Im using version 1.6 on iPhone 5s and IOS 8.3. Its a great synth app, very flexible and capable of creating a wide range of sounds and soundscapes. It gets 4 stars and not 5 due some glitches. First, in the File menu, there is no delete command, and the Delete button in the File Open screen doesnt actually delete the selected file. Second, in the Node Edit screen, double tapping the value field switches it to Num mode -- tapping it again to edit the value causes the app to crash. Finally, there is no way to enter or edit information about the file. The Information button doesnt work and for some reason the app automatically inserts descriptions from files that come with the app. I hope these issues get fixed.
