Intuitive, fun, and impressive!

Elastic FX is a fabulous effects app, with a beautiful design and top-notch sound-mangling quality! If you’ve used Elastic Drums, you’ll be equally impressed by the musicality and usability of this app. I’ve already tried feeding audio into it from Ableton Live by way of Studiomux, and it works like a charm. And I’ve used it inside of Modstep to process sound from other iOS apps. This app will surely become a go-to component of my creative workflow. And as a teacher of electronic music at the high school level, where we use both Ableton and iPads, I’m excited for students to start putting this through its paces. Highly recommended!!!

yet another app getting me closer to completely ditching laptop for iPad. I always especially liked how the effects section of elastic drums was implemented, so I was stoked to be able to throw it plus so much more into any signal chain. Only thing I’ve noticed that isn’t that big of a deal but took a second to get used to, when switching between effects I have to press then scroll before release or else the effect turns off. Maybe some way of doing either or would be cool, but it’s such a minor grievance I wouldn’t let it stop me from giving this app 5 star rating. Thanks for the hard work!



Better than some virsyn type effects
