Not playable on iPhone 12
Apple’s swipe up interferes. Only supports right handed Landscape mode. Opening Samples window, it overlays the screen preventing a double-tap to close! It wastes screen on the right side. The audio engine still crashes requiring stop/start of app. I did makes some wild sounds but it’s not actually usable on the iPhone 12. Good news that you can record and export aif files. Too bad it’s bad. Deleted. Wasted money.
