Review for Play drums! by manch455
Rated 4 out of 5 stars
Absolutely need support for pressing two buttons at the same time. This Add-on is so limited because of the fact that you can't play two or more sounds at the same time. If this is fixed i can imagine this really taking off.
This review is for a previous version of the add-on (0.4.1-signed.1-signed).To create your own collections, you must have a Mozilla Add-ons account.
