I am using imix16band on iPad Air 2 on iPadOS 13.4.1
I loaded some audio clips in from Music playlist (used to be iTunes)
osme cups are fine but some clips will just crash the whole app.
after the crash, when I opened up the app again, some previously
loaded clips were all gone and I have to reload everything again,
this is quite a weird issue. Why some audio clips are loaded while some are not.
