Ok, at last could test. Giving some feedback now:
Ok first thing I noticed is lag. I am sending simple notes to reaper. Lowered my latency in ASIO settings. Tested with ableton live and no lag there. It also misses some notes if played fast.

If i get into the config, I have to restart. It loses focus from the current track selection and can not recover it back if not restarted. I do can select a new channel but not the one that was selecting while changing configs.
The selected track by mouse in reaper does not update to be the active track in push 2 accordingly. I have to follow with the push 2 keys in order to reach the desired track. Dunno if that is a feature but surely would be better following up your actions in reaper.
As a suggestion. Would be nice to have the transformator program minimize to system tray area and not having the cmd bat window open at all times. Just an idea to keep things tidy.
I am also attaching logs that show some trouble when getting into config menu and changing stuff there.
I hope this can be of any help.
