While Tascam \"bought\" Nemesys, Steinberg seems to have come behind how to do the disk streaming thing. At least it is said to be able to do what Giga does, according to a German music magazine (they have a test of HALION).
I wouldn\'t worry so much about Halion and other software samplers, cos as low as the prizes are for all these - including the giga-x, we will probably have more than one software sampler - just as we used to have more than one synth. You can use these products in different areas, where thay are strongest. It is not \"one or the other\"
