User Reviews

FRMS is praised as a deep, flexible granular synth with four engines that can be oscillators or sample grains, enabling expansive sound design. Users repeatedly cite low CPU use, rich textures, and a strong preset/expansion ecosystem, plus the ability to import their own samples. The app’s creativity and variety, along with active developer updates, are also highlights. Common complaints focus on stability and bugs (crashes, crackles, mic feedback issues), limited Bluetooth/MIDI support, and at least a perception that the price is high for the features. Overall it’s highly recommended for serious sound design, with caveats about reliability and cost.

Pros

Powerful four-engine granular architecture that can run oscillators, samples, or a blend for extensive sound design.
Low CPU usage on iOS, allowing dense patches without taxing performance.
Ability to import your own samples and access a robust suite of presets and expansion packs.
Creative, inspiring textures with a unique, cinematic character that stands out in iOS synths.
Active developer support and ongoing updates, including HD UI improvements and cross‑platform features like VST3 support and desktop syncing.

Cons

Stability and bugs: crashes, audio crackles, and occasional issues in DAWs like GarageBand.
Bluetooth and wireless MIDI support is missing or unreliable.

This one is probably gonna be one of the most useful tools in a musicians toolbox, with mindboggling possibilities and beautifully complex sounds with an almost effortless worksurface. This developer delivers on this and all his other apps especially the synth ones like this and the drc.

I love this synth because it has such a unique sound, and it works really well as an AUV3, including in BAM, which you should also check out.

This is the granular synth you’re looking for! I have almost every one on the App Store and this is the one I pull up the most. Incredible sound design potential with 4 simultaneous engines that can be oscillators or sample-based grains, or a blend of both. Worth mentioning too that I bought 4-5 of the preset packs and they did NOT disappoint! Creative and inspiring right out of the box. All hail FRMS!
