Bear with me as I come from the ancient analog world. Just got a Mackie HUI (I know it's old but was a great price) Love the layout meter bridge etc. Regarding the midi connections: If say I am using software synths / samplers via midi key controller to pc where does the HUI connect midi in / out on the pc ? I do have a JL Cooper MSB midi switcher/ processor in my rack But am confused on the whole midi set up for this scenario. Appreciate any help.
