MIDI Filters Per Channel

[Lizard of Oz]

The port filters page is for a scenario where you have something like a drum machine on an input that is dumping out MIDI clock and note messages that you don't want to go anywhere, you can set up a global filter on that input for clock and MIDI notes. Or in a situation where you want clock and real time messages to go to a sequencer but never MIDI notes, you could set a global filter on MIDI notes, etc. Vert useful, just not for every scenario.

The manual explicitly states users should take care not to overload connected devices, so I think that would imply that filtering channels per output and per routing is required for many scenarios. Channel filters for routings, inputs and outputs would open up a lot of things that are currently cumbersome, and would make the Channel Map modfiers available for actual channel mapping. 

See my comment in the other thread about port filters how that might be implemented without too much hassle.
