Block / Kill Specified MIDI channels

[RadekPilich]

I have a keyboard poly synth as one of the inputs and also one of the synths on one of the outs dedicated to a bunch of poly synths.

I can easily change global channel on the keyboard and play all the other poly synths.

I want to prevent MIDI loopback on the keyboard synth though, block its channel in the routing.

I know I can remap the channel to channel 16 and use it as a dump, but I would rather not waste usable channel and not send unnecessary messages in the MIDI data stream.

Can you just place a NOTEs filter on the routing between the input and that loop back output? That seems like it should work no? It will block all notes coming from that keyboard from going back into that keyboard through that routing, but wouldn't affect other routings from getting to it.
