AUM is the flexible audio mixer, recorder, and connection hub for your iPad, iPhone and iPod touch.
Connect hardware inputs and outputs, Audio Unit extensions, Inter-App Audio apps, Audiobus, soundfile players, built-in signal processing and filters, in any configuration you want.
Route anything to anywhere with mix-busses, effect sends, audiobus ports, and external multi-channel audio interfaces.
Play hosted synths and instruments using the built-in keyboard or external MIDI controllers, or sequence them with AU MIDI plugins or from other apps using Virtual MIDI.
Record mixes, individual tracks, or both, straight into the storage space of AudioShare (no copying of files needed), with synchronized start and end for perfect loops.
Play back recordings, soundfiles and loops as channel sources in the mixer for backing tracks, further processing or mixing. Soundfiles can be opened from anywhere, including USB drives on iOS 13 and later.
Route and filter MIDI in any way you like using the MIDI matrix. Combine and filter MIDI endpoints using MIDI buses.
Synchronize everything with the transport clock and play in time with other apps or devices using Ableton Link. Connect external music machines and synchronize them with MIDI Clock.
Includes built-in processing nodes for various stereo processing, Mid/Side balance and conversion, EQs and filters, limiting, clipping and saturation. Or use any 3rd party Audio Unit extension or Inter-App Audio effect.
All controls in the mixer can be controlled via MIDI, including parameters of hosted and built-in plugins.
