Did they even test it?
Attempted to run this on my iPhone6. Crashed several times. Importing samples worked, in theory. They showed up, but the ends of the decay were truncated.
I wouldn’t say this is the worst music app I’ve ever tried to use, but it’s close. Odd, too, as the iPad version seem(ed) much more stable when I last used it, but I was looking forward to having something on my phone I could use.
