I don't understand if all channels audio are available through usb,
or just one at a time, and faders are always accessible from the pc side.
I know the Hallen and Heath Zed-i 10 has at least 4 channels available through usb
audio, which is also way more recent then the Presonus.
It looks like the Presonus is still a very good deal for production,
when you have many hardware synths that you have to mix and control in RT.
Has anyone got one that can shed some light on its usb-fw audio features?
