The Library
The Library is where you find sounds and building blocks and drag them into your session: sets, layers, instruments, generators, controllers, effects, and samples. It has three sections: Play, Build, and Folders.

From the library, you can:
- drag & drop sets onto the set manager
- drill down into a session by double-clicking it to see the individual sets it contains
- drag & drop instruments, generators, controllers, samples, and effects into your working set
- open a session by selecting it and choosing Load session
- keep the things you use most in Favorites
| Shortcut | What it does |
|---|---|
| ⌘ + ⌥ + L | Show or hide the library |
| ⌘ + F | Search the library. Start a search with # to search by tag. |
| ⌘ + ⌥ + F | Search the set tree (Edit view) |
Play
Play holds ready-to-play sets and sessions, in these tabs:
| Tab | What's in it |
|---|---|
| Favorites | Everything you've marked as a favorite, from anywhere in the library. See Favorites. |
| Core Sounds | The Core Library sessions that come with Sensory Percussion. |
| Sound Packs | Sound packs you've installed with File → Install Soundpack…. |
| User Packs | Sound packs of your own. |
| Sessions | Your saved sessions. The Workspace is pinned at the top. |

Favorites
Favorites is the first tab in Play. It collects the sets, presets, sessions, samples, and folders you've marked, wherever they live in the library, so the things you reach for most are one click away.
To mark a favorite, click the heart at the right edge of its row, or right-click it and choose Add to Favorites. Select several items first to mark them all at once. On a favorite, the same menu item reads Remove from Favorites.

You can favorite:
- Sets inside a session, from the Core Library, a sound pack, or one of your own sessions. Sets of the session you have open aren't offered, since they're already in front of you.
- Presets: instruments, effect presets, and module presets, whether factory, from a sound pack, or your own.
- Sessions: a whole
.sp2from Core Sounds, Sessions, or a bookmarked folder. The pinned Workspace can't be a favorite. - Samples from Samples, a sound pack, or a bookmarked folder.
- Folders: any folder inside a tab. The tabs themselves can't be favorites.
The Favorites tab groups them under Sets, Sessions, Instruments, Effects, Modules, Samples, and Folders. A group only shows up once it has something in it, and each row is labeled with the library it came from.

Each favorite works exactly like the original. Drag a favorite instrument into your set, select a favorite set and click Insert Set, click a favorite sample to audition it, or open a favorite folder to browse it.
Favorites belong to you, not to the session. They're saved with your settings, so they follow you from session to session and survive sound pack updates. If a favorite's content goes missing (for example, you uninstall a sound pack), it drops out of the list until the content is back.
Core Sounds
The Core Library contains the six packs included when you install Sensory Percussion for the first time:
Acoustic Drums

This is a pack that includes sets with very detailed acoustic drum and percussion kits. Snares, toms, hi-hat, congas, dhol, udu, cymbals. Each drum often has a hundred or more samples mapped to it.
Chord Sequences

This pack includes sets with velocity-thresholded chord kits, which means that you have to intentionally hit one or more of the drums at a high velocity to trigger a chord sequence. The chord sequence by default is usually controlled by Tom 2 and/or Tom 1.
These sets also include percussive elements (and sometimes melodic elements), but their defining feature is the chord sequence.
Electric Drum Kits

What if E Drums were as responsive as acoustic drums? These Sensory Percussion sets consist of E Drum sounds that are as responsive to your playing as acoustic drums, thanks to a network of timbre and velocity assignments.
Electro Melodic

These sets contain at least one melodic element. Sometimes they are entirely melodic, but many also contain percussive elements. The melodic elements are often controlled by Tom 1 and/or Tom 2.
Patterns

Sequences inside sequences inside sequences. These sets showcase the power sequencer module, and Tom 1 and/or Tom 2 has a sequence that is unlocked by repeatedly striking the zone/s with the embedded pattern.
Worldly Sounds

This pack contains sets primarily made of sounds found on planet earth: dirt, sand, ice, you name it. Like the Electric Drum Kits core library pack, these sets are often as responsive to your playing as acoustic drums.
Build
Build holds the building blocks for creating sets: Generators, Controllers, Effects, Samples, and Instruments. Expanding a generator, controller, or effect reveals its presets, which can be dragged into your set just like the object itself.
Generators make sound or send a message: samplers, audio inserts, MIDI generators, and more. Apart from effects, most generators can't contain other modules.
Controllers help you organize, map, and route modules. They don't make sound themselves, but they contain generators and can even contain other controllers.
Effects can be dragged and dropped onto generators and controllers. When you drop an effect onto a module, that module's FX panel opens with the effect visible, so you can adjust it right away or add assignments by right-clicking.
Samples are audio files that can be dragged and dropped to create samplers, which can in turn be dragged and dropped into controllers. You can click on samples in the library to audition them.
Instruments
The Instruments tab holds every instrument you can drag into your set, in one folder per role: drumset, snare, kick, rack tom, floor tom, hi-hat, crash, ride, hand drum, and MIDI kit. When a role has instruments from more than one library, its folder splits by library: your own User instruments first, then Core Library, then one folder for each sound pack.

Folders
You can bookmark any folder on your computer in order to drag and drop layers from previously saved sets, as well as drag and drop audio samples and preset files that you have saved inside that folder. Click + next to Folders to add a bookmark.
