Pads are now 3-state instead of on/off: click cycles accent → normal → mute. Default keeps the first step of each beat accented (the rest normal), so existing grooves are unchanged in feel; legacy on/off masks migrate (on-downbeats → accent, on-subs → normal). - Audio gain is driven per step by level (accent 1.0 / normal 0.6); the old auto group-start accent is replaced by explicit per-step level. - Swing: "swing 8th / swing 16th" subdivision options apply a triplet (2:1) long–short feel to even subdivisions (per-lane). - Share language: pattern uses X (accent) / x (normal) / . (mute), and the sub token takes a trailing s for swing (e.g. ride:4/2s). The default-accent pattern is omitted; legacy x/. still parse. - Demos: "Swing ride" and an accents example.

Browser mockup / simulator for the Pi Pico metronome.
|
||
|
||
DESIGN: a basic metronome (tempo / volume / start-stop) PLUS an arbitrary
|
||
number of "meter lanes". Each lane is its own little metronome with a
|
||
grouping (e.g. 2+2+3), a subdivision, and a sound. All lanes share the global
|
||
tempo; layering lanes with different groupings/subdivisions is what creates
|
||
polymeter / polyrhythm — no special "voice" or ratio mode required.
|
||
|
||
Functions marked PORTS TO FIRMWARE carry over to the RP2040 with little change.
|
||
Web Audio's look-ahead scheduler stands in for the hardware timer.
