All the effects sound over the top

I’m not sure if I’m doing something wrong but all the effects sound way too extreme. I just want a gentle reverb and everything is crazy! Would love it if the presets were toned down a lot more

Such a magical reverb!

Pure space✨

FAC Alteza has been part of my recent sound work — I love how it opens up space in such a deep and emotional way. The shimmer feels organic, never artificial, and the interface is so intuitive that it invites instant creativity. Perfect for creating wide, dreamlike soundscapes, even for beginners.

Perfect on iPhone

A big and great thanks to the developer, because great sound is one thing but usage on the iPhone another story. The whole package of apps have a great sound and the AUM user interface changes if you are on iPad or iPhone. Perfect usability on iPhone!
