Introduction
When sending multiple audio outputs from Playback, every possible instrument track is automatically grouped with other similar instruments into a bus output. With buses, Playback does the tedious routing work for you, so that you can start using MultiOuts right away and trust that your instruments will be grouped correctly.
Overview
Playback SmartRoutingⓇ will automatically pull from over 150 different individual instruments and conveniently route them down to 10 buses:
Click/Guide: the click track and guide cues are grouped together
Drums: All drum set tracks
Loops: Electronic percussion, some aux percussion parts
Bass: Acoustic and Synth Bass tracks
Piano: Every type of acoustic piano track
Keys: Synth and aux keys tracks
EG: Electric guitar parts
AG: Acoustic guitar parts
Vocals: All background vocal tracks
Aux: Miscellaneous instruments
Bus Routing
While using a MultiOut setup, you have independent routing control of each instrument bus by sending them out of any available audio output, mono or stereo.
There are two ways to route your bus outputs:
Head to Settings → Buses, where you can see the default bus routing for your current output device. Simply tap on any bus row to re-route that bus to a different available output.
While in Setlist edit mode and the bus mixer view, tap on any Bus fader name for quick routing access.

Bus Mixing
The bus mixer view gives you the power to change the mix of your buses, affecting all relevant instrument tracks. Bus mixes are song-specific by default, which gives you the ability to adjust buses to different volumes per song. If you prefer your bus mixes to be global across every song, this can be adjusted by disabling song specific buses in the Settings.
You can also solo or mute buses, which will affect all relevant tracks. Listen to just the guitar parts for a song, or mute every keys track in a song. If a bus is muted, all tracks routed to that bus will appear muted as well.
MultiOutsⓇ can be unlocked with a Playback Pro subscription which allows you to utilize the full power of mixing and routing with Buses.
