The parallel agent's full session, committed now that it's solo: - Grammar: flam/drag/roll ornaments (f/F d/D z/Z, per-lane orns channel) across src/engine.js, pico-cp/pico-explorer/pico-scroll app.py, pico/main.py, rust/track-format, + golden vectors / conformance (tests/, rust/track-format/tests). - Live-sync deep-sync: SysEx 0x44 SLSYNC + 0x45 LOGSYNC (docs/livesync-protocol.md, src/livesync.js). - PM_E-2 notation: web engine (pm_e-2.html, build/deploy/index/embed wiring) + Rust device port (pm-ui draw_notation rewrite + LaneView.groups, pm-kit ViewMode, uisim notesim). Verified: node tests/run.mjs 47 pass / 1 known; ./rust/run.sh green; pm-kit firmware + uisim compile.

# VARASYS PolyMeter - PM_G-1 "Grid" firmware (CircuitPython edition)
|
|
# Pimoroni Pico Scroll Pack (PIM545): a plain Raspberry Pi Pico (RP2040) + a 17x7 single-colour
|
|
# white LED matrix (IS31FL3731 over I2C @ 0x74) + 4 buttons (A/B/X/Y). No touchscreen, no joystick,
|
|
# no speaker. Audio is over USB-MIDI (the editor's "Device audio"); an OPTIONAL piezo on a free GPIO
|
|
# can be enabled below.
|
|
#
|
|
# Sibling to PM_K-1 (../pico-cp/) and PM_X-1 (../pico-explorer/). SAME engine, SAME program-string
|
|
# grammar, SAME programs.json, SAME web editor, SAME live-sync protocol. The Grid build is READ-ONLY
|
|
# on the device (no on-device beat editing); editing happens in the web editor with Live sync on.
|
|
#
|
|
# The 7-row x 17-column matrix is the editor's lane x step pad grid in miniature: each lane is a row,
|
|
# each step a column, brightness encodes accent / normal / ghost; a moving playhead column tracks the
|
|
# beat. Three views (button B cycles): Grid, Pendulum, BPM.
|
|
#
|
|
# WHY CIRCUITPYTHON: the board mounts as a USB drive (CIRCUITPY) carrying this code + your tracks +
|
|
# an offline copy of the editor; edits in the web editor are pushed over USB-MIDI. Pinout in README.md.
