Bc2000 (for the BCF2000 & BCR2000)

ok, i figured it out myself. the R and W buttons should have been enabled on MIDI track to be automated as well, instead of enabling R and W on VST Instruments track of the MIDI, Olga in this case. as you can see in the picture, the blue automation bar for these two parameters, filter resonance & filter cutoff frequency that is, are still on VST Instruments track, thats where i got tricked initially, because these two bars were moving when i was tweaking these knobs with my mouse and i thought its the same automation place via MIDI controller as well.
