About this build v0.2.22

What changed

Preset mode now hides detailed module controls, including Neutral, for a much cleaner default effects view.
Choosing Custom reveals the exact current settings without resetting or reapplying anything.
Track menus now show only presets appropriate to guitar, vocals, drums, bass, keys, backing, crowd, or unknown roles.
The master bus has its own full-mix presets instead of instrument choices.
New clean, warm, air, thickening, bus, keys, backing, crowd, and master presets expand useful choices without cluttering every track.

Known limitations

Changing a track's assigned role can make its current named preset inappropriate; Stem Hero then switches the label to Custom while preserving the complete sound. Presets remain starting points, not loudness-matched mastering decisions.

Keyboard

Space plays or pauses. Home stops and returns to the beginning. Shortcuts are ignored while a control or text field has focus.

License notice
