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

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.

The Model 15 App requires Big Sur version 11.0.1 or later to work.

Truelly wonderful app like all they make!

Modular madness,...but I wold like to see rack options and a ring modulation rack along with a drive feedback like on the sub 37 .or a modular tube distortion drive along with it all as a modern modular option format. Maybe a modern delay with LFOs with maybe a cross modulation wheel somewhere would be nice,..and a waveform options like on there bad boy monster mooger fooger delay That would be a wonderful evolution option. Please hire me for beta testing if there is a need. Would love to test out real systems as well and help in any design ideas or programming positions. I absolutely love everything Moog! Please make a delay like that more purchase friendly maybe a small footprint design or a Bluetooth guitar fix line like Zoom made. Might as well harness the full power and potential like you do on the new analog emulations like on this 15 system it’s wonderful what has been going on. They are brilliant although keeping your analog line as well would broaden the spectrum because secretly I think we all would like to have a analog pedal it’s just not as accessible as we want and could use some breaks into the no credit check payment plan options available today. But for now many of us would go for a digital pedal that is Bluetooth and affordable if analog must stay pricey. Here’s a Cheers to Moog! Well done!

Dang it iOS

Thanks for response, yeah, Apple really needs to figure some things out. I’ve had nothing but frustration trying to use iOS as a serious tool, from issues like the cpu usage you described, to type c hubs working/not working completely randomly. I’ve wasted a lot of time and money on this iPad. I bought it to integrate into my studio, but it’s done nothing but dead stop workflow over and over, like almost every time. Started using windows again for most audio/recording needs. It’s a shame too, this hardware is fully capable. They tell me I can’t get a refund because it’s my own fault that I waited too long to see if Apple could resolve issues, so now stuck w a 12.9 inch overpowered toy that can’t be trusted to work properly under any circumstances. Sorry for my original review, it probably wasn’t fair, and now a few apps not working properly is least of my concerns, now it’s hardware issues, random resets, randomly “not charging” randomly makes my audio interface and midi controllers have seizures, under no cpu load too. Can’t narrow down these issues they are so random and completely solve themselves then return a day or 2 later.

Developer Response ,

Sorry for your troubles. We are collaborating with Apple to resolve these issues. Sadly it seems like with the newer devices, iOS slows down the speed of the CPU when some applications are active. There doesn't seem to be a way for us to influence that, so Apple engineering is looking into it. Please bear with us as this is being sorted out.

Update: we saw your edit, and we can only tell you that three major bugs prevent us from updating our applications. These bugs have been acknowledged by Apple and their engineering teams are working on it. Our apps use different technologies than most other apps (for instance Metal), this causes iOS to behave differently. We actively maintain and work on our apps all the time, but sometimes we are not able to work around certain platform issues and have to wait for Apple to address them.

Simply the best.

I plan to write a full review, but it’s amazing. The sounds you discover 😳that they are related to scores played in film and TV in the many sound settings. Same arps, same feel, same wow. 👊 Just started playing. Too many good words to describe it would sound like gibberish with slobber thrown in. My mouth hasn’t stopped talking about it with friends,🤩🙄 , or figuring out the infinite ways to make a sound, and bend it to your will🤓Bob did create the Monster of Sound. Unlike any other instrument in the modern age, (here it comes) the Moog formulated version of the synthesizer instrument is the most flexible, most creative due to unlimited unknown sounds within the hundreds of thousands of overlap and waves of electrical signals that ping pong, across multiple LFO’s and VCO’s, from making a complete sound of a dolphin, or the docile nature of the bell tone, it’s Bob Moog’s mind that dwarfs the common instrument creator. Don’t hesitate, buy this one first.

“You will never master it, because it’s unattainable to humans, that’s what makes music so.” TM!

Yeah, I wrote that.
