Not made for iPhone
Impossible to play single note on iPhone. They had a button for this on sound prism pro (along with other buttons now missing) but got rid of it and used the space for the expression thing. I thought it would've been nice to have an option between the expression or the buttons. Sounds are there but too .... crazy but you can make it work. Bottom line. Got an iPhone? What less features and more strange sound presets? If you have Sound prism pro don't get this. PS. link is cool and works well thooo
