I just talked to Nemesys about the giga studio and I got a little info about it that I want to share with you . The giga studio will give you 160 voice polyphony, but the tech that I talked to said they got that many voices running it on a AMD 800 athalon k7 . I mentioned that I have a pen 3 450 and my friend has a 600 pen 3 , and he said the pen 450 should get about 96 voices and the Pen 3 600 about 128.
Also he mentioned that the upgrade from giga sampler to giga studio is $149 . The full version without upgrading from giga sampler is $699[ I guess thats retail] . Also you probably have heard that it will have real time effects and will record and play back multrack digital audio in one intergrated enviroment. Sounds groovey
