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 9.3 or later to work.

What's New

Version 2.1.3

• Fixed the recorder 4-beat count-in with Ableton Link. When connected to Link, the recorder now blinks for a moment while the app is syncing to Link Tempo. Once in synced, the recorder starts its count-in as usual.
• Fixed an issue where disabling "Vertical Slides as Modulation" while playing the keyboard would keep the modulation active.
• Midi Bank Change was wrongly responding to CC0 only, while it should have been CC0 and CC32, with CC32 being the LSB.

You'll need a 12.9 iPad Pro and external keyboard


So this synth sounds great. And the skeuomorphic design looks good. It's just a UI that is not user friendly on a regular sized iPad. With the keyboard loaded the synth area is far less than half the screen. The labels are very small, and there is a lot of continual zooming and unzooming and panning required. And also there is a lot of loading and unloading of the keyboard to test the sound if an external keyboard isn't available. If I was already familiar with the interface from using an actual Model 15, then it might be okay (and surely not many of us will have had that chance). But to learn how to patch as I go is a real pain. As is trying to analyze how preset patches are put together. At the very least I would suggest updating with the option of a smaller keyboard, one that doesn't take up a third of the screen. Or more so an alternative digital interface that fits on the screen and functions more simply. Being a slave to the original look, while kind of a novelty, is just not that functional. And I am growing fatigued of this before I have even begun to learn how to program it.

Developer Response

Laarz, Thank you for your feedback on the Model 15 App. We'd like to address some of your concerns:

"You'll need a 12.9 iPad Pro" - The Model 15 App is compatible with multiple Apple devices -- many users are running the instrument all the way down to an iPod Touch

"UI that is not user friendly on a regular sized iPad." - The Model 15 App's user interface contains many gestures for quick navigation as well as a Side Navigation Bar for quick access to various aspects of the instrument. Take advantage of the Side Navigation Bar and Double-Tap gestures to greatly accelerate navigation. All gestures and navigation controls can be referenced in the Model 15 App's user manual.

"With the keyboard loaded the synth area is far less than half the screen" - Each keyboard can be collapsed using the Collapse Button or quickly swiped away and back using gestures.

Thank you for using the Model 15 App and we hope these tips improve your experience with the instrument.

Amazing app!!!


I have always loved Moog and was very excited when I found this app. As far as people complaining about needing a 12.9” iPad Pro, they’re just being picky and complaining unnecessarily. I have a 10.5” and 9.7” iPad Pro and it works fine. It is a soft-synth after all!!! 😏 To get all these great sounds for this low price is phenomenal.

I connect this app to my MacBook Pro via the midi configuration and control it thru Reason 10 and a Novation Controller. Everything works great. I play the sounds on my controller, record the midi, edit modulation and use the iPad for final tweaking/moving cables while recording the final audio. All around, it’s a must have app if you love moog sounds.

If you want more room you can by the USB to lightning adapter, plug in an inexpensive midi controller and play the keys that way, giving you a little more room to access the knobs/cables, etc.

Aliased, Yet Playable


Moog Model 15: The App has set out to do the impossible. It's not going to be possible for any software to ever avoid aliasing. That said, if you're willing to lay down your sword and give this experience a chance, you'll find it to be quite playable. And if you've ever played around with VSTs that attempted to model this kind of a synth in the past, you'll have a lot more fun and be more satisfied with the audio.

One of Moog's killer features in their iOS apps is the ability to touch a knob with one finger and as long as you don't let that finger off of the screen, you keep control of it. By doing that to a lot of knobs selectively over time one can gain a kind of invisible orchestra of control that just doesn't happen in the hardware world.

What would give this app five stars?
1. There's some sort of swipe action that switches between the keyboard(s) and the ribbon controller. Boooooo. Get rid of that. Y'all, that's where I'm trying to play this slip n slidey thing.

2. Legibility. I know the original hardware was black with white labels but perhaps an inverted color scheme would help? I agree that it's rough on the eyes sometimes. I borrowed a huge iPad pro from work and was amazed that the modules still didnt fit at a comfortable size. BUT the ability to "latch" a touch eases the frustration. Again, give it a chance
