Helium is a lightweight AUv3 MIDI sequencer plugin designed specifically for AUM. It supports up to 16 tracks of unlimited length with the ability to direct output to 16 channels on up to 16 MIDI output ports.

One of the great features is the ability to import and maintain libraries of MIDI clips using Helium's 'Media Bay'. These clips are freely available all over the internet and may contain individual chord sets, chord progressions or drum tracks. You can quickly build a song by dragging and dropping your MIDI clips from the media bay onto your timeline. You can also save your own clips directly to the media bay to create your own personal MIDI clips libraries. Long press on a clip to preview its contents using the currently selected MIDI device.

Helium now ships with a library of over 7000 MIDI clips, consisting of every chord and chord progression you could ever need.

Helium allows many different ways to import additional MIDI clip libraries. Simply drag and drop your ZIP collections directly to your PC/MAC web browser and they are automatically unpacked into the clips library folder. You can also drag and drop files between the Media Bay and the iOS Files app.

Helium supports a sync mode called 'Remote Looping'. This was something we recently introduced into our MultiTrack Recorder plugin and is very useful for breaking down the timeline into sections.  You can define up to 12 loops which can be used to specify the locations of say the intro, verse, chorus, and outro within your song, then trigger these loops seemlessly in sync with the host tempo. Once captured, these loops can then be triggered by incoming MIDI notes.

A new addition to Helium is the ability to piece together loops into songs, so you just concentrate on creating a single verse, chorus, bridge etc. and piece everything together without the headache of having to re-arrange your timeline.

Already a great app for midi recording IMO…

UPDATED: export feature does work. You have to look exported measures before exporting…. Maybe better to make default full exported file, with selected measures as an extra option…

Would really help to have easier to see highlight of selected notes.

Thanks for random feature, very helpful! Would be great to have independent melody and rhythm random as additional options, as additional variation options of original random generation….

Helium and AUM

I’m hearing a lot of great reviews about this app, but, I just don’t understand what is going on as far as the connection between this app and AUM, the app works just fine; for some reason, Helium is not even listed at all, I’ve even tried Audiobus and not in the database. I have an iPad 8G (iOS 14.4.1) I can’t even see its full potential because of this issue, hopefully it may be something I’m doing wrong. Any help would be gladly appreciated, thanks.

Hi there. You are most probably suffering the dreaded failed to install AUv3 bug in iOS. Try rebooting your iPad and it should show up fine. I cover this in the help manual under Installation Problems & Compatibility. If you are still having issues please let me know.
