vintage.
yes rb is very good at midi.
ive used it many times over the years for such.
(also audio, many many times.)

re rb. what you might do also is talk to pg user rharv.
as far as i'm concerned rharv is the " pg guru" on rb/powertraks.
if he has the same win os version/update as you and has no probs; this aspect might be worth exploring.

irrespective of any daw you use i still suggest a good asio low latency sound interface.
and a properly set up (off the net) pc with 2 ssd drives.
lots of ram etc.
it still amazes me that yonks ago, it was a given that one kept ones studio pc off the net, yet , in this era its
different.

forte dxi should load in reaper. so run a test.
in reaper prefs you need to add forte dxi.
then on a reaps midi trak select the forte dx plug in.

i dont want to push reaps at you, but if you want to explore reaps more , go to reaper.fm , then clik on VIDEOS to see all its features, includeing midi etc. and see if its for you.

(also loads of vids on you tube. and also you tube has loads of vids on pc set ups/configs/how to's plus reviews of usb sound devices.)

best.
