Wow 
I work a lot in midi and vst instruments (HALion 5 being the only one) 
There is nothing out there that can come close to this powerful dual ,
looking forward to 7.5 and the full Groove Agent 4 when it comes out as my second plug in,
in the rack… Padshop Pro Retrologue get used a lot as instrument tracks
looks like 7.5 has a new way of doing this…
Not a fan of the SE plug ins 
and the SE name
