It is only in GS3 Orchestra that you have to option to insert the GigaPulse Pro plug in on any audio channel that you want in the DSP mixer. If you have Ensemble or Solo GigaPulse SP will only show up on Instruments that have GigaPulse encoded into the .gig file. Such as the GigaPiano II, NDB Cathedral GigaPulse Module.gig and if you expand the LSAD Demo Pool.gig you will notice 3 instruments Room Color – Big and Beefy, Room Color – Thunderous, Room Color – Small and Tight that if loaded in Ensemble and Solo will invoke GigaPulse SP.
