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. ### 2/5 — Almost *2022-12-23, version 1.3.2* The App is amazing is a great sustitución for a letón live, the o ley problem that has is i can work with any extérnala apps ( crash ) When do you want load a Synth like Synthone or Aparillo is a shame clise the arquitectue of tris app is great .. ### 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? ### 2/5 — fantastic workflow but full of bugs *2022-09-11, version 1.3.2* It seems the app was not updated in a hot minute. 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. ### 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?? ## Frequently asked questions about modstep ### What is Modstep?
