No. Browsers limit autoplay, and the recipient starts the music with the Play button.
Can I play several notes at once?+
Yes. Activate multiple rows in the same beat to create a chord.
Is an audio file uploaded?+
No. The link carries the note grid and tempo; the browser synthesizes the sound locally.

Yes. The tempo slider runs from 60 to 180 beats per minute.
