Everything I have from Session Band has worked beautifully to provide a set of excellent musical tools for both study and for performance. Many of the reviews for Session Band Drums have been on the negative side. I can definitely understand this because, by itself, Session Band Drums does not offer as much as the other Session Band apps that provide drum parts, bass parts, chord parts, and much more. However, for the simple purpose I have in mind for Session Band drums, it really has provided a great tool. My recommendation is that potential users of Session Band Drums make sure, before purchasing, that they are not going to be asking too much from the app. If they want more than what Session Band Drums can provide, I recommend that they find a what they are looking for in Session Band Rock, Blues, Jazz, Country, Acoustic, Piano, etc. I hope this helps!
