Rhythm Ace vs Orbeat

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.

Orbeat is a drum machine in the round. Instead of a grid, your rhythm lives on a glowing mandala — concentric lanes of light that orbit a single play button. Tap the rings, watch the playhead sweep, and feel the groove move. Built to be played, not programmed. Open it and you're already making beats. A CIRCULAR SEQUENCER — UP TO TWELVE LANES Six lanes wrap the screen as rings, and the circle can grow to twelve: the mandala opens a second page of rings in its own electric color set, so every lane keeps its full size. Tap to place hits, lock a lane you love, mute and solo as you build the groove layer by layer. The whole pattern turns as it plays. FOUR DRUM KITS Classic, Acoustic, Glitch, and 8-bit — one tap reskins every voice while your pattern stays put. From clean and punchy to broken and chiptune. BRING YOUR OWN SOUNDS Build a custom kit and drop your own audio into any lane — WAV, AIFF or mp3, up to ten seconds, played at its original pitch and in stereo. Imported samples run clean to the output, while the lanes you leave alone keep their synth voice, so a hi-hat you recorded yourself sits right next to Orbeat's own drums. Your first custom kit is free. GENERATORS THAT SURPRISE YOU Roll the dice for an instant pattern, or use Euclidean rhythms to spread hits evenly around a ring. Like what you hear? Tap the ring to write it in and edit by hand. MAKE IT BREATHE, MAKE IT DRIFT Add swing to push the feel off the grid, draw velocity per step for accents that live, and pan each lane across the stereo field. With Probability, hits fire by chance; with polymeter, each lane gets its own length so the phases drift in and out of sync. TAKE IT ANYWHERE Bounce any loop to a stereo WAV — named with the beat, its length and its tempo, so it still makes sense in your DAW next month — or run Orbeat as an AUv3 instrument with MIDI in & out — sequence other instruments, or play Orbeat's lanes from your host's piano roll inside GarageBand, AUM, Logic, and other AUv3 hosts. Standalone, play the pads live from any MIDI controller and sync the whole groove to external MIDI clock.
