I bought iRig Stomp IO that comes with AT 4 Deluxe. I installed it on my MacBook Pro and all seems to work pretty well apart from one thing - the tuner. It works just fine when started from within the app but if I use the board (switch 3 - press and hold) then it works only until I press the switch 3 again to go back - at that point the app seems to lose connectivity with the board.
I need to unplug it and plug it back in - it happens every single time so it's easy to re-produce.
I also have AT 4 on my Windows 10 machine and here the problem described above doesn't exists - switching to tuner (and back) with the switch 3 works fine. However, I have a different problem there and it's the sound. After playing for 5-10min or (sometimes longer) the sound starts to go fuzzy and flat until... (wait for it) I move the mouse - after moving the cursor all goes back to normal for a few minutes then it goes again..? I also noticed the sound volume changes randomly, going up or down. Again, this is not happening on the Mac.
Anybody has any ideas?
