With a name no other than iSynthesizer can you really go wrong especially when it’s FREE? Well you can. Sounds great but there is no midi support and it’s upside down when my ipad is in the Alesis iO Dock. Tried flipping it but no go. Anyway , if those things don’t matter to you then get it because it’s free =)
