Customer Reviews

Great Drums- needs Audiobus!

The S-4 drum has great sounds and it's easy to switch from one drum set to the next without missing a beat. It would be a 5-star app if it were brought up to date with Audiobus. Another improvement would be a way to import drum sets (maybe an in app purchase?) this is my favorite manual drum app, I just don't use it anymore because it lacks Audiobus. Too bad...

Abandoned - try their other apps

This particular app is no longer relevant in 2014. I actually really the feel of the drum pads - they are even velocity-varied depending where you press! And the rock and pop kits sound great. But the app has no AudioBus or export feature of any kind. It isn't even adjusted for an iPhone 5 display. This company has made some newer apps, which are imperfect but also underrated. Check out Chauliodus Bass Synth and S4 Rhythm Composer Pro.
