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!!!

Great On It’s Own

Just got this on sale and ran into issues with audio hosting. On it’s own it is fun. Really fun. But when it is time for serious work especially in a live performance, not a choice effect when you want to get up and going. I had a loop on a synth going on in the input section and the EFX in the effects slot of AUM (and did this also with AB3). The only time I could hear a signal is when I was on the EFX app. Once I switched over to the host the volume would just go down. Once I switched to the Synth the volume would fade out. On AUM I tried both post and pre settings (thinking this needed some special set up. Anyhow, no dice.

Obviously this app has worked well for a lot of users. However I think other users have more time and patience than just bringing in a effects app into the host and expecting it to work with out other settings needed. Thats not how I perform. Effects for me just have to be “On It” when I perform live. EFX is just not one of those effects. Research before buying, how others set it up. It’s a great idea but needs more fixing to useable in a live situation.

This issue came up with iOS 12, but it should be fixed with the newest update! :)

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!
