Editing a song

Click a song to open it. The header carries its video and details; below that is the transport, then the timeline with one lane per stem.

The mixer

Each track row has:

  • M / S — mute and solo.
  • 🎧 — send this track to the B.Beat's headphone (AUX) output, on top of its normal output routing. The two are independent: a track can go to Out 3 and the headphones. This is where click and cue tracks usually want to be if you monitor from the unit itself.
  • Volume — the fader, in percent. 100% is the device's unity.
  • Group — which mixer family the track belongs to (click, DRUMS, TRACKS, FX…). Families set the output channels, so assigning a family routes the track.
  • Out — the physical output on the B.Beat. Setting a family usually sets this for you.
  • ± semitones — transpose this one stem. Baked into the audio when you save.
  • vox — formant preserve, for natural-sounding vocal shifts.
  • dB — clip gain, also baked in on save.
  • ⇄ — replace this stem's audio with a new file, keeping every setting.
  • ✕ — remove the stem.

Families appear as chips above the tracks. Click one to mute the whole family in this song. Manage them — add, rename, recolour, set output channels — under ☰ → Settings → Families. The device's own Disable switch is there too; disabling a family silences it in every song, library-wide.

The timeline

  • Drag a stem left or right to nudge its start (its lead).
  • Trim handles at each end, with fades — all non-destructive until you save.
  • Grid locks to the click track, so nudges and loops land on the bar.
  • Zoom with the slider; click the readout to return to 100%.
  • Markers — right-click the marker lane to add a section marker (Verse, Chorus…). Or press M during playback to drop one at the playhead.

Transport: Space play/pause · ← → step one beat (Shift for a bar) · Ctrl/⌘+Z undo.

Video and images

Drop a video on the song, or click the preview window to upload a file or pick from the library — media already in the backup can be reused without re-uploading.

  • Drag the video lane to align it against the audio.
  • Loop video for short clips that need to cover a long song.
  • Play video audio lets you hear the video's own track while aligning it to the click — a preview aid only; it is never part of the mix.

The Media manager (📚 Library → 🎬 Media) lists every video and image with the songs using it, so you can see what's shared before you change anything.

Song-level controls

  • Song transpose — shifts the whole song. This one is native on the B.Beat: the device does it live, so it stays reversible rather than being baked into stems.
  • Start / end offset — trim silence at the top or tail of the whole song.
  • Notes — pin a note on the song for your bandmates; they see it and get an activity ping.

Reaper round-trip

With the agent running, open a song in Reaper with its stems and video already laid out, work on it, render, and pull your renders back in. Renders land in <project>/rendered and re-import against the tracks they came from — including tracks you added or renamed in Reaper.
