User reviews

Positive early impressions

My only issue is the randomisations go a bit extreme. The jump in complexity from medium to high is a bit much. Would love a more gradual approach or something in between these

Cannot see midi out channels in AUM

Why doesn’t Heliums midi channels appear in AUM /
?

Crash Crash Crash

Nonstop crashes with this app. I am using it in AUM on an A16 iPAD with just 2 tracks of sequenced midi, each on a different port. AUM is running at ~30% CPU and it’s just crash after crash after crash. Absolutely unusable in a live setting. So disappointing. I will be purchasing Atom 2.

Fantastic App

It’s amazing to see the developer continuing to maintain and advance Helium 4 years on. 4Pockets apps basically require you to watch the tutorial vids, as the interfaces are often overstuffed with useful things. But once you figure out Helium, it’s incredibly powerful. (And I find it sad to see a 1-star review because the app is missing a niche feature… Helium provides tremendous value for its minuscule price.)
