The program can “hear” the music and move the light to its rhythm: chases step on the beat, effects pulse in tempo. The heart of this system is BPM (beats per minute): the program detects the tempo and matches everything that moves to it.
📍 Where: the “SOUND” button in the program header turns on the “hearing”; sound settings are in the panel under the visualizer and in the Live sound monitor (the ⚙ gear).
How the program learns the tempo — three ways:
| Way | How |
|---|---|
| Automatically from sound | Turn on “SOUND” — the program listens to the music and catches the tempo on its own (sources are in 10.02) |
| TAP by hand | Tap the rhythm on the TAP button or the T key (at least 2 taps) — see 07.22 |
| Enter a number | Click the BPM digits and type the tempo (if you know it exactly) |
Two sound-reaction modes (the “By tempo / By beat” switch in the sound settings):
| Mode | What happens | When to choose |
|---|---|---|
| By tempo | The program averages the beats and runs chases on an even, computed tempo — even if it goes quiet for a second, the light won’t stumble | Ordinary music with a steady beat (recommended) |
| By beat | Every caught beat (kick) immediately advances the chase by one step — the light literally “jerks” on the beats | Live performances, a ragged rhythm, when you need a hard tie to the beats |
💡 Tip: start with “By tempo” mode and automatic detection — in most cases that’s enough. The fine settings (10.03) are only needed if the detector stumbles on your material.
⚠️ Note: for a chase to react to the tempo at all, it must have BPM sync turned on (see 05 Chases). Chases with a manual step time live by their own seconds.
