Will be support AUv3 in next update ? ### 2/5 — AUv3 . . . tap tap tap, Hello? *2026-04-08, version 1.2.6* When is AUv3 being implemented in this and your other apps? ### 2/5 — AUv3 *2026-03-29* So eine App ohne AUv3 macht nur bedingt Sinn. ### 3/5 — 惜しい *2025-12-01* コルグガジェットで使って欲しいのは分かるが、AUv3にも対応して欲しい。 ### 4/5 — AUv3 プラグイン対応を希望します。 *2025-10-20* 2025/10/20時点では、AUv3 プラグインとしては、残念ながら使えません。 また、KORG Gadget で、Montpellier としてアンロックされますが、Montpellier は、AUM など他のDAW等でAUv3 として、読み込めません(一覧に表示されない)。 AUv3 対応されることを希望します。 iM1 は発売から9年ほどたって突然 AUv3 対応になったので、iMono/Polyも期待して待ってます。 **Developer response:** レビューありがとうございます。 現在、順次AUv3対応を進めておりますので、 ご要望にお応えできるよう今後も努めてまいります。 引き続きご愛顧のほどよろしくお願いいたします。 コルグアプリチーム ### 4/5 — Mrs de Korg: vous êtes bornés ou quoi! *2025-08-18* À quoi ça sert de nous mettre sous le nez des versions iOS sincèrement excellentes de vos superbes créations en vous obnubilant à ne pas vous adaptez à la manière dont 99% des « iMusiciens » travaillent: c’ est-à-dire avec les technologies AUv3 et/ou inter-app !!! Surtout qu’ en plus vous avez abandonnés la fonction WIST! Du coup, à part servir de versions diminuées et simplifiées dans Gadget, vos Polysix, Mono/Poly, iElectribe, iM1, iMS20, ,iDS-10, Odissei...etc sont condamnés à n’ être utilisés que chacun TOUT SEUL dans son coin. Comment je fais si je veux synchroniser ma boîte à rythme préférée avec iMono/Poly? Je ne peux même pas utiliser iElectribe! Un comble.. C’EST DU GRAND N’IMPORTE QUOI! Svp, je vous le demande à genoux: implantez au moins la fonction AU (Audio Unit) dans vos applis. Sinon iKorg c’ est fini pour moi. **Developer response:** Hello. Thank you for your review. We are so sorry that we haven't released AUv3 capabilities for this app yet. We have plans to implement it in a near future, and we hope on that day we can receive a newer and happier review from you. Best regards, KORG App Team ### 2/5 — Auv3 not support *2025-07-22, version 1.2.6* It's 2025 and the app still doesn't support Auv3 and I can't use it with grooveboxes and hosts. GIVE ME MY MONEY BACK!!! ### 2/5 — Cannot restore expansion pack or find store tab. *2025-02-03* Disappointing, and cannot find or use in Gadget. **Developer response:** Hello. Do you have any updates about this review? Please let us know. Original message: For this kind of request we strongly recommend you to contact our dedicated support channel, so our team can communicate quickly and directly with you: https://support.korguser.net/hc/en-us/requests/new Regarding the restoring, in the Gadget selection menu, click on any gadget that is not available (for example, Santa Ana, Bilbao, etc). In the next screen that will open, the "Restore" button will be available at the top left. Best regards, KORG App Team ### 4/5 — No full sized keyboard button? Please turn into an auV3 *2024-12-26* Why did you guys get rid of the most important feature of this app? Which is the full sized keyboard button. The app is barely unusable with this feature, I can barely use the keyboard properly because of this. It would really mean a lot to me and others if you bring this feature back. Please turn this app into an auV3, we would appreciate it if you guys turn this into an auV3. **Developer response:** Hello. Thank you for your feedback. If you want to make bug reports or feature requests, please contact our support channel: https://support.korguser.net/hc/en-us/requests/new We are gradually adding AUv3 to our apps, but we do not have a defined schedule for it yet. Hopefully we can see the iMono/Poly as AUv3 in a near future. Thank you and best regards, KORG App Team ### 4/5 — it’s good *2024-07-21* I’ve made some great patches on here, I request for there to be a way to transfer patches from here to the desktop computer vst version **Developer response:** Hello. Thank you for your message. For bug reports and feature requests, please use our support channel: https://support.korguser.net/hc/en-us/requests/new We hope you enjoy the KORG Mono/Poly. Best regards, KORG App Team ### 4/5 — A good synth that could be great *2024-02-13* If it had the following features added: -The ability to store preset files on the device you’re using and store them on a flash drive. -Keyboard portamento to filter cutoff. -Double tap a knob to zero the parameter also a fine adjustment. -The ability to save the mod wheel position in the preset. -Scroll and lock keyboard to a key other than C at the beginning and end. -Put the octave switches on the left when using the large keyboard so the preset menu does not block them. -Key transpose for the arpeggiator. -An undo/redo feature. - A portamento on/off button. -Having the Arpeggio rate (MG 2) a mod destination. Add these to it and it will get five stars. Still, it’s a good little synth. **Developer response:** Hello, thank you for the message and feedback. We have compiled you suggestions and shared with the developer team. Regarding the "fine adjustment" of knobs, please note that you can use the "flick" gesture to perform small changes in the control values. Thank you for helping us improve our products and please enjoy the KORG iMono/Poly. Best regards, KORG App Team ### 4/5 — AUv3 Please! Otherwise great *2024-01-14* It’s a wonderful synth. Great tones. Good UI. I just wish they would update it with AUv3. I’ve had it for years but I’ve barely touched it lately because with my workflow all my synths are hosted within my other apps (Logic, Loopy, Drambo, etc). I can’t be bothered with IIA anymore it’s just not stable enough. Please Korg! Add AUv3 support and it’s a 5 star app. ### 2/5 — NO AUV3 = 2 stars *2024-01-12, version 1.2.6* Come on guys. This is not a professional decision. Amazing sound though. ### 4/5 — Great synth but no AU compatibility. *2023-12-26, version 1.2.6* Why create a great synth app, then handcuff it without the ability to use it in AUM?? Makes absolutely no sense to me. ### 4/5 — Decent but not as good as the real thing *2023-08-15* Still the best overall synth you can buy for Gadget, but having used the original hardware this summer….the sound just isn’t as good as the original, especially for basses. Korg should revisit this legendary synth with more attention to detail. Maybe it’s just the filter that needs updating (with a zero delay feedbcak filter). ### 4/5 — Prima Sound - gute Umsetzung *2023-06-25* Es fehlt AU, deshalb keine 5 Sterne. Zum Glück ist kein Trommler im Programm, das macht die Sache übersichtlicher. Sound und Programmierung ist sehr gut. Das Layout so klar, dass es für „Einführung in analoge Synthese“ prädestiniert ist MPE Unterstützung fehlt mir auch, dafür ziehe ich keinen Stern ab, aber fehlende AU Unterstützung ist schon bitter. Alle meine KORG Apps kann ich mich Logic iPad nicht nutzen. Ist doch kein Hexenwerk, auf dem Mac geht es ja auch. ### 4/5 — Great sounding synth, Audio Unit needed *2022-12-23, version 1.2.6* This is a great sounding synth. Audio Unit capability is need to take it into the future. ### 4/5 — Disappointed by lack of AUv3 support *2022-11-27* Korg’s iMono/Poly is the virtual synth I’m enjoying the most at the moment, but the lack of AUv3 support keeps me from using it. With Moog’s Model D app, I can have three tracks in my DAW each with its own Model D instance and each Model D instance using a different patch. But with iMono/Poly, I can only have one instance of it. So, for composition, I have to use Model D instead and forego the features of iMono/Poly. Not to mention that not all DAWs work with IAA, and the ones that do still work better with AUv3. I’d even be happy to pay again for a separate AUv3 version of iMono/Poly. ### 4/5 — Good but where is latch button? *2022-11-12* Lovely sounds but when using in Korg gadget I can’t find a latch button for the ARP patches. Am I just being dumb or do these things only work in standalone mode? Help appreciated. ## Most critical reviews (10 lowest-rated) ### 1/5 — 4年アップデートなし *2026-07-26* 他の使うからいいや ### 1/5 — No AUv3- useless *2025-08-06* No AUv3- useless ### 1/5 — Useless in the modern AUv3 world *2024-08-05* I bought this on the assumption (so entirely my fault) that it would support AUv3, in the same way that iM1 does. It does not. More fool me. This was a complete waste of money. It sounds great standalone, but I want to use it with other synths and effects and I’m not working with inter-app audio as it’s too unstable. **Developer response:** Hello. Thank you for your message. We are sharing your feedback about AUv3 with the developer team, for consideration. Best regards, KORG App Team ### 1/5 — No AUv3 Support *2023-09-04, version 1.2.6* Korg, it’s 2023! Update your apps to support AUv3 hosts otherwise they’re useless. ### 1/5 — Auv3 ? *2023-07-21* Pas utilisable avec Logic et grosse galère en inter app audio C’est pareil pour toutes les applications Korg ### 1/5 — NO AUv3 SUPPORT *2023-05-19* Come on Korg this is ridiculous!!!! It’s been how many years now? I deleted Gadget because this. Gadget was born on iOS yet you give the flexibility to desktop only. I never bought the desktop version because of your shady business dealings on iOS. I spent over $200 on your iOS products. To access gadgets on desktop, to put in your personal daw, is $200. Over it. ### 1/5 — No auv3 *2023-03-19* 🤦‍♂️ ### 1/5 — Sounds good but scale selection is broken *2021-06-17, version 1.2.5* Can’t go back to a standard keyboard after using a scale. User scale does nothing. Manual says nothing. Why would you not have an option to go back to having all of the keys? ### 1/5 — A downgrade by removing the random feature *2019-12-27* How bizarre is this, they have downgraded the app for no apparent reason and removed the most useful feature. Behringer FTW! ### 1/5 — Does not work with nanokey studio Bluetooth. *2019-11-28* iOS 13 iMono/Poly can’t connect to Kong’s nanokey studio via Bluetooth. Widely known issue for few months now, korg are unable to fix this for quite some time **Developer response:** Hi, we finally released new firmwares for our controllers to fix this issue. Please download and try again? https://www.korg.com/news/2019/112903/ ## Most praised reviews (10 highest-rated) ### 5/5 — Cool! *2026-06-05, version 1.2.6* Cool!! Plz Adaptive Cubasis 3 auv3. Auv3 plz!!! ### 5/5 — Cool! *2026-04-13, version 1.2.6* Cool!! Plz Adaptive Cubasis 3 auv3. ### 5/5 — Beautiful *2025-11-19* Great app I have them all now wish more showed up in iMPC that would really put y’all on top! Tyty ### 5/5 — Great sounding synth, needs AUv3 support *2025-06-28, version 1.2.6* This is a great sounding synth. Audio Unit AUv3 capability is needed to take it into the future. ### 5/5 — Monopoly skin? *2020-05-20* Oh ... mono poly ... i geddit .. Sounds good, bit different to Polysix, which i know better having had one.. ... Why "dirtyfy" the buttons/panel, etc? Thought my screen was dirty at first.. "Immaculate" option please... ### 5/5 — Korg is wonderful! *2020-02-03* Big hug! ### 5/5 — Please fit it to the larger iPhone screens *2020-02-01* Still people with large phones have so much wasted real estate. ### 5/5 — Great synth *2019-12-04* Plz make it AUv3 like electribe wave ### 5/5 — KORGらしくて良いですね *2019-11-19* これはKORGのシンセサイザーそのものですね もうもはや、スマホのシンセなのか、シンセのスマホなのか、どっちだったっけ？だっけけけっけれれれーーダッケッッしゅっしゅシャ~ って感じです。発振するモジュールの組み合わせによって理論的に♾通りの音をつくれる。とくにモノの音をポリフォニーで出せるので基礎工学の研究状態のカオスみたいになるよ。完璧だと思います ### 5/5 — Auv3 please!! *2019-10-23* it would be fantastic to have this one in auv3 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
