If the device isn't seen as a MIDI input (USB endpoint pressure from drive+serial+HID+MIDI),
boot.py disables the unused HID interface and enables usb_midi — copy it on and power-cycle.
Bundled into pm_k1_circuitpy.zip; documented in the README.

Add to the editor's set-list ⋯ menu:
- 📟 Save to device — writes the active set list as programs.json (the same file the
PM_K-1 firmware reads). Uses the File System Access API to write straight onto the
CIRCUITPY drive (Chrome/Edge); falls back to a download to drag on. Reuses
setupToPatch() per item -> {title, programs:[{name, prog}]}.
- 📥 Load from device — reads a programs.json back into a new set list (patchToSetup
per item; reuses the existing import path).
Bundle the built editor.html into pm_k1_circuitpy.zip so the drive carries its own
offline programmer. info-kit + pico-cp/README document the workflow.
Verified: editor loads with no console errors; both menu buttons + all four functions
present; zip contains editor.html. (FSA save needs a real user gesture to test on-device.)

From on-board feedback (works well; minor tweaks):
- Pad grid uses circles now: big circle on each beat (division), small on the
subdivisions (vectorio.Circle — native, no extra cost), coloured/lit as before.
- Lane labels use a new small font (font_s.bin, ~12px via gen_font.py) so they're
half-size and show more of the voice name (e.g. 'hatClos').
- LED was blinding -> LED_BRIGHTNESS scale (default 0.15) applied on every write.
- Residual tearing -> SPI back to 62.5 MHz (vendor speed; smaller tear window on a
panel with no tearing-effect pin). Both are CONFIG flags.
Verified by rendering the full scene headless. font_s.bin added to gen_font.py + bundle.

On hardware the app rendered, beeped and took input, then died with MemoryError at
the text Bitmap alloc — the two ~37KB base64 font strings stayed pinned in RAM. Move
the fonts to small binary files read at boot (font_m.bin / font_l.bin), drop the
base64 + binascii, and gc.collect() before each text bitmap. code.py 56KB -> 20KB and
RAM use drops ~37KB+. Also: cyan rendered as yellow (R/B swapped) -> MADCTL 0x40 -> 0x48.
Bundle + README updated to include the font blobs. (LED still needs the neopixel lib.)

New pico-cp/ — a CircuitPython port of the PM_K-1 firmware so the Pico mounts as a
CIRCUITPY drive carrying its code + tracks (the MicroPython pico/main.py stays the
simple fallback):
- pico-cp/code.py: displayio BusDisplay driving ST7796 via a custom init_sequence;
smooth anti-aliased text via displayio Bitmap+Palette (reuses the baked font blobs);
vectorio rects for dots/buttons; DIY GT911 touch (16-bit regs, edge-detected);
pwmio buzzer, analogio joystick, digitalio buttons, optional neopixel RGB; the
polymeter engine on a time.monotonic_ns scheduler. Reads /programs.json (falls back
to baked defaults); CircuitPython auto-reloads on file change.
- pico-cp/programs.json: the 23 default grooves. pico-cp/README.md: flash + calibrate.
- build.sh/deploy.sh: bundle + serve /pm_k1_circuitpy.zip. info-kit.html: experimental
'CircuitPython edition — USB drive' section.
Verified in CPython (stubbed displayio): init sequence well-formed, parser handles the
grooves incl. (3,8) euclid + @-4 gain, and code.py's actual make_text renders identical
smooth AA text. Hardware bits (panel/touch/MIDI) await on-board testing.

A new, first-actually-buildable form factor for the 52Pi EP-0172 "Pico Breadboard
Kit Plus" (Raspberry Pi Pico; 3.5" ST7796 320x480 cap-touch via GT911, PSP
joystick on ADC0/1, WS2812 RGB on GP12, buzzer GP13, buttons GP14/15):
- pico/main.py — one self-contained MicroPython file: ST7796 direct-draw driver,
GT911 touch (16-bit register addressing), WS2812 RGB (neopixel), PWM buzzer,
ADC joystick, buttons. It parses the project's own program-string language
(verified against the web engine's semantics) and runs a non-blocking
ticks_us scheduler with an on-screen touch UI. CONFIG flags cover panel /
colour / touch / joystick calibration. pico/README.md has flashing +
calibration steps.
- kit.html — lean widget that mirrors the firmware's on-screen UI (portrait
320x480 canvas) plus a joystick / RGB / buzzer / A-B buttons; plays via the
shared engine. info-kit.html — the real EP-0172 pinout, a parts list
(~$45 incl. Pico) and the firmware to flash (downloads /pico-main.py, links
the README + source).
- Landing + embed page list the Kit; build.sh/deploy.sh build the two pages and
serve pico/main.py as /pico-main.py for download.

Previously every device .html bundled its full narrative (purpose, BOM,
dimensioned drawings, embedding docs) inside a #techinfo block that embed
mode (?embed=1) only CSS-hid — so every embedder and every landing-page
iframe downloaded all of it (showcase 77%, teacher 49% of the file) for
content no embedder ever sees.
Now:
- <device>.html is the lean widget only: header + front view/controls +
title + summary + program box. ?embed=1 still collapses to the bare
widget; the heavy narrative is gone from the payload.
- info-<device>.html (new, one per form factor) carries all the words —
purpose, dimensions, priced BOM, embedding docs — and embeds the live
widget at the top via the existing iframe + auto-resize protocol
(new shared src/infoembed.html + src/infoembed.js).
- Each device links out to its info page ("…dimensions & BOM →"); the
landing panes and viewport bar now offer both Open ↗ and Specs & info ⓘ.
- Dropped the now-dead "Show info" toggle (CSS + progbox.js).
Branding: adopt the official VARASYS "tagline on the bottom" logos from the
brand kit (light-background variant now matches; dark already did). The
tagline is baked into the PNGs, so remove the CSS .brand-tag / .dev-tag
spans and the showcase canvas-drawn tagline. Brand cyan #0AB3F7 / navy
#1C283F already match the official palette.
build.sh / deploy.sh: build + deploy the six new info-*.html pages.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- 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.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Shared header/footer/chrome (src/header.html, src/footer.html, src/chrome.js)
now on every page: editor (header above its app toolbar), player, teacher,
stage, micro, showcase, embed. chrome.js defers to DOMContentLoaded so the
footer version stamps regardless of placement. Player's fullscreen toggle
relocated out of the header to a floating control.
- Open = Info: each form-factor page is self-contained — a more-detailed
description (.about) + an expandable "Spec & BOM" (<details class="spec">,
hidden in embed). info-*.html retired; build/deploy/README updated.
Next: teacher-style dimensioned front + top/side views + loading panels for
Stage, Micro and Showcase.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Concepts is now the landing (/): index.html is the form-factor gallery with the
LIVE widget embedded in every box (editor/teacher/stage/micro/showcase/initial),
on the shared header/footer. concepts.html retired; every "Concepts" link → /.
- New shared chrome partials src/header.html, src/footer.html, src/chrome.js
(assembled by build.sh) + .site-foot / details.spec styles in base.css. Applied
to the landing + showcase this pass.
- Showcase redesign per spec: the pendulum bar IS the display — each lane's
subdivisions/accents ride along the rod as moving RGB light (all meters combined);
transparent outside the body (no black window); a printed tempo scale on the
vertical axis with a draggable weight to set tempo; start is an external button
(the real unit starts when lifted from its holder).
Next pass: roll the shared header/footer onto the remaining pages (incl. the editor
header-above-toolbar), merge Open=Info into one page per form factor with the
expandable Info & BOM, and add teacher-style dimensioned views to Stage/Micro/Showcase.

Sync: the visual playhead now advances on a latency-compensated clock
(currentTime − outputLatency||baseLatency) so the on-screen pulse lands when the
click is HEARD, not when it's queued — previously the visual could lead the audio
by the output buffer / Bluetooth latency (up to ~a subdivision). Applied to
editor, player, teacher, and the new pages; also bound the visual queue (vq trim).
No data races: single-threaded; only the rAF draw touches vqPtr/currentStep, and
each vq entry carries the exact scheduled time of its sound.
stage.html — foot-pedal stompbox: two heavy footswitches (Tap=tempo / hold=start-
stop, Next=item / hold=prev), 1/4" expression-pedal input → tempo sweep, big
floor-readable RGB beat light + angled TFT, analog instrument pass-through.
showcase.html — pyramid display piece: an RGB-light pendulum easing to each beat
plus per-lane segment rows showing subdivisions/accents/mutes (canvas).
Both: dual USB-C (data+power and power-thru) to daisy-chain off one source.
Wired into embed.js (stage, showcase variants), build.sh, deploy.sh, the
concepts gallery + landing cards, info-stage.html (~$52) + info-showcase.html
(~$39) with BOMs, and the README.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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).

The site now opens on a proper front door: a hero (logo + tagline + pitch),
an "Open the Editor →" CTA, and form-factor cards (Editor, Stage, Micro, Embed)
linking out to each page + info. The PE-1 editor app moves from index.html to
editor.html; every "Editor"/"Open" link, the embed.js editor variant, and the
editor's own brand-logo (now → /) are repointed. build.sh + deploy.sh build and
publish both index.html (landing) and editor.html (app).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Each form factor now has an information page (purpose + live embedded widget),
with priced BOMs only on the buildable hardware (Stage ≈$59, Micro ≈$28):
- info-editor.html / info-initial.html — purpose only (web app / concept)
- info-stage.html — purpose + the priced BOM moved out of stage.html
- info-micro.html — purpose + a new ~$28 practice-unit BOM
stage.html drops the BOM panel (+ its .bom CSS) and gains a "Spec & BOM" link;
the shared .bom/.sub table CSS lives in src/base.css. "Info" added to every
page nav and to the concept cards. Wired into build.sh + deploy.sh.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Every form factor supports ?embed=1: a head flag (set on <html>, no flash)
strips the site chrome (base.css [data-embed]) + page-specific panels, leaving
just the widget, and posts its height so the host can auto-size it.
- Config/settings string preloads via the existing #p=/#sl= hash. Added that
hash handling to micro.html (it previously only loaded built-in tracks).
- New embed.js loader: <div data-varasys-metronome="micro" data-patch="…"> + one
<script> → an auto-sizing iframe to <page>?embed=1#p=…. New embed.html documents
it and dogfoods a live embedded widget.
- "Embed" nav link added across pages; build.sh/deploy.sh build embed.html and
serve embed.js.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Shared site header in src/base.css (.site-head/.site-nav/.brand-logo + theme-
aware logo + .tbtn). Applied to player/stage/micro (replacing their text
topbars) so the VARASYS logo + tagline + Editor/Concepts nav is on every page.
- Rebrand the editor: "Stackable Metronome" → "PE-1 — PolyMeter Editor" (title +
h1), with a Concepts link in its header.
- New concepts.html — the PolyMeter Concepts library: cards for the editor and
each form factor (PM-1 Initial/Stage, PM-µ Micro) + a "more coming" card.
- build.sh + deploy.sh build/deploy concepts.html; deploy.sh now loops over pages.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Rename player-asbuilt.html → stage.html (the pedalboard build). Update
build.sh + deploy.sh (deploy now also removes the old player-asbuilt.html
from the web root) and the cross-links in player.html / stage.html.
- New /micro.html — a stripped-down home-practice metronome on the same RP2040
firmware. Hardware is just: ONE depressable scroll/rotary encoder, a red
7-segment LED display, a speaker, and USB-C for power. The encoder does
everything: spin = tempo, press = start/stop, hold + spin = switch track
(the LED shows the track number, with BPM / TRACK / ▶ indicators). Tracks =
the editor's seed grooves flattened (23). Shares src/engine.js, setlists.js,
base.css; synth-only; steady practice loop (ramps/bars ignored).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
New /player-asbuilt.html showing the PM-1 with parts you'd actually solder
for an RP2040 build, alongside the idealized /player.html:
- 128×64 MONOCHROME OLED (SSD1306 class): rendered as a true 1-bit
framebuffer — drawn, then thresholded to crisp on/off pixels and scaled
with image-rendering:pixelated — so the cramped real layout is honest
(position / big BPM / grouping / scrolling name / bar·beat).
- Fixed 16-px WS2812 ("NeoPixel") RGB beat bar on a strip PCB: lights the
first beatsPerBar slots (cyan downbeats, amber group-starts, dim others),
the rest dark — showing the fixed-count hardware honestly.
- EC11 rotary encoder you actually turn (wheel / vertical drag) for tempo,
tactile buttons, MAX98357A-style speaker grille, USB-C, PWR LED, matte case.
Shares the same firmware via src/engine.js + src/setlists.js (same seed set
lists, same scheduler); only the panel rendering differs. The device is fixed
dark hardware; the page chrome follows light/dark/system. build.sh + deploy.sh
now assemble/serve all three pages; player.html links to it ("As-built ↗").
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Both index.html (editor) and player.html (hardware-player mockup) now pull
their common code from src/ via a new build-time include marker
(/*@BUILD:include:src/…@*/), resolved by build.sh:
src/engine.js — audio voices (DRUMS×30), Web Audio scheduler primitives,
and the share-language codec (patch/set-list encode+decode)
src/setlists.js — SEED_SETLISTS, so the player ships the SAME default set
lists as the editor (player BUILTIN = SEED_SETLISTS)
src/base.css — reset + VARASYS brand palette + type stack
The editor inlines the CC0 acoustic samples; the player passes an empty
SAMPLES object and the shared playInstrument falls back to its synth voices,
so the device stays faithfully synth-only. Each app keeps its own state
globals, setBpm, advanceMaster/scheduler, and UI. ~400 lines of duplicated
engine code removed; the player's favicon is now the shared @BUILD:favicon@.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The source index.html now keeps small @BUILD:* markers instead of the
~250KB of base64 blobs (audio samples, logos, favicon), which move to
assets/. build.sh inlines them into a self-contained dist/index.html
(+ dist/player.html); deploy.sh runs the build first and serves dist/.
dist/ is git-ignored. Keeps the single-file deploy while stopping the
samples from eating the editing budget.
Also reframe the main page as the full web app (it is not a mockup —
only the play-only player.html device is): drop "Mockup" from the title,
the source comment, and the README intro; add Build/Files docs and
correct the "no build step" claim.
