Similar issues were posted before but this one's specific to REAPER.
When I use any FF plug-in, I can adjust any parameter using mouse click, while controlling the transport functions such as play/stop simultaneously with my keyboard. However, when adjusting parameters with the mouse wheel, I can no longer use the transport keys unless I manually focus back on the transport, because FF steals the focus.
This issue makes mouse wheel control entirely unusable for me, since I have to constantly be playing/stopping when I make adjustments. I don't have this issue with any other plug-in. Take TDR Nova for instance; it allows simultaneous mouse wheel adjustment and transport control (so it should be possible for FF in theory).
I would appreciate a ton if this issue is addressed, for this is not the type of limitation one would expect from FF. Cheers.
