from a software engineering standpoint i would be very surprised if
pg devs would want to do a complete plug in version.
there prolly are major software engineering issues that would need to be overcome.

there is also the underlying aspect of pc hardware architectre to consider.
cos not everyone has powerfull pc's.
also one needs to consider disk drive technology as it stands today.
in theory it all sounds nice...
but the devils in the details from a systems assurance aspect.
some people have trouble on their systems running sometimes simple plug ins.
running auto accompany as a plug in is much more complex.
for example what if someone has a crummy slow old disk drive with
slow seek times and/or limited real memory. for example.
man..drag that old celeron with the clunky drive outta the closet
n lets rock out..lol.
)ps..and yes i know jammer offers a plug in...
but not with real traks going full tilt.
different story useing all midi versus real audio session traks.)

retired puter engr....powertracks on amd......NICE !
