[RWP] quantization of midi in Reaper

[Indigo]

I jusst learned that, according to the online Cockos forums, no version 
of Reaper, up to and including 4.22 can quantize midi from the inline 
midi editor.
A grid of vertical lines that cross the time line is required; and the 
lines represent  sixteenth, eighth notes etcetera, divisions of the 
measure; and, from the inline editor, you can't change the project grid.
You must go to the piano roll midi editor to reassign the grid.
ReaAccess's midi editor is based on the inline editor, and that is the 
reason I couldn't get quantization to work; even though I tried 
reassigning the grid from the inline midi editor, by changing number of 
grid lines per measure in the options Snap To Grid settings.
In  the forums I found sighted users complaining about this bug, or 
peculiar method of assigning grids; way back through various versions, 
and nothing has been done about it so far.
All quantization is based on project grid, so why should there be 2 
different places  to  change the project grid?
I haven't tried to get inside the piano roll editor yet; but; if Sonar's 
piano roll editor tells us anything; it can be a matrix of bit map 
horizontal and vertical lines that the screenreader can't cope with, and 
who knows where to change the number of grid divisions per measure.

I'm hoping there is a work around someone here has discovered.
Has anyone had success in actually doing midi quantization?
How did you do it?
Thanks,
