While I’m happy to give away DrumBurp for free, it’s not free to me to develop and distribute. The hosting for this website costs money, and my time spent on DrumBurp is time I’m not spending on something else: in particular, I’m not drumming!
If you find DrumBurp helpful to you, and you’d like to say thanks, any donation you’d like to make would be gratefully received. Whatever the cost of a beer or a coffee is where you live, that’d be great!
