# Your preset library

URL: https://presetti.app/guide/library

> Find the synths on your computer, pick the ones you want and build a library Presetti can search by sound.

## In this section

- [Find your synths](https://presetti.app/guide/library/scan-plugins): Analyse your computer so Presetti lists every synth it can use and counts each one's presets. It takes a minute and doesn't render any audio.
- [Build your library](https://presetti.app/guide/library/build-library): Pick the synths you want to search, then let Presetti render a short clip of each preset. You can pause, stop early, and add more synths later.
- [Check which presets are searchable](https://presetti.app/guide/library/view-presets): Open a synth's preset list to see which presets are searchable, which were skipped and why, and where each preset file lives.
- [Add preset folders and plugin folders](https://presetti.app/guide/library/add-preset-folders): Point Presetti at preset banks it didn't find on its own, or at plugin folders outside the usual places.
