Phaser Factory vs Rhythm Ace

GSi Phaser Factory is a versatile phase shifter effect in the likes of some famous guitar pedals such as the Phase 90, the Small Stone, and stuff like that. With Phaser Factory you can create your own phaser and even try to "clone" an existing model. Select the number of phase shifting stages, from 1 up to 20! Set the LFO width and offset. Configure the feedback chain, the output mix and the summing stages. The algorithm is simple and efficient, once you get the perfect vibe, save your presets. And if you're a plugin developer, you can even export a C++ Class that you can use in your project to play the exact preset you've created in Phaser Factory. Phaser Factory is not only a phaser, it's all of them.

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.
