Vista 1 Digital Mixing System
7-4 DAW Control
When controlling the DAW via HUI, an auto-label mechanism copies the
channel labels of the workstation project from the DAW channel strip to the
Vista console. If the DAW should not support HUI (see list above), user labels
can be manually entered in the strip setup now for every DAW channel.
Note Only one DAW can be controlled at a time. The Mackie protocols support
a maximum of 32 channels, so this is also the maximum number of DAW
channels that can be controlled.
