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.


- 4 synth engines, 4 layers per voice
- Granular, FM, Additive, Subtractive
- 8 FM modes, layers as operators
- Granulate Samples or Live Audio
- Up to 20 grains per layer
- 1 modulation matrix per layer
- 2 EG’s per layer
- 1 filter per layer and a master filter

- 4 LFO’s with 5 modes
- Arpeggiator with 5 modes
- Delay and Reverb FX as layer send
- High Quality Sample Bank
- Built-in Audio Recorder
- MPE Compatible

Start with FRMS built-in library of samples, load your own, or even granulate live audio. Stack up to 4 layers of synthesis, with independent envelopes and modulation to create unique sounds with movement.

FRMS includes Imaginando’s Cloud Sync functionality (requires Imaginando account) so you can store and share your creations across devices with ease. Capture sounds wherever you are, then refine them in your studio, keep your creativity with you, wherever you go.

Sounds great, but needs work

This is a very creative synthesizer ap. The sound quality is very good. It has a rich set of features, and despite that feature set it is pretty easy to use. However, it appears to be unfinished. I can't get the 'chord' feature to work at all. Am I wrong? (If it works, it is far from obvious HOW to activate it). The on-screen keyboard seems locked into a chromatic scale, and unlike the desktop option, there is no way to import your own sounds to feed the 4 (!) granular monsters.

But ...it's a new ap at this point (March of 2020) and perhaps the developer will take care of these shortcomings soon.

(iPad Pro, 12", iOS 11.2.1)

Great potential

Really great interface with rich potential and I love that we have 4 layers to play with. It a bit rigid in it editing features but hopeful of future developments. With that said here is some of my insights.

.1 Needs more voices

.2 Pinch and zoom edit for waveform

.3 Size and offset should update when highlighting and selecting part of wave onscreen to match. (Much easier editing process)

With that, this app gets a ***** 5 😊

Yummy audio goodness

Imaninando super fan over here ..own everything but a shirt.

Get this not because I say so but because it’s a monster.

Could use a bit of optimization as it lags on older technology other than that it’s solid and a great diversification of the product line.

Maybe we will see a DRC 2in the near future!

Developer Response ,

Hey Super-Fan Rian! Thank you for your exceptional support! We hear you re optimisation, FRMS is a very hungry monster, so getting every little performance boost we can is important to us. Like DRC once was, FRMS is very much at the start of its journey, and we're so pleased you're riding it with us.
