Not ready for Prime Time

Midi export is flawed. Does not export correct note timing. No support I guess they don't want to hear about any problems. You can not delete empty measures. Needs realtime note entry. This app could be good with some work. As it is it is pretty useless.
Is this just another take the money and run app. Maybe.....

Would be great but....

I bought this app to help jot down and quickly share musical ideas with friends and students. Creating the files and composing is wonderfully easy, but the format of the final result is useless. Printing is not functional and viewing what you have created shows you one measure per line, making it unreadable. I hope this gets fixed because this could be "the next great thing" for musicians! For now, it is a complete waste of money (for me).
