Pianoteq 8 Guitars -- MIDI Strumming Device/VST/Advice

As title, is there a convincing (and feature-rich hopefully) guitar strumming/playing engine/VST available for manipulating Pianoteq's guitar via midi?

I demoed a few in the past, however most if not all I tried were proprietary only.  For instance, Amplesound was amazing, however if I recall correctly various playing techniques (strums, placement, etc) were limited to its own VST as it was primarily keyswitches kicking off various functions within itself.

Any help would be very much appreciated.
