You can publish your PMA(s) on Buttons Play Music. We are a Canada-based company, but we work with designers and developers around the world.
After you send us your PMA(s), we’ll take a look. We publish only some PMAs.
And yes, we do share sales revenue with PMA programmers.
The best way to contact us for this is to email email@example.com and use “PMA offering: Title of your PMA” in the subject line.
