Per Mike's 'next set of drum apps' nudge after the kettle landed: four more rooms in one short batch.
## What shipped
- /drum-v12 · Pipe Organ. Sixteen keys (C4..D5#), three voicing stops (Diapason 8' / Flute 8' / Principal 4'), pedal-point toggle, tremulant and reverb sliders, a 4.5s cathedral convolver-reverb. The note doesn't end as long as you keep holding. Each stop is a different harmonic recipe; partials get ±4¢ random detune for the chorusy pipe shimmer. Stained-glass rose window above the keyboard, 21 brass-tipped pipes in graduated heights, a wood console with three pull-out stop knobs that light up when on. Multiplayer broadcasts type=organ. — PR #195.
- /drum-marquee · The smallest cast view. Single-line ticker. Each /api/sounds event slides in from the right as a colored row (time + chip + extra + pid), drifts left, fades over 16 seconds (28s for milestones). Twelve event types color-coded — drum, organ, choir, lounge, theremin, symphony, bells, daily, kettle, potato, milestone. Three palettes (1·2·3 hotkey): black, paper, sunset. F = fullscreen, M = hide chrome. Plug into a small TV in the corner of a kitchen. — PR #196.
- /drum-stickers · The binder. Twenty-four stickers, one per drum-hub surface, each with a shape (circle/rounded/square/pill/diamond), color, and glyph. Earned stickers in full color; unearned in grayscale + 65% opacity. Earning logic reads existing localStorage keys the surfaces already write — your binder fills in automatically on first load. Click an unearned sticker to visit the surface; it marks pc:drum-{id}:visited so the next time you come back the sticker fills in. No multiplayer, no chain, no mint — just a friendly local record of where you've been. Companion to /drum-trophies: trophies are formal and on-chain, stickers are everyday. — PR #197.
- /drum-radio · The room never goes silent. Auto-DJ at 96.1 FM. LIVE mode plays each /api/sounds event as a Web Audio synth hit (kick / snare / hat / bell / organ / pad recipes mapped per family). REBROADCAST mode kicks in after 12s of silence — loops the last 50 buffered events on a 4.5s tick with an ambient pad underneath. All audio synthesized in-browser; nothing streams from a server. Three knobs: volume, warmth (LPF cutoff), echo (convolver wet). Vintage dark-wood receiver aesthetic — brass dial, glowing red needle drifting on a sine sweep, BUNGEE display font for ON AIR / LIVE / REBROADCAST. Hit POWER, leave the tab open. — PR #198.
## What this batch does together
The pipe organ adds sustain to a hub that was mostly transient. The marquee + radio add passive listening surfaces — leave them open in a corner and the room makes itself a soundtrack. The sticker binder adds the cozy completion loop at the bottom of the trophies-and-mints stack.
Drum hub stood at 28 surfaces by the end of this batch. Three cast modes, four games, fourteen instruments, a kitchen with a kettle, a confessional — and now a radio playing softly through it.
