AUM update – Jonatan Liljedahl’s brilliant iOS audio mixer app gets some tweaks

Download from iTunes App StoreAUM logo 1There are some developers that qualify for almost universal hero worship amongst the iOS music making community and Jonatan Liljedahl is one of those. So, whether it is the ubiquitous utility app AudioShare, the truly inspiring (and sometimes mind bending) electronic rhythm/groove app Sector, or the minimalist audio effects of the AUFX series, Jonatan creates brilliant apps that almost any iOS musician would want to own.

And, with perhaps his flagship iOS music app – AUM – he did it again; AUM is a brilliant piece of software with with sophisticated audio mixer features allowing you to combine multiple apps into a music making workflow and support for Audiobus, IAA and AU apps. Until the appearance of Audiobus 3 (which added basic audio mixing and sophisticated MIDI routing options to that platform), AUM was the stand-out ‘audio mixer in an app’ for iOS. It might not adopt the conventional graphics of a ‘real hardware’ look, but it certainly offers the audio routing typical of a decent hardware mixer.

AUM gets an update – v.1.2 has arrived on the App Store :-)

AUM first appeared in February 2016. Since than, there have only been a few updates but I think that simply reflects how good it was to start with (not much missing) and how solid the coding is (few bugs to fix). However, today sees the first new update since May as v.1.2.1 has appeared on the App Store.

There are some fixes that address various details, but there are also new features and refinements to accommodate changes elsewhere in the iOS music technology universe. In terms of fixes, examples include a fix when restoring MIDI mapping to some AU plugins and tweaks to solve very rare MIDI/IAA problems. The Audiobus SDK has also been updated.

New features include the option for sending MIDI Clock when syncing external hardware, a new Bluetooth LE MIDI option in the Settings menu, some tweaks to the session notes system to make it clearer for the users when notes have been added and refinements to the recording system to make it less likely that the recording process will miss anything..

AUM offers audio busses allowing you to replicate the kinds of audio routing associated with sophisticated hardware audio mixers.

Anyway, at UK£18.99/US$19.99, this is not the cheapest iOS utility app you might ever buy for your music workflow but it is certainly one of the most useful and powerful. If you like to combine lots of apps together, rather like Audiobus, AUM is a very powerful tool. The app requires iOS9.0 or later, is a 6.3MB download and is universal.

If you want to find out more, then read the original full AUM review here (and the AB3 review which compares AB3 and AUM in terms of functionality), check out the video below and then hit the download button to read more on the App Store. And while you are there, check out Sector – Jonatan’s equally brilliant loop mangler/rhythmic magic app – as it’s an often overlooked masterpiece (and here’s hoping it also has an update coming soon).

    1. An essential App and I wish there was a computer based version so that I can use my more advanced AU/VST for mixing my hardware in a live stage environment. I don’t need most of the usual DAW stuff because I use machines but I do have AU/VST that are not available on the iPad that I prefer to use.

      So maybe a Mac OSX version?…please? ;-)

    2. Hi, Holotropik , there is a fantastic program for Win/OSX called LiveProfessor by audiostrom. There are free, and paying versions, in 32 and 64 bit. I have used AUM and LiveProfesser extensively. They are similar in some ways, but LiveProsessor is designed with live stage work specifically in mind. I have also used LP as a studio tool. It is fully AU/VST compatible with full routing etc………give it a spin, i think you will be pleasantly surprised! cheers for now…….Mark…..

    3. Hi,Holotropik ,I have just been to the audiostrom site, and the model has changed slightly , as it has been updated to version 2, with a paying version which is 69e with a 100 day free trial. If you scroll down their download page, version 1 is still available for download, and that has a fully working entirely free version, although if you can afford it 69e is a bit of a steal for the latest version…….cheers…mark….

    4. Apologies……both versions have a 100 day free trial…….no free versions anymore……the model must have changed at some point………69e is still a very reasonable price for the usefulness of this software for live/studio work……cheers…….
