App Description

FRMS is a versatile hybrid synthesizer that combines Granular, FM, Subtractive and Additive synthesis using a flexible layering system.

FRMS takes the interesting and exciting world of granular synthesis and gives it a musical edge by mixing it with FM synthesis to produce a wide variety of possible timbres, with a sleek and modern interface. From heavily-dense ambient drones, to glitchy mechanical beings, turn simple sounds into complex evolving soundscapes, with up to four layers of synthesis in any combination.


FRMS is available as a stand-alone app and AUv3 plugin only. No IAA audio support available.

FRMS is a CPU intensive app, therefore some devices with lower hardware specifications might not be able to play 4 simultaneous voices, resulting in possible audio glitches. The density of grains is the most significant aspect regarding performance. A 2nd gen iPad Pro is able to play all of the bundled presets with 4 voices.
