MIDI problems

Hello Dear Friends My OSX is now Yosemite but I have had this problem also with Mavericks after the 4.73 version of Reaper (i think) I have this strange problem: I have 2 VST (kontact and Trillian) that runs without problems in my mixer. But when i am in play, I can see one of these VST (Trillian) in the Meters as a meter MIDI variation. Before this version (4.73) any of all VST Virtual Instrument didn't show MIDI meter variations. Why now I can see a meter MIDI variation only on Trillian (and not on Kontact) ? Please tell this problem to your Technician Stuff in order to resolve this issue. Many Thanks and sorry for my bad English (I am Italian)

The MIDI indicators on Reaper's track meters are post FX - means they take their info after the plugins, at the track's output. Kontakt will swallow all MIDI data that goes into it, no MIDI data will be at Kontakt's output. Therefore Reaper's MIDI indicator doesn't show anything. Maybe Trillian passes the MIDI data through, so there's a readout.

^^^^ I get the MIDI indicators on a Kontakt track here. ;) (even without setting the choice in Kontakt's Options)
