Ratings and Reviews

Bug notes


It is a very well presented app but I cannot find the instructions to fully utilise this applications. Also the pitch bar isn't staying in place when I change the pitch. It always reverts back to normal. Please check these out and I hope they will be addressed by the next update.



This is, in my view, one of the most playable iPad instruments yet, and the most complete synth emulations one could imagine. It's keyboard is the most responsive I've seen. The patch-editor upgrade is quite expensive, but definitely puts the icing on the cake.

Worth it's value


Definitely worth the money, only 1 dollar! Compared to other synthesizers this is considerably the cheapest on the market, and still was great for a beginner like me
