At 60 BPM every quarter-note beat lasts exactly one second, making the internal spacing easy to hear. Open the tool, set 60 BPM, and move from 1 to 2, 3, then 4 clicks.
Anchor the beat
Listen to beat-only mode first and tap one relaxed movement per accent.
Cycle through 2, 3, and 4
Keep the movement on the accent unchanged while the internal clicks move from halves to thirds to quarters.
Hold each grid for eight beats
Stay with each subdivision for eight accented beats before switching. Count the first four aloud and the next four silently. If your tapping leaves the loud click, return to beat-only mode, recover the one-second pulse, and repeat that subdivision.
