Oh my mistake... your are absolutely correct about the R and RB versions and the MCP resize! Plz forgive me
May I suggest that in your reaper for testing you do make and save one screenset that does use the MCP as a track inspector?
If you have never done it... here are the steps:
1-dock the MCP
2-drag and drop the postion of that dock to the left side of the TCP
3-Set up the MCP so that the Master track is floating in it's own window
[I put that Master to the left of everthing but others prefer to the right]
4-On that Master clk to where you get the settings for the MCP and have scrolling ON but have show multiple rows OFF...
5-resize the dock width so that it is only one MCP panel wide at the left of the TCP
The result we are after is the when we clk on any given TCP panel, we get the single MCP for it at the left of the TCP
IF that is all good save it as a screen set so you can call it up whenever.
I just offer this as a suggestion knowing that many users do set up this way so it might be handy for you to see how diff layouts work in it.
