Oh My Gosh❣️😯👍


I've had Refraktions for a week (or two) but to be honest, after a few swipes of the screen and my socks didn't catch on fire (hubris, shear hubris on my part) I forgot about it..until I was cleaning up and moving newer apps to folders and I looked at Refraktions a little closer. Ohhhhhh Myyy Goshhhh❣️❣️ I mean I'm not sure what I'm doing with it yet but I see the potential now. Right now, while I dictate this, I'm listening to LayR being controlled by Refraktions. I'm using a saved LayR Performance with five instruments (and collectively six synthesizers) with some mild tweaking and 'performing' via Refraktions. I saved the developer's online user guide to a thirty-three page PDF also shows that there is much more to Refraktions than initially meets the ear. 😎🙏

Effective and stylish generative sequencer


Similar to a better implemented version of the Google Magenta AI Duet web app but reimagined as a multitrack midi sequencer. The (very cool looking) interface makes it hard to get specific with note input, but luckily it's scale locked so no real issues. The most important thing is the satisfying and quite musical response engine.
One thing that I would suggest is that it respond/reproduce more in response sustained notes. I felt there was a strong focus on pointillistic sequences but I could be wrong.

Thanks to the dev for this inspiring and innovative tool. A must buy if at all interested!

Absolutely AMAZING!!!


I stumbled upon this app and am so glad that I did! It's truly incredible, easy to use and works well with other apps. It was very easy to use other app sounds as the sound source and it is a BLAST! What I LOVE most is that it feels more like playing WITH someone. (And the sound quality is beautiful) Bravo to the developer! I give this app not just a thumbs up but full on jazz hands, beyond worth the small investment!
