Loading AUv3s quits the app but Ive played around with what is included and I would go totally insane if this could become a regular tool in my toolbox. In love with many grooveboxes like Drambo but to have touch optimized albeton like performance scene launcher would be a dream. (i know LK exists but can’t get into that one.) If only loading auv3 was fixed i would already esctatic. ### 3/5 — Instrument laden = Absturz *2022-01-30, version 1.3.2* Vielversprechende App, leider stützt sie aber zu oft ab. Die App hätte das Potenzial die Zentrale Steuerzentrale in einem Liveset zu sein und hier sogar dank Touchbedienung Platzhirsche wie Ableton verdrängen zu können, wäre sie nur stabil/zuverlässig genug für den Livebetrieb. Aktuell durch Abstürze unbrauchbar, werden die allerdings gefixt hat die App 5 Sterne mehr als verdient. ### 2/5 — Работает некорректно ! *2021-07-02, version 1.3.2* Не загружает AU, AUv3, !!! Выкидывает с приложения! iPad Pro 16.4!!! Исправьте. ### 4/5 — Wow *2021-03-02, version 1.3.2* Can’t believe I missed this app when it came out. This thing is hugely deep and the level of details that the dev put into it is simply mind blowing! Hopefully they consider supporting it again, there’s a whole new wave of iOS musicians now vs 3 years ago. This thing is an epic work of art ### 3/5 — I’m so sad about MODSTEP😢😫😭 *2021-02-03, version 1.3.2* I LOVE Modstep. I’ve spent 2 years learning it and figuring out work arounds cause it seems it’s been abandoned. I still stood by it cause it’s just so good at sequencing, program changes, notes, ccs. Awesome for external gear and worked with AudioBus for routing to AUM. But now I can’t even load it! Please update so it can operate in os 14! All my projects are dead now... 😰😩 Even if it’s not auv3 it’s still the best sequencer imho. ### 3/5 — auv3 no funciona *2021-01-20, version 1.3.2* cuando intentas cargar un auv3 se cierra el programa, tengo un iPad Pro ### 1/5 — App is not working properly with ios14 *2020-12-20, version 1.3.2* I bought this app but when I add an external midi instrument it doesn’t sound. When I try to add an AU instrument it hangs. I’d appreciate you update this applicarion. ### 1/5 — Unusable with iOS 14 *2020-10-25, version 1.3.2* Not possible to load auv3, modstep will crash instantly Also frequent crashes on startup Under iOS 13 worked everything and never crashed once. Last update was 3 years ago... Hope the devs check in to it or I wasted money.. ### 3/5 — So sad ... *2020-09-26, version 1.3.2* ... that this app has died. I had barely got used to using it when the bugs started. 2 years later and all I get is a black screen when I try to load it. It was a great app and could have developed into something really special but I guess someone fell out with someone else or got a better job offer or something! Damn shame to see an app like this get shelved though. Puts me off trying their other apps tbh. EDIT. A FEW MONTHS LATER AND I TRIED AGAIN, THINKING A FRESH START MIGHT BLOW SOME COBWEBS OFF. BUT NO, THE BLACK SCREEN DISAPPEARS AFTER ABOUT 15 SECONDS, BUT AS SOON AS YOU LOAD AN AUDIO UNIT, IT CRASHES. IT’S SCANDALOUS THAT THIS IS STILL FOR SALE AT £9.99. SERIOUSLY, DO NOT BUY THIS APP! ### 3/5 — Was good before the iOS updates *2020-06-08, version 1.3.2* Running on the new 2020 iPad Pro 12.9 and inter app audio seems to be broke. , can’t get any sound at all, was working fine on my old iPad on iOS 12 ### 1/5 — Don’t work! *2020-05-12, version 1.3.2* In iPad Pro no load instrument IAA and AU. Why? Also Sampler don’t work so good ### 1/5 — Useless *2020-04-25, version 1.3.2* Crashes every single time I try and load an IAA instrument. I so want this app to work! But...... ### 1/5 — Tried to be nice but looks to be abandonware $20 down the drain *2020-02-07, version 1.3.2* I for one wouldn’t mind paying for an upgrade for any additional improvements (i.e. auv3) and stability to keep you all going. This was is a great app and I have had some great results with my outboard gear and love the internal sound capabilities as well. Thanks for the app- edit below BUYER BEWARE- looks to be abandoned ### 1/5 — Sehr schade... *2019-12-18, version 1.3.2* Eine wirklich tolle App. Genau das, was ich immer gesucht habe. Ist aber leider unbrauchbar, da ständig Abstürze. Ich hab vieles versucht, leider ohne großen Erfolg. Wird aber wohl nicht mehr weiter entwickelt. Schade.... ## Most critical reviews (10 lowest-rated) ### 1/5 — Achtung ⚠️ *2024-09-15, version 1.3.2* App wurde 7 Jahre (2024) nicht verbessert. Es funktioniert fast nichts mehr. Ständige Abstürze. Webseite ist auch down. Müsste eigentlich aus dem Store fliegen. Unglaublich! Apps kann man übrigens rückerstatten lassen. Einfach Rückerstattung und Apple googeln. ### 1/5 — A éviter ! *2023-10-31, version 1.3.2* L’appli n’a jamais été parfaitement stable, mais elle est maintenant totalement inutilisable sur les ipad "récents" (< 2020) faute de suivi. Comment cette application peut elle être encore en vente ? ### 1/5 — Does not work anymore *2023-09-01, version 1.3.2* 😭😭😭 ### 1/5 — Turned Garbage *2023-04-13, version 1.3.2* After an update The app won’t stop clicking. Metronome is off. All tracks are stopped. Still clicking like crazy. Impossible to use. Seems the Devs broke it long time ago and ran away. ### 1/5 — I think we can call this abandon ware now *2022-10-30, version 1.3.2* I was really excited about this app when it came although it was alway pretty wonky and I often spent more time troubleshooting and trying figure out how to use it than get songs done. It’s always been full of bugs and I think it’s safe to say after 5 years and no updates it’s abandonware. The real question is why is this app still on the AppStore? Obviously the developer doesn’t care about ModStep and has moved on, so why sell an app you’ve given up on? ### 1/5 — 使いにくいです *2022-04-19, version 1.3.2* genomeが使い易いです。 ### 1/5 — Une arnaque *2022-03-18, version 1.3.2* A éviter à tout pris , ne fonctionne avec aucun auv3 , passe son temps à crascher , sincèrement comment peut on vendre une app avec autant de problèmes, je fonctionne sur un iPad Pro avec le dernier iOS ### 1/5 — Je me suis fait avoir *2022-02-11, version 1.3.2* Comment est-possible que cette app soit encore proposée à achat en 2022? Une honte!!! C’est du vol organisé! Sous iOS 15 impossible d’utiliser les AUv3. Quel intérêt du coup?? ### 1/5 — Don't be fooled: do not buy! *2021-03-14, version 1.3.2* While it is a nice app in theory, it annoys me about every time I try to use it. Even years after it's release, it is still full of of bugs and I do not believe any fixes are coming. Some examples: The other day, it took 5 or 6 times of restarting it before it actually loaded the project. I think it was the first time it took so many tries, but loading projects only after a few tries is a very regular occurrence. When you select a specific MIDI-in device on a track, it still gets MIDI from all everywhere and you have to mute track you do not want played by the incoming MIDI. Even if nothing is armed and when the channel is a different one! When you "save as", the currently selected track gets renamed to that name, too. That's especially annoying when you are using track names to reference which external sound the track should control. And these are just what I encountered on my last tries of using the software. I bought it pretty much as soon as it came out. At 20$ it was the most expensive app on my iPad, and never got to actually use it. I did not want to give a bad review because, as I wrote at the top, it is a nice app in theory, but I feel tricked and I do not believe that it will ever get in a usable state for me because the creators do not seem to care about the bugs and the bad reviews they deservedly get. Edit: Now trying to load AU synths crashes modstep and IAA synths do not produce any sound! ### 1/5 — 動作しない *2021-02-12, version 1.3.2* アプリが落ちて動作しない。 最初にインストルメントを選択する時点で落ちる。AUも選択した時点で落ちる。使えない。すぐに返金の手続きしました。 iPad７　iPadOSは最新です。 ## Most praised reviews (10 highest-rated) ### 5/5 — Ganzes Midi Studio *2021-03-25, version 1.3.2* Steuert mittlerweile meine 8 hardware synthesizer ganz alleine. Dabei spiele ich alle auf einmal und lese sogar automatisierungs CC in verschiedenen Spuren. Bisher nicht einmal abgestürzt. Top App! ### 5/5 — 2020-Update? *2020-07-27, version 1.3.2* Would love to see an update to expand features, depth of audio editing features, performance screens, and overall house keeping. Let the king retake the thrown for all who don’t know! ### 5/5 — Waoooo *2020-06-09, version 1.3.2* One of the best . Finally I work flow I can relate ,is almost like a ableton live type vibe for iOS .I hope they keep updating it .Worth the money .Thanks ### 5/5 — ニッチな存在 *2020-02-14, version 1.3.2* とにかく重宝しています。メインというよりフォロー的な使い方が、良いと思います。elektronやopz、また、ガジェットや、 モジュラーなどとも相性が良いと思います。 私は、コピーフレーズの楽器練習時にも重宝してます。 かなーーり気に入っています！ ### 5/5 — Au top ! *2019-10-20, version 1.3.2* Excellent séquenceur, précis et efficace, le tout à un prix raisonnable. Modstep reste pour moi l’un des meilleurs séquenceurs sur iPad 👍 ### 5/5 — This is my main live sequencer app! *2019-07-20, version 1.3.2* Please don’t forget this app, it’s amazing and it has a lot of potential. It just needs some stability and intuitive improvements. ### 5/5 — Best of the best !!! *2019-05-01, version 1.3.2* It is super convenient, clever, ingenious, great automation of modulations, wonderful, convenient sequencer and much more! Developers you are magicians and think very well! Please do not forget this great app, at least to update the upcoming IOS. Thank you so much for your ideas, I wish you new creative, ingenious solutions !!! ### 5/5 — Perfekt für meine Volcas *2019-04-08, version 1.3.2* Ich benutze Modstep für meine Volca Beats, Bass und FM, dazu ein Arturia Keystep. Nach längerer Einarbeitung und Anschauen vieler YouTube-Tutorials macht Modstep unglaublich viel Spaß. Abstürze hatte ich noch keine, alles läuft stabil. Daumen hoch! ### 5/5 — Brilliant *2018-10-08, version 1.3.2* Brilliant app! ### 5/5 — Love it *2018-10-02, version 1.3.2* One of the deepest, most creative, most fun and interesting music production apps out there. Love it. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
