libraries integrate seamlessly with Native Instruments' KONTAKT sampler platform, allowing for deep editing and manipulation of sounds, and also providing ease of use for producers.
