What's New
Every update, in one place
Massive indexing & search speed-up
A ground-up performance pass for huge libraries: indexing is over 15x faster, search runs on a real full-text index, and duplicate samples no longer vanish from your packs.
- Indexing overhaul — a 290GB library with 164,000 files now indexes in about 2 minutes instead of 30+.
- Instant search — queries hit a full-text index instead of scanning every entry, so results stay snappy even in six-figure libraries.
- Duplicate samples fixed — byte-identical files in different packs each keep their own entry instead of silently replacing each other.
- Killed the hidden re-index loop that made Stack re-process thousands of duplicated files on every launch.
- Browsing and deep scrolling are dramatically faster thanks to a new sort index.
- Lower memory use while indexing — huge DAW project files no longer spike RAM.
- Ableton .als project info is now read correctly.
Favorites folders & drag-to-organize
Organize your favorites into colorful folders and file samples away with a single drag.
- New Favorites folders — create, rename, and color them right from the Favorites page.
- Drag any sample, MIDI, or preset onto a folder (from Browser, MIDI, Presets, or Favorites) to file it away — it's favorited automatically.
- Drag multiple selected samples into a folder at once.
- Favorites is now expandable in the sidebar, with a live file count on every folder.
- Give each folder its own color — pick from the palette or choose any custom color.
- Fixed scrolling on the Favorites, MIDI, and Presets pages.
Custom themes & window controls
