About this build v0.2.24

What changed

Effects are now directly available on every loaded track and the master bus; the redundant mixer-level Effects mode button has been removed.
Named presets remain compact while Custom reveals the detailed controls using the most recently selected preset as its starting point.
The large-decode confirmation now uses a higher, device-aware risk threshold so ordinary Rock Band multistem songs are not flagged merely for exceeding the old conservative baseline.
Low-memory devices retain an earlier warning, while mobile-class and desktop-class browsers receive additional practical headroom.
Diagnostics report the calibrated decode threshold used during preflight.

Known limitations

Decoded-memory estimates are intentionally approximate and browser limits vary by device and operating system. Very long songs or unusually large stem counts can still exhaust memory below the warning threshold. 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
