## What is Model 15 Modular Synthesizer?

The Moog Model 15 App is the first Moog modular synthesizer and synthesis educational tool created exclusively for iPad, iPhone and iPod touch.

Each facet of the Moog Model 15 modular synthesizer has been meticulously recreated in this application to ensure the power and transcendent sound quality of each module remains intact. The character, harmonic complexity and mystique of the Moog Model 15’s modules, from the legendary Moog 921–series oscillators and 904A Low Pass Filter, to the coveted 907 Fixed Filter Bank have been painstakingly preserved. 

In order to develop the most immersive and expressive modular interface possible, the Model 15 App has been designed utilizing Apple’s new Metal advanced graphics engine. This ensures that all zooming, panning and modular patching throughout the application feels completely natural, something that would have been impossible otherwise.
 
The Model 15 App features both monophonic and 4-voice polyphonic operation is easily commanded via 4 seamlessly integrated controllers. Simple swipes and taps provide instant access to a traditional Moog keyboard, 1150 ribbon controller, 8-step sequencing arpeggiator and the award-winning Animoog keyboard with 22 built-in scales and polyphonic modulation capabilities.
 
Also included are extended features which expand the capabilities of the app beyond the traditional offerings of the hardware Moog Model 15. These include total MIDI integration, assignment for external control, use as a MIDI controller, dedicated Audio Bridge and MIDI Bridge modules, looping recorder module with overdubbing, a master ping-pong delay module and a new extension cabinet that includes additional amplifiers and voltage-controlled reversible attenuators that can be used for effects like ring-modulation.
 
Because the Model 15 App utilizes Apple’s Metal technology, only 64-bit devices are supported. Compatible devices include iPhone 5s or newer, iPod touch 6 or newer, iPad Air or newer, and the iPad Pro.

The Model 15 App requires iOS version 12.4 or later to work.

### 1/5 — Ne figure plus dans ma liste d achat je dois

*2026-07-30, version 2.4.4*

Repayer dans mon nouvel iPad

### 2/5 — Nice, but…

*2026-07-14, version 2.4.4*

Sounds beautiful! On a newly bought iPhone I wanted to restore purchases inside the App but it won’t succeed. In the AppStore it shows the packs I already bought and can’t buy twice.

### 5/5 — Great Modular Fun

*2026-07-05, version 2.4.4*

An amazing app. Incredible value. A little frustrating not being able to see the whole screen at one time, but the power of this synth and the flexibility. Its game changing (my first mod synth - very excited).

### 3/5 — Broken expansion store purchasing

*2026-06-12, version 2.4.4*

“Restore purchases” doesn’t restore purchases… I have to go through each expansion pack I bought and actually buy it, double click the power button for confirmation, and then have it tell me that I have already purchased this. But I don’t know if I did or didn’t before buying it… so inevitably I would have to buy all of them to ensure they are installed.  This is either genius evil work or sloppy coding. Come on, Moog, fix your app!

### 3/5 — Realistischer Moog-Sound

*2026-06-08, version 2.4.3*

Ich kenne den originalen Klang eines Moog System 15, 35 oder 55. Dieser virtuelle Nachbau trifft den Grundcharakter sehr gut. Auch das freie Patchen macht Spaß und fordert heraus. Die grafische Oberfläche ist realistisch. Ich wünschte mir, dass zusätzliche Module als Add-On zugekauft oder kostenfrei hinzugefügt werden; da wären z.B. der Bode-Frequenz-Shifter, oder das Sequencer-Modul, oder .....

### 3/5 — Restore purchases not working.

*2026-06-02, version 2.4.3*

restore purchases not working.

### 1/5 — Wird die App noch supported?

*2026-06-01, version 2.4.3*

Leider blieb meine Anfrage an den Support der App gänzlich unbeantwortet. Aktuell werden keine bereits getätigten inApp Käufe innerhalb der Applikation angezeigt die Wiederherstellung über die App funktioniert auch nicht

### 1/5 — Problem with iOS 26.4

*2026-06-01, version 2.4.3*

For a long time the restoration of in-app purchases in all Moog applications no longer works. It seems impossible to contact support and Moog has completely ignored the problem for months. It seems impossible that Moog doesn't read the reviews on the App Store. I will continue to leave reviews until the problem is solved.

### 1/5 — Can’t Exit

*2026-04-25, version 2.4.3*

Great sound. This and the Model 15 cannot swipe out of the app — the user gets locked in and has to hack a way out through settings

### 5/5 — Top Quality Synthesizer

*2026-04-25*

I loved the purchase !
