Mostly good.

This app is really great for creating music, I have musical training but Ive seen people without it make fairly decent tracks with it as well. The layout is quite intuitive and appealing. My only problems are that all of the instruments sound very electronic, there really are no acoustic things (except for a grand piano, which is very good) so if you want to make an orchestra, rock, or really any genre other than EDM techno or house its not very easy. Once there are more instruments that sound acoustic and good itll be a 5-star app (the instruments it does have do sound good for electronic instruments though)

Clerith FTW about Beatwave, v2.6.1
