Hey π, I'm **Seb** and I'm creating *muted.io*

**I need your help!** If you have a few
dollars to spare, I would be incredibly grateful if you could
donate to support the development of muted.io. π

I estimate that I would be able to fully support myself if only about 3% of the site's visitors made a one time $4 donation.

My ultimate goal is to be able to focus my time on creating more free musical tools, and your donation will go directly towards making that goal a reality. π
