I have been working on an album project from FOF with very poor tempo mapping. The author picks a bpm at the beginning, and sticks with that – so the notes are charted accurately, but seldom placed on beats, making the playing experience quite poor. Fixing this up is very slow. On the last song I finished, the bpm was set at 122, where 150 was much more accurate (though I had to make various tempo mapping adjustments every few measures). I ended up rewriting almost every note – and may as well have simply charted from scratch.
Is there a way to change the bpm from, say, 122 to 150, and have the charts changed automatically to fit?

If you highlight a bunch of notes (or even ctrl+A if it’s all of them), hold ctrl, and drag, REAPER will adjust the start and end of the notes. See the bottom of this page:

Another way is to highlight notes, right-click, and pull up note properties. Entering things like “/2” in position will change the start position of all notes by half. I’m not sure if something wacky like “/122/150” will work, but you can try!
Either way will probably let you get it close enough for quantize to finish the job.

This won’t work in one step, but you can do it over multiple steps. Using these numbers as an example: Select your notes and press Ctrl+F2 and do “/122” first, which will make them all really smushed, but still selected, then press Ctrl+F2 again and type *150. This will make all notes really small, but you can just go into the actions list (Press ?) and search for “Edit: Set note lengths to grid size”. Just make sure to set your grid to 16ths or 32nds first.
This should make the notes fit a new tempo. I might’ve reversed the steps though (might have to divide by 150 then multiply by 122, I just don’t have Reaper here atm to test it, just make sure to divide first or else your MIDI track becomes huge)
