After some initial hiccups in getting GS3 up and running, I finally have it going (registered, updated and all). Still waiting to get Cubase SX3 (in transit).

In the meantime, I'm sketching out some idears. I'm using an MPC2000 (I'm a hip hop guy) to sequence for now until Cubase gets here. Once I get Cubase, it's going on the same PC as Giga. I'm finding that without having another program running that I'm able to basically do whatever I want with regards to loading sounds, gigapulse, & polyphony. It doesn't seem as if I'm putting my PC through any strenuous activity (which is great). Will this change once I get Cubase?
