Frequently Asked Questions
Do I need headphones?
Headphones or speakers both work. Lower the master volume if any layer feels harsh on laptop speakers.
Will playback continue if I lock my phone?
Mobile browsers may pause audio when the screen locks. Keep the tab active or use a device that allows background audio.
How does the sleep timer work?
Start your mix, choose a timer length, then tap Arm sleep timer. Playback stops automatically when the timer ends.
