The full-feature desktop console (big TFT, arcade buttons, instrument pass-through) is repositioned as the "Teacher" for studio desks and lessons: - stage.html -> teacher.html, info-stage.html -> info-teacher.html (git mv) - all links/paths, the embed variant (stage -> teacher), nav, cards, embed docs, README, build.sh + deploy.sh updated; deploy cleans the stale live stage files The "Stage" name is now free for a forthcoming foot-pedal stompbox (/stage.html).

<h2>Designed for</h2>
|
||
<p>The studio desk and the teaching room. Top‑mounted 1/4″ jacks keep cabling tidy; you plug your
|
||
instrument in, the metronome click is summed into the signal in the <b>analog domain</b> (no re‑digitising,
|
||
no added latency) and sent to a balanced 1/4″ TRS output for the desk or interface, plus a small monitor
|
||
speaker. Powered over USB‑C — a wall adapter, or a power bank. The colour TFT shows tempo, the item name,
|
||
and all lane patterns; arcade buttons + a recessed thumb‑roller make it quick to drive while you teach or track.</p>

||
|
||
<h2>Bill of materials</h2>
|
||
<p class="sub">Rough parts list — a desk/studio RP2040 build (USB‑C powered) with analog click injection.
|
||
Ballpark one‑off prices (USD); cheaper at volume.</p>
