What this node does

Click Track produces a metronome. Give it a tempo, a time signature and a number of bars, and it renders a click audio track (accented downbeat, plain off-beats) through the same SoundFont synthesizer the rest of the music lane uses. Optionally, wire in a labels text input to place the clicks at specific labelled points instead of on a fixed grid. Press ▶ Run to render on the backend. The node emits two outputs: the audio click track, and a performance payload describing the clicks — the same kind of performance Score Synth and other stages consume, so the click can double as a timing reference for other renders.

​
When to use it

  • You need a metronome track to record or align against.
  • You want a count-in or timing bed at a specific BPM and meter.
  • You have timing labels and want clicks placed at exactly those points.

​
Parameters

​
bpm

Tempo in beats per minute, 20–400 (default 120), in 0.5 steps. Ignored when a labels input drives the clicks instead.

​
beats_per_bar

Beats per bar (the top of the time signature), 1–12 (default 4). The first beat of each bar is accented.

​
bars

How many bars to generate, 1–256 (default 8).

​
soundfont

Optional SoundFont file name from the resource library used to voice the click. If blank (or not found), the synth’s built-in click voices are used.

​
labels (optional input)

An optional text input, type COMFYTV_TEXT. When present, the click track is built from these labels (clicks land at the labelled positions) instead of from bpm/beats_per_bar/bars.

Tips

  • Leave labels unwired for a plain grid click; wire it when you need clicks at irregular, labelled points.
  • The performance output can be fed to Score Synth or used to line up other stages to the same grid.
  • Add a SoundFont only if you want a specific click sound; the default works out of the box.
