no. as long as there is only one out connected all outs will be routed to this output. if a voice is routed to a not connected output, it is routed to the nearest connected one.
not making it global allows you to store different FX routings for different presets. My thought was if you have a kit where you like reverb on an instrument, you route it to out 2. on the next kit you don't want reverb, so you can save the routing to a different out.
