Hi jpg jelly,
Better stick to singing me I think,
What I find troublesome with many of these apps, is how deep you get in the menus and how difficult it is to get back to the channel faders, I am lucky I am on my jack jones, but imagine it must be a pain in bum when you are in the thick of it.
I suppose it's all down to experiencing yourself with the kit and such, but if you were only doing odd gigs with these bigger desks, I can imagine you would have to keep your hand in at home with the virtual sound checks?
Cheers
Kev
