So as you can see in the video, when I let go off the sustain pedal, the note still hangs, And the opposite also happens, when I depress the sustain pedal, it shows CC64 on in the Midi control but it doesnt work in the plugin.
Somewhere between Reaper and Reason Rack Plugin isnt processing the on/off properly.
It doesn't happen to any other plugin though, only with RRP.
