There are a number of features which are a huge backward step for the S2 MK2.
Firstly, the master volume knob doesnt work.
The gain knob on channel 1 reads 0 when its set on about -2
Effects rack is like going from 9/10 on the MK1 to a 3/10 on the MK2
The inability to scroll down the side bar, meaning I always have to be fiddling with the laptop, and not the controller.
Pretty disappointing, definitely will not be recommending this controller to anyone.
