PeerClock Metronome vs Rhythm Ace

PeerClock Metronome is a P2P-synchronized metronome for Apple devices. Just connect multiple devices to the same Wi-Fi — no server needed. All devices automatically discover each other and sync their clocks with ±2ms precision using NTP-style 4-timestamp exchange. Features: • Peer-to-peer — no master/slave, every device is equal • ±2ms clock synchronization • Wi-Fi only — no external server, no internet required • Auto-discovery — connect to the same Wi-Fi, that's it • Visual conductor path animation with brush-stroke style • Multiple time signatures: 4/4, 3/4, 4/8, 3/8, 6/8, 9/8, 12/8 • Live BPM changes sync across all connected devices • Built on PeerClock — an open-source P2P clock sync framework Perfect for musicians, bands, and ensembles who need synchronized timing across multiple devices without relying on cloud services.

Rhythm Ace is a faithful simulator of the Ace Tone FR-1 — one of the earliest consumer drum machines, built in Japan in 1967 and the ancestor of the legendary Roland rhythm machines. Every sound is synthesized in real time using classic transistor-style audio circuits — no samples, no loops. Just pure, characterful analog-era percussion the way it was meant to sound. Eight synthesized voices Bass Drum · Snare · Low Conga · High Conga · Cymbal · Claves · Cowbell · Maracas 16 classic rhythm presets Waltz, Bossa Nova, Samba, Rock, Swing, Foxtrot, and more — all faithfully recreated from the original FR-1 diode matrix. Authentic pattern combining Select multiple rhythm buttons to layer patterns exactly like the original hardware — the diode matrix OR-combines their steps, letting you build complex grooves from simple presets. Voice cancel controls Mute individual instruments on the fly with the dedicated cancel buttons, just like the original panel. Precision tempo control Large rotary knob for natural, tactile BPM adjustment. Sample-accurate scheduling Built on a lookahead audio clock for tight, rock-solid timing — no drift, no jitter. Whether you're a vintage gear enthusiast, a music producer hunting for retro textures, or just curious what the dawn of the drum machine sounded like, Rhythm Ace brings a slice of music history to your iPhone.
