MIDI link parameter modulation: Parameter locked to last received MIDI CC value

Hi! I'm trying to do automation via the use of MIDI CC via MIDI link parameter modulation. It works fine but unfortunately I can no longer change the parameter inside the plugins own GUI. It seems Reaper locks the parameter value to that of the last received CC-value via the MIDI link. If I try to change the parameter using the mouse in the GUI, it will simply jump back when I release the mouse button. I'm not sure why Reaper does this? It doesn't seem to be a very useful behaviour, since it immediately locks the parameter even before I've recorded any CC into a midi item. This makes it hard to play around with the params to find something suitable before recording the midi CC. Is this behaviour by design? Is there any way to disable this "locked parameter value"? :0) Cheers, Loopa

I'm glad you reported this bug - I have also encountered it.

I just found ReaLearn! It pretty much does what I wanted MIDI Link parameter modulation to do: It works really well! (although it would be nice to fix this bug in Reaper too :) Cheers, Loopa

Has this been fixed or some workaround found (besides ReaLearn)?

When you assign CC via Parameter modulation/MIDI link it will bind the control to value/offset/scale set in the param mod window. Just use Learn instead for normal behaviour - absolute with soft takeover enabled.
