Backing Tracks

Upload audio files to play alongside your band during performance — click tracks, synth sequences, orchestral parts, or full backing arrangements.

Song-Level Backing Tracks

Each song can have a backing track attached:

1. Open a song
2. Go to the Backing Track section in the editor
3. Upload an audio file (or pick from Apple Music / YouTube — see below)
4. The track is stored and ready to play

Per song, configure:

• Auto-trigger — Start playback automatically when the song begins
• Loop count — Single shot, 2x, 4x, 8x, or infinite loop
• Trim timing — Set in/out points without re-encoding the file. The original audio stays intact; the player respects your trim points on playback.
• Tempo — Play a track slower or faster, 75% to 125%, while its key stays put. See Tempo & Pitch.
• Pitch — Shift the key up or down by up to 12 semitones while the tempo stays put. See Tempo & Pitch.

Step-Level Backing Tracks

If you use song steps, each step can have its own backing track. This lets you trigger different audio for different sections of the song — a string pad for the verse, a synth arpeggio for the chorus.

Per step, configure:

• Auto-trigger — Start playback automatically when the step begins
• Loop count — Single shot, 2x, 4x, 8x, or infinite loop
• Trim timing — Per-step in/out points
• Tempo — Per-step tempo, 75% to 125%, key preserved
• Pitch — Per-step pitch, up to 12 semitones either way, tempo preserved

Tempo & Pitch

Tempo and pitch move independently — slow a track down to learn a part without dropping the key, or shift the key to fit a singer without changing the tempo. Both live in the Backing Track section of the song editor, on songs and on individual steps:

• Tempo runs from 75% to 125% of the original. Selecting Original clears it.
• Pitch shifts up or down by up to 12 semitones. Selecting Original clears it.

The adjustment is a property of the track, so everyone playing it hears the same tempo and key through the PA. It applies live in the editor preview and in perform mode. Larger shifts add a slight granular texture to the audio, so most bands stay within a few percent of tempo and a semitone or two of pitch.

Sources

Backing tracks come from two places:

• Direct upload — MP3 or WAV file, max 50 MB
• Existing file — Re-attach a backing track already uploaded to another song or step in this band

That’s the full set of accepted sources today. Apple Music and YouTube searches in the song editor populate the song’s Media URL (a reference link), not a playable backing track. YouTube audio download and stem separation are part of the multitrack subsystem, not the backing-track flow.

Playback

Backing tracks play through your device’s audio output. Use your device’s audio settings to route output to speakers, headphones, or a dedicated monitor mix.

Transport Controls

• Play / Pause — Start or pause playback
• Stop — Stop and return to the beginning

Transport-Synced Start

When the click track is running, backing tracks can be configured to start on the next downbeat rather than immediately — keeping audio locked to the metronome. Toggle Sync to Transport in the backing track settings.

Click Track Integration

Backing tracks work alongside the built-in click track. The click track provides a metronome at the song’s tempo, while backing tracks play your audio content. Both can run simultaneously.

Enable the click track per song in the song editor. Configure click track settings (sound, volume) in Settings > Audio.

Audio Routing

Route each bus to its own output in Settings > Audio — separate device pickers for Click Track, Backing Track, and Multitrack. Put the click in your earpiece and backing tracks through the PA, or spread them across a multi-output audio interface. On desktop, the click can be confined to the left or right channel.

Backing tracks and multitrack stems never play over each other: while the multitrack panel is open on a song, the backing track won’t auto-start, and starting the backing track closes the stems player.

Storage

Backing tracks are stored securely in the cloud and sync across devices. Before a gig, run Preflight on the setlist to make sure every track is cached on the device you’re bringing.
