Re: GigaPulse VST -- Is it included in GS3 Orchestra?
My understanding is that GigaPulse Pro is a different product and only operates within Giga3 Orchestra. If you don't use Rewire AND you have a GSIF2 compatible board, you reportedly can send you audio from a sequencer into the Giga channel and process it with GigaPulse. To use GigaPulse as a standalone VST in a sequencer requires the (not yet released) GigaPulse VST product.
(Note: You can export your sequencer track to a broadcast wave file, load that in Giga3 Orchestra, and process it with GigaPulse Pro.)
