Applies live, and is remembered across reloads. Every Tiliqua also enumerates as an output, because macOS opens both directions together — nothing in the gateware plays host audio, so those entries are marked rather than hidden. No sound is a real sink, not a gain of zero: the meters go on reading.

Where 📂 LOAD reads and 💾 SAVE writes. The browser hands the page a file handle and not a path — the folder you picked is deliberately not readable by a web page, so the name is all this row can say. Clear puts this browser back to how it greets a first visitor — an empty USER bank, the demo songs as shipped, and no remembered target. It clears what the browser holds, never the file on disk.

On the board is the build stamp the module reports over USB — its own answer, not this page's. Only the Tiliqua can give one, and only a bitstream built after the stamp existed; the Basys 3's link is a raw UART with no descriptors of its own, so it has no way to say. This repo ships is what boards/*/firmware/ holds right now, read out of the artefacts themselves — the Vivado header in top.bit, and the tar entry of the Tiliqua archive's inner bitstream, which is when it was built rather than when it was copied in. The two clocks are minutes apart on purpose: the module names the instant its build started, the archive the instant it finished. The commit is the part to compare.
Ask the board is there because macOS does not pass that stamp through unchanged — it caches every USB name it has seen for a module, keyed on fields that are the same in every build, so after a reflash it keeps reporting the build you just replaced. The button reads the module directly instead. It opens the browser's device picker once per site and never again; nothing is sent to the module and no audio or MIDI is interrupted.

Keys — on-screen, or the computer keyboard: A S D F G H J K L ; ' are the white keys from C, W E T Y U O P the black ones between them. Z / X shift the octave, Esc panics.
