About this build v0.2.38

What changed

Volume faders require a deliberate horizontal drag. Taps and vertical swipes do not change levels.
Basic Mode gets a polished mixer finish, clearer Pan labels, distinct Solo styling, and a subtle animated meter mark.
The mixer shows track count and the current quick mix or Custom mix.
Basic Mode remains the first priority. A matching, richer Nerd Mode redesign follows.

Known limitations

Streaming remains experimental, off by default, and not described as sample-accurate. Automated recovery can be audible. The stable engine still retains complete-song AudioBuffers.

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

This build contains original HTML, CSS, and JavaScript with no bundled third-party runtime libraries, codecs, fonts, artwork, or songs. No project-wide open-source license has been selected yet. Users are responsible for having the right to use files they load.
