Fantastic App

This is a fantastic app for making pads and ambient sounds. The presets are wild and you can make some super crazy sounds of your own. You can record what you play into garageband. Endless fun.

Is not working anymore! The splash screen appears for a second, then disappears. Strangely, ( and this not the only app that I’ve experienced this with) the screen is there in the background. Otherwise, the preset system varies from version to version, on my iPhone, I can find different folders, on the iPad there is only one folder. Yes, this old app has always been ahead of its time… I find myself using the working versions of it still.
