Reviving a classic KORG analog synthesizer.
The iconic 4VCO synthesizer, reborn on iOS.

The Mono/Poly analog synthesizer appeared in 1981 at the same time as the acclaimed Polysix. Not only was it a fat-sounding four-VCO monophonic synthesizer, it featured a revolutionary design that allowed it to also be used as a four-voice polyphonic synthesizer, which helped cement its legendary status.

The long-awaited “KORG iMono/Poly” iPad/iPhone app completely reproduces all features of the original Mono/Poly. Four VCOs and a rich array of modulation allow a wide range of detailed sound design. New functionality such as two multi-effects units and eight virtual patches are also provided. In addition, the seamless integration that you expect from KORG’s iOS apps will fit perfectly into your music making process. The Mono/Poly has been reborn for today’s world, bringing you a unique and legendary sound.

* Due to differences in CPU speed of iPads / iPhones, iPad 3rd gen/2/iPad mini/iPhone 4s are not supported, only iPad Air/iPhone 5s or later is recommended.

[ Features ]

• Deep 4VCO sound. A complete reproduction of the classic Mono/Poly
The Mono/Poly synthesizer featured four VCOs, a dedicated envelope generator for the VCF, and also sync and cross-modulation, earning it a reputation for its detailed sound-shaping potential and its distinctive character.

• Powerful virtual patches, and the latest presets to catch the scene
Eight virtual patches provide the ultimate expansion of the Mono/Poly’s distinctive sound-design potential. Two multi-effect units are also provided, allowing you to create complex and broad-ranging sounds with complete freedom.

• Quick access to all panels
Although iMono/Poly provides a vast number of parameters, it’s designed with a screen structure that provides quick and seamless access to all of them. With a single tap, you can rotate between the main synth & key assign screen and the virtual patch & effect screen. There’s no need to open individual screens for specific functions, or to move back and forth between them.

• Produce music in conjunction with KORG Gadget
iMono/Poly can be used in conjunction with “KORG Gadget,” the music production DAW app that has won numerous prizes within Japan and around the world. When you install both apps, iMono/Poly appears as the “Montpellier” gadget within KORG Gadget.

Great if u use Gadget, not a great investment if not.

This is a great synth, top notch as is Korgs other IPad/IPhone synth, if you have or plan on using Gadget, or using it as a stand alone in a live situation, otherwise I would say it’s a good investment, unless Korg makes it an Audio Unit like they did with Electribe Wave. Bottom line is There isn’t a future for IAA apps now. If your workflow includes Audiobus, it could still have a life line but even still, I prefer using Audio Units inside of Audiobus and I actually prefer not using a 3rd party apps to get my sounds to my Daws. If Korg actually read these reviews I hope they make this an AU because it would bring soooooo much more to the Mobile audio production platform and I’d recommend this app 100%.

Almost there...

I already own a *lot* of synth apps, including most of Korgs, but this one I couldn't say no to...and I'm glad I didn't. Very inspirational to play and sounds really great.

This would be 5 stars if I could access my user patches within Gadget's companion device Montpellier...hopefully a quick patch fixes this oversight...

Would also be killer if I could have a mod destination for the VCO Mod Type...I love switching between these but would be great to put an LFO to that...

The best- but the greatest would be

Adding AU to this already go to app,
My production increased by 1000 once I got this app,
Can’t see myself making beats on any other app as much I do Gadget, I LOVE this app more than I can explain,
It helped me produce like I want to, because I make beats fast, simply because I don’t produce by instrument choice, I produce by sound, it pattern sounds together no matter the instrument, and I’m great at it, thanks to the enormous amount of sounds gadget has, I’m in sound heaven
