Host based DAW

[Michal Jurewicz]

Thanks, I was following your postings. I wrote the paper in spring, and a
lot the figures were based also on tests reported here, prior to your posts.

As for BeOS support, we had at our booth at the AES Show a double pentium
BEOS machine running freshly received Nuendo beta for BeOS. This is the
same software that was just released on Win NT  and it's the most advanced
audio app for BeOS I've seen. On BeOS it really rocks. Fast , responsive,
many channels, 2496, surround sound , plug-ins etc, in other words first
real commercial app. It may become a vehicle for more.
