Sound Monitor (Kick/PLL)

The Sound Monitor shows how the program “hears” the music: whether it’s catching the kick-drum beats and whether it has locked a stable rhythm. This is the sound setup and diagnostics window — use it to tune beat detection for a specific room and track.

📍 Where: Live → the right column, the “Sound” block (below BPM; visible in DJ mode).

What the indicators show:

Indicator Meaning
KICK Lights up yellow on each caught beat (the kick)
Beat/phase bar The fill is the kick level (how well the beat is “heard”); the green marker is the expected beat (the PLL phase)
LOCK Green — the beat is locked stably (the PLL caught the tempo); “…” — searching

Fine-tuning controls (the set depends on the “By tempo / By beat” mode):

Slider Mode What it controls
Sens. By tempo Detection sensitivity (×1–×5) — raise it if the beat isn’t being caught
Threshold By beat The level on the Kick scale (0–100%) below which a spike doesn’t count as a beat
Low both The lower frequency bound used to look for the kick
High both The upper frequency bound

The gear button opens the full sound settings window: source selection (microphone / system / MIDI), the “By tempo / By beat” mode and all the faders — the same as what’s available below the visualizer.

💡 Tip: if the light “isn’t hitting” the kick — first raise the Sensitivity. If that doesn’t help — play with the Low/High bounds: the kick is usually in the very lowest frequencies, so a narrow low range often catches it more accurately.
⚠️ Note: when sound is off, the block shows “Sound off” — you can turn it on and pick a source via the gear ⚙ or in the BPM panel.
