I'm not sold on GigaXXX.
1) Company must not be confident in their product since there is no demo version and no online manual to peruse before buying.
2) All demo's are mp3's which means there is loss in the compresion and you can't analyze the demo (trusting that it was really generated by Nemesys product)
3) No reputable authority has given it better marks than a dedicated high-end sampler.
So there you have it...believe the hype or not.
