## FRMS Reviews in United States

### ***** "Finally a desktop-grade Granular on iOS"
iOS has about 3 or 4 apps available on its platform that utilize Granular, but FRMS stands up there with FM features, four layers, and a modulation matrix. Since its launch in 2020 Imaginando has continued to breathe life into their Granular flagship, including advanced UI resolution for HD screens, a performance boost, and VST3 support. It’s also available on Android, something few iOS developers have the time to invest into. Overall it’s one worth adding to your repertoire whether you’re on desktop or iOS. Here’s to a productive 2025 for Imaginando. 🎊
-- 3rdPersonProductions, 2025-01-01

### ***** "Check out the Foley voices (in-app purchase)"
It’s hard to find something that stands out in the iOS environment. There’s just too much good stuff. However, I have a fondness for this company, they are really engaged and creative! 

For me, the presets made out of Foley samples make this app. Not only is it encouragement to make your own, it’s also an acknowledgment that not everyone wants to learn everything about every app. Sometimes it’s all about finding something easy to use that speaks to you. Thanks.
-- Synth Dabbler, 2024-10-11

### ****- "Doesn’t work over Bluetooth. Expansions cost too much."
I try to play this over my Bluetooth amp for a simple drone and it never works. You can’t disable the microphone either. Its automatically on but not really on it just gives a bunch of feedback without picking up a signal.

Still to many bugs with this software. 
Audio won’t play over headphone jack either. 
Please fix the mic issue. There is no mic off button so the app screams and feeds back into itself immediately upon launch.
-- BansiPlayer, 2024-10-03

### ***** "Yeah"
Yeah this is quickly becoming my favorite synthesizer! everything this dev puts out is pretty awesome!
-- BenPitt31177, 2024-09-23

### ***** "Sonic powerhouse."
total beast of a synth and the iap are actually worth it.
-- Mesmertron, 2024-06-10

### ***** "Amazing"
Truly one of the best (and weirdest) apps the App Store has to offer. 100/10
-- hotstrange, 2024-06-08

### ***** "Honestly my Favorite"
On the Forums you see a lot of desert Island apps, This is mine, this Synth just keeps on giving. Thank you Team, Happy Birthday, you have a customer for life.
-- drrabbitfoot, 2024-06-06

### ***** "Excellent"
This is great very adventurous it takes my mind to the outta limits this app is for the creative soul looking for something different 
Love the pads
-- Speller Littlewing, 2024-04-01

### **--- "it’s fun but not even remotely close to worth the price"
you can get the same thing for much cheaper. I don’t know why the maker would try to price gouge with this product. save your money and get five other synths instead.
-- Futureretiredlawyer, 2024-03-04

### ***** "Great granular app"
I use a lot of different synth apps and granular is something that I have recently gotten more involved with. I have all of Imaginando’s apps and each one is amazing to work with. FRMS stands out from most of the granular I have used with ease of use and the different add-on packs as well as being able to drop in my own samples and the continuity of creation with the desktop app where I can pick up where I left off on my i-devices.
-- lofidelityrockr, 2024-03-01

### ***** "Super powerful synth"
Would like to see some performance/stability improvements though
-- Lemon Berries, 2023-11-25

### ****- "Didn’t mean to buy this"
Apple won’t stop spamming my card… :/
-- Elizabeth LeTourneau, 2023-11-21

### *---- "No Bluetooth & No Customer Service"
FRMS won’t work with Bluetooth. Sent a couple of futile emails to developer. No resolution. They never got back to me with solution. Only line: nobody else has this issue. On the contrary, I see other people do have this issue. Very disappointed, especially in the customer service.
-- BravoNikko, 2023-10-16

### ***** "Creative"
This is a Very Creative App, I use it A lot in my music production
-- Musacman2, 2023-08-26

### *---- "Doesnt work if opened while bluetooth is connected"
I was excited to try this but im disappointed to have spent so much for it to lack such basic functionality. Maybe another app does it better.
-- 666?!?!?, 2023-08-13

### ***** "FRMS the Music!"
Almost nothing you can not do with Granular/FM.
-- Eriptron, 2023-07-10

### ***** "Insanely Good"
Granulated sugar.
-- EthanGross, 2023-06-10

### ***-- "freakin keeps crashing"
Good app just crashing in GarageBand, UPDATE IT FIX IT KEEPS CRASHING AND AUDIO CRACKLES IN GARAGEBAND, MAINLY WHEN THERES A LOT OF CHORDS PLAYING
-- SxucyX, 2023-03-19

### ***** "ABSTRACT ART"
Beautiful abstract synth for those powerfully weird soundscapes that other synthesizers and musicians don’t make.
-- Groovy Rob, 2022-11-20

### ***** "Deep and awesome"
Don’t listen to the negatives, especially the religious weirdos with no actual critique. This thing is a tweaker’s dream, with a slick and intuitive UI, and is useful for many genres. At this price, it’s a no-brainer.
-- GorgorothX, 2022-11-19
