Don\'t feel bad asking this question. I asked the same thing when I was first looking at getting a giga system. I ended up going with gigastudio and I would recommend that you do the same. I\'m not even sure if Tascam sells gigasampler anymore, but there are different levels of gigastudio to choose from.
I don\'t recomend you gigasampler because I just works with Win 9x and GigaStudio works in windows XP (not works ok for everyone) and also gigasampler can\'t read some giga Files created just for GigaStudio
