Metronome & tap tempo
The metronome is the heartbeat of Skratch Attach: loop recording, loop playback sync, and Follow Mode all key off it. There is no separate "sync" switch — if the click is running, everything follows it.
Turning it on and off
Two ways in, and both do the same thing: the metronome arms first — silent and ready — and your next tap starts the click on that exact beat.
On screen: long-press the TAP button, about half a second.
- The button gets an amber outline — armed.
- Your next tap starts the click on that beat — tap on the "1" and the click drops in on the one.
- Long-press again to turn it off.
On the hardware: press the right deck's browse knob (deck 2, printed SCROLL / LOAD). Press again to turn it off.
While either deck is in DVS, that knob is busy browsing tracks — hold SHIFT and press it instead.
While running, the TAP button flashes red on the "1" and orange on beats 2–4.
If you've recalled a record from the Wax-ID Library, that first tap starts the click at the saved BPM — no counting taps needed.
The same knob sets the tempo
Turn the right deck's SCROLL / LOAD knob and it moves the BPM. How far per step depends on whether the click is already going:
| Metronome | A step moves the BPM by |
|---|---|
| Running | 0.2 — fine, for tuning against a record by ear |
| Off | 1.0 — coarse, for getting close quickly |
The range is 40–200 BPM. In DVS the knob scrolls the browser instead, so the tempo stays where you left it.
Where you hear it
Never the master mix — the click is for you, not the crowd. How it reaches your headphones is completely different on the two decks.
Straight to the cue (headphone) output. Plug in and it's there; nothing to set up.
Set the click volume with Metro Gain in Settings → Audio, or reach for the deck contour knob — with no Shift held, that knob is the metronome volume. See Mixer & contours.
Tap tempo
Tap the TAP button (on screen, or the hardware button printed TAP) on the beat to set the BPM. The tempo tightens as you keep tapping — the app averages your taps and quietly discards the odd mis-tap. Pause for a couple of seconds and the next tap starts a fresh tempo.
With the metronome running, a full five-tap count (1-2-3-4-1) does more than set a number — it locks the grid to a playing record. That's Follow Mode.
FX timing and Auto BPM
Both used to sit in a row of chips under the BPM display. Those chips were removed to give the screen back to the decks — the features stayed.
FX beat divisions are set from the hardware and from the settings pages:
- Your controller's FX buttons step the Master FX division up and down
- The Pad FX division is set the same way, and on the pad-mode strip
- Both are shown on the FX and Pad FX settings pages, and mirrored to your mixer's own display where the hardware has one
Auto BPM reads the tempo from the live audio instead of from your taps. Hold the hardware TAP button for three seconds to toggle it. TAP flashes to tell you which way it went — accent colour for on, orange for off.
