As far as process/replacing goes
Insert plugins call process(),
out+= effect..
where as send plugins and vst-synths call process-replacing,
out=effect.
i've noticed some synths haven't implemented the process-replacing and
programs like Acid 4.0 cant use them..
i'd suggest calling _pluginname_->CanProcessReplacing(); or something
whenever create an insert effect to see which Process to use and how to
hande the output/mix..
cheers [3]
