Port Filtering - add midi channel?

[Jesse Johannesen]

Maybe I shouldn't take care of that, but I have just idea to reduce of "flying" midi commands to output devices. Some of gears use only one, or two input channels. As there is input/output filtering for CC/Note/Clock etc comments, it could be useful (for "cleaning" / optimize reason) to select active midi channel(s) and all different that defined will be ignored. 

Now if i allow routing from my sequencer (for example 4 channels CH1-CH4) to all synths, this will send every midi commands to each of them, for all channels. If I define that my synth on OUT1 use only CH1 then all commands sent to CH2, CH3, CH4 will be ignored on OUT1.

I think this is the same thing as using ChMap mod with Exclusive= true. With this Mod you select the 4 midi channels you want to pass through, and where you want them sent, (and this can simply be 1>1, 2>2, 3>3, 4>4 if you want,) then if you set Exclusive on it will block all other routings on other channels. It's still not perfect in my eyes, because I don't think you can route less than 4 channels, but with a little planning and creative thinking you could block more with a second Mod slot if needed. No current way exists for routing more than 4 channels currently, however.
