## What is ARP ODYSSEi?

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.

### 5/5 — Je dois repayer sur mon nouvel iPad

*2026-08-16, version 1.0.6*

Ne figure plus dans ma liste d’acat

### 5/5 — Must have

*2026-08-09, version 1.0.6*

What a creative machine. Make sure you have something to record the output in the moment because it will do amazing unpredictable things. Wish I’d found this sooner. hopefully patch cables coming in the future

### 2/5 — Arp Odyssei review

*2026-08-03, version 1.0.6*

Korg need to update their apps to AUV3 only a few of them are and this isn’t one great synth , but really it’s useless unless it’s AUV3

### 3/5 — dommage

*2026-07-30, version 1.0.6*

excellent son mais qu’en faire sans AUv3 ?

### 5/5 — Fantastico!

*2026-05-06, version 1.0.6*

Ho le registrazioni (anni80)del mio vecchio Arp e i suoni riprodotti con gli stessi patch su ODYSSEi sono identici! In più ha il Pad!

### 4/5 — AUv3に早く対応してほしい

*2026-04-11*

よく出来ていると思います（別売なのはRev1、Rev2用のスキンとプリセットパッチのみ）が、いまだにAUv3未対応なのが残念無念。早くGaragebandで使いたいです。

### 5/5 — My Favorite iOS Synth yet!!!

*2026-04-03, version 1.0.6*

Soooo good! Sounds warm and fat. Very versatile. Absolutely love this synth!

### 2/5 — AUv3

*2026-03-29, version 1.0.6*

So eine App ohne AUv3 macht nur bedingt Sinn.

### 4/5 — AUv3 Support Needed ¡PLEASE!

*2026-01-30, version 1.0.6*

Love the sound of the ARP ODYSSEi with it’s faithful re-creation of the ARP SEQUENCER but it’s high time KORG gives this beauty AUv3 support so we can plug it into a real DAW.

### 3/5 — FANTASTIC, But…

*2026-01-22, version 1.0.6*

The ARP Odyssey was my first synth, back in 1978. As someone who had the original hardware, and used it for many years, I can report that this thing sounds great. All the switches and sliders do what they’re supposed to, and the bits that KORG added (effects & sequencer) are fabulous. But there are some serious problems, which I have requested fixes for, and have never been addressed. #1: the EQUAL/ANALOG switch. This has no business being there at all; all the ANALOG setting does is simulate an out-of-calibration Odyssey. This is not “the unique character of the Odyssey”, it’s a flaw, which I spent considerable $$ to keep in adjustment while I had my Odyssey. In itself, this is not a problem; I just leave that switch on EQUAL. But that switch does not exist in the Lexington gadget, and it is locked into the ANALOG mode, with the result that any 2-oscillator sounds are progressively more out of tune the further you get from the center of the keyboard. #2: NO MIDI Program change capability. #3 NO AUv3 capability. If this stuff ever gets fixed, I’ll change my rating to 5 stars immediately. In the meantime I’ll try to make do. It still sounds fantastic…
UPDATE 4/3/2024: We just got the AUv3 update for Korg’s iM1, which is fantastic, and I am hopeful the ARP ODYSSEi will also get this update soon. Also hopefully my other issues mentioned above will be fixed. In the meantime, the ARP ODYSSEi is still a brilliant recreation of my all-time favorite synthesizer; I’m looking forward to using it much more, both within Gadget, and as an AUv3. Thanks, Korg!!!
UPDATE 1/21/2026: We recently got the AUv3 update for iWAVESTATION, and I continue to hope that the ARP ODYSSEi will also get this update soon.
