- Remove the VCSL sample kit entirely (editor 351K → 141K). All voices are synthesized; the friendly GM names now alias to the punchier 808/909 renders (KIT_ALIAS). build.sh drops the @BUILD:samples inlining; assets/samples.json gone. - Conventions (backward-compatible): GM note-number aliases (36=kick…), '-'/'_' rest aliases in step patterns, Euclidean (k,n[,rot]) shorthand. - Per-lane gain in dB (@<db> in the grammar) applied as a velocity multiplier at schedule time — no stutter; threaded through every host's buildMeters + the editor's lanes (knob UI comes in Phase B). - 15/15 engine round-trip tests pass; pages console-clean.

Hardware-device MOCKUP / simulator for the Pi Pico (RP2040) build of the
|
||
Stackable Metronome. The physical unit can't show the multi-lane editor or
|
||
manage set lists — it just *plays* a configuration expressed in the share
|
||
language. So this page is the device front panel: load a patch or set-list
|
||
(paste one, open a #p=/#sl= link, or pick a saved one) and it plays it,
|
||
driving the OLED + beat LEDs exactly as the firmware would.
|
||
|
||
Audio here is the synthesized voice set (the firmware uses the same scheduler;
|
||
on hardware the voices map to CC0 samples on the I2S DAC). One file, no deps.

<h2>PM‑1 — Initial</h2>

<div class="ff-tags"><span>Concept</span><span>Idealized device</span><span>Not buildable as drawn</span></div>
|
||
<p>The idealized PM‑1: the player as a clean, screen‑first device with no concession to mechanical parts yet.
|
||
It's the look we design <i>toward</i> — full set‑list navigation, a colour beat display showing every lane,
|
||
light/dark theming, and a fullscreen landscape "stage" view. It runs the same engine and program strings as
|
||
everything else in the family, but as an <i>idealized</i> object, before deciding which buttons, encoders,
|
||
jacks and enclosure actually make it real.</p>
|
||
<p>Because it's a concept, there's <b>no bill of materials</b> — there's nothing to source for a render. The
|
||
buildable realization of this idea is the <a href="/teacher.html">PM‑1 Teacher</a> (full priced BOM there);
|
||
for the smallest practical unit, see the <a href="/micro.html">PM‑µ Micro</a>.</p>
