RoutingAudio, MIDI, busses and external gear in Ableton Live
Live routing is simple once you think in jobs: audio comes in, instruments create sound, return tracks create shared space, and external gear needs a clean round trip.
1. Audio tracks
Create audio tracks for vocals, guitars, resampled loops and hardware returns. Set monitoring deliberately: Off for playback, Auto for recording, In only when you need live input through effects.
2. MIDI and instruments
Use MIDI tracks for Drum Rack, Simpler, Wavetable, Drift, Meld and third-party instruments. Freeze or flatten heavy instruments once the part is right so the arrangement keeps moving.
3. Busses and sends
Group drums, bass, music, vocals and FX. Use return tracks for shared reverb, delay and parallel processing instead of inserting a new effect chain on every track.
4. Outboard routing
Use External Audio Effect for hardware inserts and External Instrument for synths. Measure latency, keep a clear input/output pair for each device, and print the hardware pass to audio before final export.
