[LAU] LV2 hosts and MIDI channel

hi list, I am looking for a way to let LV2 instrument plugins respond only to a certain MIDI channel. This might be possible in an integrated environment like ardour3 or qtractor - I did not investigate this since I need something like a standalone host (to add LV2 support to chino). I found the following hosts capable of loading instrument plugins: lv2_jack_host zynjacku ingen but found no way of assigning MIDI channels in either of them, they all seem to listen "omni". Ingen maybe comes nearest. I looked at all the internal objects but found no solution (e.g. their properties dialogues are incomprehensible to me). At least it allows to put several 'event inputs' that appear as separate jack-midi inputs, so I could prepend a filter. If there is no other way, I'll go that one. If I missed something and someone comes up with a simpler solution, I'd be happy as well. greetings, d
