Hello there
I had the same problem with "freeze" but only when I edit midifiles and only in the OS 2,0 there was no problem with the 1,2,
my tempo change and the drum change also
When I edit the midifiles and save it the whole board "freeze" Would priciate if someone could do some test and see if it happend on other Audya.I have installed the OS 2,0 twice'
