I've done this simple patching with Midi loop (midi out go to corresponding midi in) to try understanding midi flows inside a rack :
I've set in1 ch1, in2 ch2, in3 ch3.
So the messages sent from rack 2 are mixed together and all sent to the three midi out, that's it ? No way to send each out to the corresponding device ?
About rack 1, it's the same : the messages in are mixed together ? How can I - lets say - send midi in 1 to patch 1, midi in 2 to patch 2 etc... ? Filters only ?
So at last, in order to avoid mixing messages together, it seems simpler to use midi buses inside each device, instead of puting the devices in the racks ?
Thanks for your advices
