command a Mac (Logic Pro) with a connection or a midi / usb

[drainomap]

thanks to all. I meant just different audio tracks that I opened in a Logic project and that I usually use live with my band, I play on the Logic and I start the base (sequence), then starting it and physically accessing it by pressing play on Logic. I would like to know if there is any possibility of controlling my entire project from my Nord Stage thus avoiding having to constantly move from the North and also use my Mac ...Maybe exist the possibility to connect a pedal switch or similar ?? I await your answers thanks

Not quite sure about that, but if you use an iPad on the stage you can use an app called Logic Remote.
