(but no native version, I think.)
I have the 1st edition and converted everything with Translator to Kontact format. It's pretty good - a few translation issues, a few features lacking from Kontact (multi-dim layering) but it works beautifully by and large and Kontact is:
1. a boatload cheaper than giga
2. voices limited only by RAM and CPU because you can have as many instances of Kontact as you wish.
3. (as I understand from recent postings) Kontact can use most of 2 gigs and giga only most of 1 (I may have misunderstood this, please feel free to correct.)
4. Much better, cheaper, more powerful DSP effects.
5. Integrates into your sequencer
6. Easy to run on a single machine
7. The Kontact upgrade at the end of this month (never buy a product on upgrade promises but here's the rumor) will natively support giga format so (i hope) no translation needed. (WHEW! Disclaimer! I may be talking trash. Not a low fat food. Not responsible if you put out an eye with this information.)
I can't speak to the pros of giga because I've only used giga32 and was so unthrilled that I didn't bother going that direction any further. I know people love it though. I think that giga's streaming and RAM usage is a little lighter. And giga3 is on the way, but the timetable is unknown and, as I said above, never buy software on upgrade promises.
just my $.02. if giga3 is everything people say it will be, I may switch. But the short answer is yes, you can run it on Kontact with some additional effort and you will get fine results. Search for KingIdiot's posts for tips on Kontact + vsl, also. But Kontact/VSL support is community-based, not corporate, since they don't release such a version, so it ain't a free ride.
(as a personal aside, I just did my first gig with Kontact/VSL and it sounds really good. Every note you play is like a gem that you could just sit and stare at for hours. I'm looking forward to the Kontact upgrade and buying more ram for my computer - i've only got 512 - but I'm really happy with the setup I've got.) (SX/Kontact/VSL).

p.s. this wasn't a flame against giga. I would love to hear the pros of gigastudio, but please don't turn this into a flame post. merci.
