this is just the thing I am trying to reproduce with Scaler and AAS Strum GS, so please read this proof of concept that goes in the that direction AFAIK
With this setup you can actually have Scaler pressing strings with its virtual left hand making chords, and a 2nd Scaler doing finger picking with its virtual right hand; or you can use your real right hand to tickle the proper keys
Clearly, all that may work or not with your guitar plugin
