### 5/5 — Great

*2024-02-17*

My to Go Tool on every channel

### 5/5 — Still useful as IAA

*2022-05-02*

FLSM is not on the AU band wagon yet but I really like it. The IAA versions of the Kymatica fx are a perfect fit. They are stable, always work as expected and sound great.

### 4/5 — 🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨🚨

*2021-07-29*

Can this app be converted into audio unit ?? With an update

### 5/5 — I’ve always loved this iaa -

*2021-02-13*

please release the auV3 version soon so i may use with my favourite host (AUM)!!!

### 3/5 — Nice but no auv3 support

*2020-10-30*

You have to understand that you can only use one instance in your daw. The reason for this is the lack of auv3 support. The sound is good, it's generally easy to manage the settings, I wouldn't say it's perfect, but it's fine.

### 4/5 — Toller EQ dem ein paar Features fehlen

*2020-07-02*

Mir gefällt der PeakQ klanglich wie optisch gut - und freue mich sehr über den Spectrum Analyzer. Es fehlen aber leider ein paar Dinge wie zusätzliche, durchstimmbare Hi- und Lowpass Filter mit schaltbarer Flankensteilheit. Auch wäre es schön, die Shelf Filter auf Peak umschalten zu können und auch im Shelf eine regelbare Güte zu haben. Aber vielleicht gibts ja mal ein Feature Update..., - - dann gibts auch fünf Sterne!

### 5/5 — ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️

*2020-01-04, version 1.2.4*

A collection of exceptional plugins! Impressive quality and complete immersion in effects. A realism rarely seen in software of this category. I've been working in the business for over 30 years, and I've sat in front of an SPX 900/1000, or a Lexicon. Just fantastic! I recommend everyone!

### 5/5 — HYBRIDCELL Aus

*2019-11-16*

A great little app this. Always reliable when performing.

### 3/5 — Good bundle///auv3 please!!

*2019-11-11*

### 5/5 — Nothing else comes anywhere close

*2019-11-01*

To how well put together all these apps are
