I really would love more advanced control over what gets forwarded (midi thru style) and what doesn't
sometimes I don't want anything forwarded on
eg. using ableton, and wanting to light up the keys for a synth part... forwarded it on just creates a midi feedback loop,
It sends the notes back to the computer, it triggers the softsynth again, forwards the notes back to the keyboard to do the lights, back to the computer.
I either lose the ability for the keyboard to control the softsynth or I lose the ability to see the lights.
Or I go down a tangent of assigning different midi channels on the input and output........... which convolutes things with other parts of my setup.
