Seekbeats is pretty much perfect as a synthesis beat creation app... which I believe is the authors original intent. Seekbeats sounds great, is easy and intuitive to use, and creatively inspiring. Ive been using this almost solely for beat creation since I downloaded it. The small gripe I have is that while composing I must open another app to play melodic sounds with... which means I must open Audiobus to synch the two apps. Three open apps drains the battery pretty fast and slows down the creative juices. Much faster than if simple melodic sounds could be programmed directly in Seekbeats. This wouldnt be an isissue if Seekbeats didnt sound so good, with depth and presence. Either my ears are failing me, or the delay integration isnt very good. When I adjust parameters related to delay I dont hear a difference. Reverb would be nice as well. In conclusion: for synthesis beat creation, Seekbeats is impressive while remaining accessible and intuitive in all the right ways. That that it does so much, so well, leaves me hoping for an expansion of it capabilities to include simple melodic programming and better delay integration. I highly recommend this app.
