Bypass
The Bypass buttons in the top right of the section allow you to listen to the zone
without modulation of the filter envelope and without any filtering.
The Amplifier Section
The Amplifier section has two tabs: Main and AUX.
The Main Tab
The Main tab gives you access to the Level and Pan settings of the zone.
Level
Here, you can adjust the loudness of the zone.
Headroom
Use this parameter to specify the headroom for polyphonic playback. By default,
HALion uses a headroom of 12 dB. For monophonic programs, such as drum loops,
set the headroom to 0 dB. If you work with low polyphony values, a headroom of 6 dB
is sufficient.
Expression
When this button is activated, HALion uses incoming MIDI expression controller and
controller #7 data to calculate the voice amplitude. This ensures a correct behavior
when working with General MIDI files, for example.
• If you do not want the Expression data to be used, deactivate this button.
Key Follow
Use this parameter to control the volume depending on the note pitch. Positive values
mean that the volume is higher the higher the notes you play. With negative values, the
volume decreases the higher the notes you play.
Center Key
This parameter determines the MIDI note that is used as the central position for the
Key Follow function.
Pan
Here, you can set the position of a sound in the stereo panorama. At a setting of
-100 %, the sound is panned hard left, and at +100 %, it is panned hard right.
Mode
With this option you can specify how the loudness changes across the stereo
panorama. The following modes are available:
• 0 dB: This option works like a balance control.
Setting the pan control towards the left fades out the right channel and vice versa.
At the center position, the loudness is not cut.
