scott..
now i know which plug ins your referring to
you wont get any disagreement from me on the "sound".
a friend of mine has all sorts of plug ins includeing those.
so yes they have a nice sound. i'm well aware of that mate.

but it was technical aspects of synth edit plug ins i understand
that is of concern and sometimes causeing daw probs.
i frankly havent followed
all the probs various people have encountered.
if i remember one aspect was multiple instances and/or multi core
operation ?? but mebe these have been addressed.

as to tI chipset, a far as i was aware most people running studios
know that a TI chipset in the host pc is de rigeur.
some people however have been lucky enough from what ive seen
to use a fw sound device with a non ti chipset.
there seems to be no rhyme or reason for it.
and ive never seen a satisfactory explanation.

i think its prolly best if andrew or someone at pg test out your plug ins
etc etc with RB n other pg products.
i'm just too busy with family n medical stuff frankly.

all the best.
