Surface Mapping and Direct Assign in HUI
One of the most powerful features of EUCON Control Surfaces is the ability to map any DAW channel to any Surface Strip. This
is called Direct Assign. When using HUI mode it is important to remember the relationship between the Surface, the HUI layer
and Pro Tools.
It is possible to map HUI Strips to the surface in the same fashion as EUCON applications. The difference, however, is that only
the HUI Strips are mapped, and not the actual Pro Tools channels. This means that once HUI Strips are mapped, the HUI layer
can “move” underneath (by Banking or Nudging), and the Pro Tools tracks as they appear on the surface will change accordingly.
For example: say you open your Pro Tools session and have 2 HUI modules assigned. By default, channels 1-16 are assigned to
HUI Strips 1-16 and then onto Surface Strips 1-16 respectively. You proceed to Direct Assign HUI Strips 5-8 onto the 4 MC Control
faders (or MC Pro fader unit). When you HUI Bank, the HUI Layer “moves” to the right by 16 channels (2 banks). Pro Tools chan-
nels 17-32 are now assigned to HUI Strips 1-16, and the 4 Surface Strips assigned earlier now display Pro Tools channels 21-24
(5+16=21 and 8+16=24). The Surface Mapping did not change; the HUI layer simply moved, passing on a different set of Pro Tools
channels to the surface through the HUI layer.
In the image above, you can see that Surface Mapping takes place between the HUI layer and the Surface Strips. HUI Strips are that
are mapped to the Surface simply pass on the track data from the assigned channel in Pro Tools.
Storing Layouts
It is currently not possible to store Layouts as part of a Pro Tools session. EUCON-aware applications have this added benefit
which enables this data to be stored with the session / project files. Using Pro Tools markers with Show / Hide track data can
achieve similar results. These can also be recalled from the surface using Soft Keys.
