On the app, go to Settings (gear icon) → Audio. Scroll down to Quantise Performance, then turn on Snap to the Beat.
When Snap to the Beat is on, STEM.FM waits until the selected beat or beat division before muting, isolating, or swapping a stem. For example, if you tap to mute the vocals between beats, STEM.FM waits until the next selected point before muting them.
You can choose when the change happens:
- Bar: waits until the start of the next bar. This is the longest delay.
- Beat: waits until the next beat.
- ½ Beat: waits for half a beat.
- ¼ Beat: waits for a quarter of a beat. This is the shortest delay.
