Mixing, Routing, and Effect Handling
Audio Bus Architecture
207
Apart from the routing and mixing possibilities, audio busses allow you to load insert effects
for processing audio on that bus. Depending on how you set up the audio busses, you can
load insert effects on single layers, the whole program, or the slot. For example, you can
process only the strings of a piano and strings layer sound with a chorus effect, and keep the
piano unprocessed. You load insert effects into the effect slots of the channels in the Mixer.
In addition, audio busses allow you to route audio via sends to an AUX bus. This way, you
can set up send effects which can be shared among the layers, programs, and slots. You
assign sends directly in the zones or with the effect slots of the channels in the Mixer. You
can adjust the level for the sends, which allows you to control the amount of the effect that is
loaded on the AUX bus.
AUX Busses
You need an AUX bus to route individual audio signals from zones or audio busses
to AUX effects. HALion provides 4 global AUX busses and 4 local AUX busses that
you can add for individual layers. By default, the output of an AUX bus is routed to
the master output bus, but you can reassign its output to other output busses.
•
To set up an AUX effect, load an insert effect into one of the effect slots of
the AUX bus.
•
To hear the effect, raise the send level of a zone, route the output of a zone
or your audio bus to the AUX bus, or set up a send in the effect rack of your
audio bus.
The send levels control the amount of the effect that is loaded into the AUX bus.
You can set up sends for each zone and audio bus separately.
Master Effect Bus
The master bus works similar to the AUX busses. The only difference is that the
master bus has no bus output selector, because it is hard-wired to the main plug-
in output (1/2).
Multi-Channel Effects
HALion comes with a large number of effects that are mainly intended for use on
stereo busses. However, most of them can also be used on surround busses. In
this case, the effect is processed on all channels. If a bus changes from stereo to
surround, the effect follows. For effects with level meters, the number of meters
is adapted accordingly.
Zones
The outputs of zones are routed to the first audio bus of the next higher layer or
the program. You can reassign the outputs of the zones to any master output.
Layers
To save processing power, audio busses for layers are optional. You can create
them at any time in the Program Tree. By default, audio busses of layers are
routed to the first audio bus of the next higher layer or the program. You can
reassign the outputs of the audio busses of the layers to any master output.
Programs
By default, audio busses of programs are routed to the audio bus of the slot into
which the program is loaded. You can create additional audio busses. You can
reassign the outputs of the audio busses of the program to any master output.
