## Description

AUM — Audio Mixer is a flexible hub for configuring complex audio routes on your device. Connect inputs and outputs, Audio Unit extensions, Inter-App Audio apps, Audiobus, and soundfiles, with built-in signal processing to shape the signal. Route everything to anywhere using mix busses, effect sends, and multi-channel audio interfaces. Play hosted synths with the built-in keyboard or external MIDI controllers, or sequence them with AU MIDI plugins or Virtual MIDI.

Record and playback: record mixes or individual tracks straight into AudioShare storage with synchronized start and end for perfect loops, and use the channel sources for backing tracks or further processing. The MIDI matrix lets you route and filter MIDI between endpoints, while Ableton Link keeps everything in time. Built-in processing covers stereo, EQ, filters, dynamics, and more, with full MIDI control of all parameters and optional TimeOffset for precise alignment.
