OK, So all is working pretty much as it always has here, but I have moved on to BIAB-VST 4.0 (BIAB 2022). I still can move chord chart between Reaper, BIAB-VST and Scaler with only minor adjustments needed. Those occur when the nomenclature for the chord is not recognized by one of the programs. For example Scaler and Reaper both recognize Fsus4, but BAIB-VST does not know this sytex and leaves that bar blank. See if this picture is clear showning the same chord chart (started in Scaler) draged to Reaper, then from Reaper draged with (Ctrl-Alt) and dropped into BIAB-VST. It does work.
