Not sure how all the connections work but as far as buttplug goes, you might be able to do something with Not A Butt Plug (NABP). I use it with Scriptplayer and my OSR2 with no issues at all.

Would definitely like to see OSR2 support added since that’s what I have. Already looks like a fun program and great job so far.
