The Program Tree Structure - Steinberg HALION4 Mode D'emploi

Zones
A zone is the element on the lowest level in the tree structure. The zones are the
elements creating the sounds in HALion.
You can choose between synth and sample zones. These zone types differ in their
basic sound source. While a synth zone provides an oscillator section with three main
oscillators, a sub oscillator, a noise generator, and a ring modulation stage, the sample
zone loads a specific sample instead.
Busses
Busses allow you to set up the audio routing in HALion and add audio effects.
MIDI Modules
MIDI Modules can be added for programs and layers, see
page 40.
Audio Effects
Audio effects can be added for busses. For a detailed description of the available
audio effects, see the chapter

The Program Tree Structure

The Program Tree represents the signal flow inside the program from top to bottom:
The MIDI comes in at the top and goes down through the layers and MIDI modules.
The processing order of the MIDI modules inside the program or layers is from top to
bottom.
The audio is output via busses that can have any number of FX modules. The
processing order of the FX modules inside the busses is also from top to bottom.
Number of Selected Zones
Below the Program Tree, there are three numbers that indicate the following:
• The first number indicates the number of selected zones.
• The second number indicates the number of zones contained in the focused layer.
• The third number indicates the total number of zones in the program.
The three numbers are particularly useful while editing or deleting zones. For example,
if you have a piano that was recorded with several velocity layers per note, you will
know that each velocity layer has 88 sample zones. Let's say, you want to edit or
delete a whole velocity layer. With a look at the three numbers you will know if you
selected the right amount of sample zones before you edit or delete them.
The Color Scheme
To indicate additional information, the icons of the program, layers, and zones change
their color.
Icon Color
Light blue
Red
"Effects Reference"
Description
This is the standard color for zones. For sample zones this color
means all samples were found and loaded without problems.
The icon turns red if a sample zone cannot find its sample, for
example, because a removable hard drive is not connected.
