The legendary ARP sound, exquisitely reproduced in software.
ARP ODYSSEi - A mobile analog synthesizer for iOS.

The ARP Odyssey of 1972 has earned an unshakable position as a classic analog synthesizer. In 2015, KORG produced the ARP ODYSSEY, a complete reproduction of the original. The ARP genes that shook the worldwide music scene are being passed on, and its history continues.

The next platform for the ARP ODYSSEY is iOS. We want the unforgettable ARP sound to be easily available on a device that as many as possible of today's players can obtain; this resulted in the "ARP ODYSSEi" app for iPad / iPhone. Based on the revived ARP ODYSSEY, we used KORG's proprietary CMT circuit modeling technology to reproduce the analog feeling and sound of the original as closely as possible. We've also given it numerous enhancements that are possible only with software, such as long-awaited polyphony and built-in effects.

The real analog ARP ODYSSEY, and now the uniquely evolved ARP ODYSSEi, brings the universal fascination and inimitable sound to every device.

* 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 ]

- Faithfully models the circuit of the ARP ODYSSEY: The circuitry has been reproduced using KORG's proprietary CMT (Component Modeling Technology), developed over the years starting with the KORG Legacy Collection.

- New functions to create all-new ARP sounds: Added a voice assign mode that allows you to play chords, an arpeggiator that can be programmed in detail like a step sequencer, and effects that can transform the sound in diverse ways.

- Get all three of the sought-after revisions: In addition to the standard design of the Rev3 with its black panel and orange silk-screening, you can optionally obtain the white-paneled Rev1 and the black-paneled gold silk-screened Rev2 designs, together with fifty new preset sounds that take advantage of the distinctive filters of those models.

- Produce music together with KORG Gadget: ARP ODYSSEi can be used in conjunction with the "KORG Gadget" music production DAW app that has won numerous awards around the world. If both apps are installed, it can be used as the "Lexington" gadget inside the KORG Gadget app.

Best iOS Synth by a mile in 2021

It took me forever to buy this, and I’m honestly shocked to say it is easily the most powerful synth I have in my collection, including the Model 15. Sorry Moog. You would never know what a beast this is just by looking at it.

The modulation and effects options on this really make it astonishingly flexible, particularly the sequencer. This thing can do it all, and can control nearly any parameter. You can combine and break the modulation pathways with just as much freedom as with a modular. Smartest design ever.

The synth itself sounds absolutely amazing, and the fact that you can choose a universal tuning setting (mine will be forever set to the beautifully unstable analog setting) is such a plus. There’s a great collection of filters and effects, and if you really analyze the presets you will quickly see you can do pretty much anything you want with it.

I do wish it had midi learn within the app. I was able to program the cc numbers into my launchkey 61, so it is fine, but that was rather tedious. Absolutely worth doing though.

So this is a genuine fully fledged virtual analog instrument that I wish I bought years ago. If I could only have one, this would be it. This could be my only drum machine too. Don’t miss out on it any longer.

Great sounds but needs more

This is a very good app, with tons of sounds and lots of control. The only problem is the Gadget doesn't have the original arpeggiator that makes some presets sound great, and I want to use it in songs within extra routing. Also, is there a solution for the silence if used with Audiobus and GarageBand? Either way, definitely a must, and you should check it out if it goes cheap. Also got the in-app purchased and they're good too. If you're wondering if you're going to pick between this and Module, get this first. Let's hope they update this with more presets like Gadget!

Awesome synth ,

Excellent, but problematic

I have just purchased ODYSSEi, and for the most part, really like it. It's more like a true analog synth, with respect to programming, than most of my other iOS synth apps. This doesn't make it one of my favorite apps, but in terms of workflow, it's pretty analog. I am not hugely enamored with most of the stock sounds, but in a matter of a few minutes, I was able to tweak a few to my liking. What I find odd is that in hardware, Korg is truly one of my favorites, but I find this to be far from true in the iOS Korg app world. Inside of Gadget, ODYSSEi runs under a different name, and appears to underwhelm, severely. First of all, user edits in ODYSSEi don't show up when it's opened up in Gadget, which makes it almost useless for me, with respect to Gadget. Secondly, almost all the arps don't work when the app is opened up in Gadget. What a bummer, Korg!
