Is there any hope of getting the triton auv3 ? ### 3/5 — Heavy with DLC packs *2026-05-26, version 5.1.1* Not a fan of the add on packs, to get them all it would be hundreds. Still, the base pianos you get here sound nice ### 2/5 — Excellent Product Overall *2026-04-29, version 5.1.1* I couldn’t give it any more stars, as I am really miffed at KORG. I purchase the add-ons, paying a lot of money for the in-app purchases, and KORG arbitrarily deletes them from the available page. Fine, then refund us,, don’t just keep the money and discontinue.. not cool ### 2/5 — current version not holding purchases *2026-02-04, version 5.0.10* feb 4/26 since the most recent update, Module Pro does not retain my purchases and i have to restore them every. time. help! i've deleted and reinstalled the app, it still happens...... help! ### 3/5 — Important glitch to fix *2026-01-30, version 5.0.10* I want to give it four stars but for someone who uses it on stage there is a glitch that can wreck your sounds until you restart the app. Namely if you have purchased additional sound packs sometimes when you start up the additional sound packs will not appear and any custom set list entries you have built that use those additional sound packs will sound very weird due to the missing sounds, until you restart Kong module pro ### 3/5 — Latest Update Purchases show installed but not in Module presets… *2025-12-15, version 5.0.10* As above. Update: I installed the free version of Module and did a restore purchases which restored them and restore the purchases for Module Pro the uninstalled the free version of Module and everything was still there. This is a work around but the issue still persists in Module Pro. One star added to what is otherwise a fantastic app. Previous review as of 15 December 2025. Module has seemed more unstable recently with Oasys piano install constantly disappearing, now all my purchases show as installed but not in the preset browser. Reinstalled and deleted content but problems persists. ### 4/5 — DS-1Hでのハーフペダル対応してほしい *2025-12-02* 無料版からProにアップグレードし、Ivoryも2種類とも購入いたしましたが、America Dの方がオススメです。 要望ですが、D1にDS-1Hをつなぎ、スタンドアローンでの使用時はハーフペダルが対応するのですが、KORG Module(iPad)を経由した時はハーフペダルが対応しませんので対応をお願いしたいです。 iPadが調子悪くなったので初期化し、KorgModuleを再インストールし直しましたが、購入したIvoryなどが復元できません。(レシートを読み取れませんでした)のメッセージ。 **Developer response:** レビューをお寄せいただきありがとうございます。 ご要望については、恐れ入りますが以下のサポートチャンネルよりご連絡いただけますでしょうか？ https://support.korguser.net/hc/en-us/requests/new チーム一同、ご連絡をお待ちしております。 よろしくお願いいたします。 コルグアプリチーム ### 3/5 — Great Korg piano sound, but won’ install on Apple Silicon Macs *2025-11-07, version 5.0.6* Several other instrument synthesizers that were originally designed for iPad and iPhone now run on Apple Silicon Macs, greatly simplifying MIDI music live performances and MIDI music performance recording. This paid Pro version of Korg Module ought to be just as versatile to run on MacOS as our more complex symphonic instrument synths and pipe organ synths. ### 4/5 — Suggestion *2025-10-14, version 5.0.5* Need to have the Split and Layer function working together at the same time ### 4/5 — Modular pro is great, loving it, however…. *2025-10-11, version 5.0.5* I do love the modular pro app, I did think it was a bit cheeky letting you buy the app, and then you need the extension, felt like paying for it twice, naughty Devs. However, it is great. I bought a few Sound packs for my MIDI Keyboard. My main gripe is the quality of the sounds on the demo are not quite what I experience when playing with my MIDI Keyboard, also my sustain pedal does not work properly with the app, it simply holds the note forever at what ever tone it was at when the pedal is pressed, this does spoil it quite a bit…. like my normal keyboard the sustain pedal fades off gently, this does not happen through the app. I do love the brass band section. Also just thought I would mention, I’m keep having to re-download the sound packs on my iPad, when I open the app, it’s not remembering I already have them. Could that be looked into please. Please fix sustain pedal function and Download Remembering Thanks ### 4/5 — set listの改善について *2025-10-08* 曲ごとにトランスポーズのキー設定が保存できて、リスト表にトランスポーズ値が表示されないだろうか。そうなればAppleのMainstage3から移行できてMacBookを運ばなくて済むのにな。ぜひ改良してほしい。そしたら⭐︎五つです。 **Developer response:** レビューありがとうございます。 お手数ですが、詳細についてはサポート窓口までご連絡いただけますでしょうか。 https://support.korguser.net/hc/en-us/requests/new どうぞよろしくお願いいたします。 コルグアプリチーム ### 2/5 — Probleme beim Restore der gekauften In App Instrumente *2025-08-27* Ich habe das Modul neu geladen und konnte nicht mehr auf einige restore Instrumente zugreifen. Erst nach mehrmaliger Löschung und Neuinstallation der App klappte es irgendwann. Ich musste das Oasys Modul 2 mal kaufen. Habe jetzt an Apple eine Rückforderung gestellt wegen doppeltem Kauf. Das ist ein Problem von Korg, der Support ist bis Ende des Monats nicht erreichbar. Das ist auch unmöglich. Korg bitte kümmert euch um dieses Problem, das wurde im Netz schon mehrfach bemängelt und es passiert nichts. **Developer response:** Hello. We have fixed this problem is previous updates, so we are giving you a feedback here. If you ever face any problems, please report to our dedicated support channel: https://support.korguser.net/hc/en-us/requests/new Our team will be glad to hear from you. Best regards, KORG App Team ### 2/5 — still restoring! *2025-08-12, version 5.0.4* well the app doesn't ask me to RESTORE everytime i open it, but now i HAVE to restore because my purchases don't load. so it's the same problem, just different! ### 4/5 — バックグラウンドでの動作 *2025-05-14* 他のアプリが開いても演奏できると良いと思います **Developer response:** レビューありがとうございます。 お手数ですが、サポートチャンネルまでご連絡いただけますでしょうか。 https://support.korguser.net/hc/en-us/requests/new チーム一同、ご連絡をお待ちしております。 よろしくお願いいたします。 コルグアプリチーム ### 4/5 — Great but........ *2025-04-12, version 5.0.0* Very high quality sounds. It would be vastly more useful if it was multitimbral and have split/ layer functionality. Update: Korg informed me that there is split and layer functionality. There absolutely is, however you only have two parts. I was thinking more in terms of like how lots of hardware romplers have a combi mode where you have anywhere from 8-16 multitimbral zones. This is an especially important feature for keyboardists in cover bands or where we need to cover a variety of different parts at the same time. For example, a single patch containing 5 zones where zone 1 is an EP layered with a string pad, zone 2 is a synth brass patch, zone 3 is a synth lead, zone 4 is a marimba an zone 5 is an organ. This kind of functionality would be killer. ## Most critical reviews (10 lowest-rated) ### 1/5 — 音が狂ってます。 *2026-04-02* アップデートした途端、ミの音、シの音が半音下がったり、チューニングがズレた状態になってます。使い物にならないので、原因を探って直してください。 あと、サポートリンクの件ですが、こちらでリンクを貼ってくださるのですが、わざわざコピペをしなければ、リンクへ飛びません。しかも言語が日本語では無いのでわかりづらいです。 **Developer response:** レビューありがとうございます。 いただいたご意見は開発チームと共有させていただきます。 ご不明な点がございましたら、サポートチャンネルまでご連絡ください。 https://support.korguser.net/hc/en-us/requests/new よろしくお願いいたします。 コルグアプリチーム ### 1/5 — NO note names *2026-02-27, version 5.0.11* doesn’t even tell you what note you’re playing. Absolutely worthless. Notes are not labeled ie C2, E4 ### 1/5 — Worst app ever *2025-12-03, version 5.0.9* Worst app ever if you buy it they do not refund it as they know it is bad app and you want to return it. Be careful DO NOT BUY THIS APP it is the worst ever and very bad support. ### 1/5 — 80’s eléctrica piano desaparece *2025-10-11, version 5.0.5* Tengo que volverlo a descargar cada vez que lo uso ### 1/5 — Double charged and won’t refund *2025-07-02, version 5.0.1* There are two version the pro and the free. Both look almost identical and it was just to easy to get them mixed up and end up buying IAPs in both apps. Compound that by the fact there no way to deinstall the plugins that are not needed for a project in order to save memory ……but instead have to delete it with all the confusion that ensues across both apps…. I’m out of pocket by about 80 quid. No worries I thought apple will see it’s duplicated and refund. But no. Requests for refunds denied… and 3 apple support reps and 2 hrs of hassle later they still have my money. Complete scam if they take double the money for the same apps! ### 1/5 — Bluetoothの遅延がひどすぎる *2025-05-05* microKEY AirをiPadProにBluetooth接続してるが、発音が鍵盤のタッチから平気で1秒以上も遅延する。使い物にならないでしょ。何のための純正アプリだよ。 **Developer response:** レビューをお寄せいただきありがとうございます。 Bluetooth MIDIは僅かながらの遅延が発生してしまいますが、1秒以上の遅延となりますとレイテンシーの設定が適切になされていない可能性がございます。KORG Module ProのSettingsからオーディオレイテンシーの設定を行なってください。 お手数をおかけいたしますが、何卒よろしくお願い申し上げます。 コルグアプリチーム ### 1/5 — Can't Update *2024-12-17, version 4.7.1* Module Pro links to defunct Apple account and I can't change it to active account or repurchase it on active account ### 1/5 — Module Pro Now Crashing *2024-09-30, version 4.6.8* After using Module Pro in my professional keyboard rig for over 4 years, the program has proven itself unreliable due to regular crashing. The program will freeze on my M1 iPad Pro forcing me to close the program and reopen it, sometimes in the middle of a gig. There is also a frustrating problem with it not remembering set list edits, even though I constantly save my set lists, sometimes newly added songs disappear. I am looking to drop Module for a more stable app. After being promised a two months ago that an update addressing these serious problems was “imminent”, the program is still losing songs and crashing during gigs. I suggest that you look elsewhere. ### 1/5 — Sudden major problem *2024-06-10, version 4.6.7* I use Korg Module Pro in the AUM app. Suddenly today, when I open a saved project with Korg Module Pro in one or more tracks, if I change the voice it is playing, the track with Korg Module Pro instantly crashes. This failure is happening 100% of the time. ### 1/5 — New Packs Not Showing Up in Gadget 2 *2023-06-29, version 4.5.8* Korg Module is supposed to integrate with gadget 2. I bought the packs that are on sale today. None of them are showing in gadget 2, even w refreshes and restores. I went thru every gadget associated with Module Pro, and there is nothing of the new sounds showing up in gadget 2. This plugin no longer works as advertised with gadget 2 ## Most praised reviews (10 highest-rated) ### 5/5 — Muy bueno *2026-07-02, version 5.1.4* Espero que pronto puedan agregar otros piano como el 01W y el n364 ### 5/5 — Update/upgrade *2026-06-09, version 5.1.3* Hi Korg I really love the pure guitar magic but can you guys give us the pure guitar magic sounds with no effects just the clean version of each guitar in korg modules and in Santa Ana where we can put our own effects and give us possibilities in korg modules to mixe 6 to 8 different sound together and level them too however we want and thank you korg modules team keep up the good works guys. ### 5/5 — Update/upgrade *2026-04-13, version 5.1.0* Hi Korg I really love the pure guitar magic but can you guys give us the pure guitar magic sounds with no effects just the clean version of each guitar in korg modules and in Santa Ana where we can put our own effects and give us possibilities in korg modules to mixe 6 to 8 different sound together and level them too however we want and thank you korg modules team keep up the good works guys. ### 5/5 — Worth the cent *2025-11-22, version 5.0.6* I don’t normally say this, but this is one of the few musical app that made me feel something. ### 5/5 — 为什么换了iPad显示要在购买 *2025-11-18* 换了设备同样的苹果账号为什么显示了价格需要在购买，哪位出来给解释一下。。。。。 ### 5/5 — Great App! *2025-09-26, version 5.0.4* I am very impressed! After my Nautilus missed a Delta flight this week, I decided to duplicate our entire show using Module with AUM for splits. The sound quality was easily on par with the Nautilus (of course, the Nautilus is far deeper). I can't wait for the day Korg expands the app's split/layer capabilities! ### 5/5 — 最高の音源 *2025-08-31* こんな凄すぎる音源がこんな価格で良いの？っていうくらいです。 ### 5/5 — restore restore restore *2025-07-21, version 5.0.3* everytime i open the app now it asks me to restore my purchases...and then i do...and then next time it asks me again...and again! helP! ### 5/5 — Excelente Aplicativo, melhor módulo portátil! *2025-07-10* Senti a falta de mais camadas/layers, pois o app limita somente a duas por vez. Não encontrei a função de mapear o midi cc em meu controlador para trocar/visualizar os layers e alterar entre os timbres direto na interface principal. **Developer response:** Olá.

Atenciosamente, KORG App Team ### 5/5 — Hi *2025-04-05* Hey friends, I'm Brazilian. I really liked the app, but I want to ask you for an update. Whenever we change a parameter of the tone, we can't return to the original value of the knob by double-clicking on it. So we end up having to open the app or the tone again to return to the factory settings. If you could make it so that you can return to the original value with just two taps on the button, it would make our lives a lot easier, lol. Think about it later, in short, it's just a faster way to reset something that was changed and return to where it was pre-set. Cheers! **Developer response:** Hello. Thank you for contacting us! We appreciate your feedback and we will share it with the developer team. Hopefully we can see a double tap implemented in the future.
