Amplifier Section

The Amplifier section has two tabs: Main and AUX. The Main tab gives you access to the level and pan settings of the zone. The AUX tab allows you to send the zone to the four global AUX busses and to route the zone to one of the plug-in output busses.

Main Tab

Level

Specifies the loudness of the zone.

Headroom

Specifies 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

If this button is activated, incoming MIDI expression controller and controller #7 data is used to calculate the voice amplitude. This ensures a correct behavior when working with General MIDI files, for example.

Level Key Follow

Allows you to control the volume depending on the note pitch. Positive values mean that, the higher the notes you play, the more the volume is raised. With negative values, higher notes result in lower volume.

Center Key

Specifies the MIDI note that is used as the center position for Level Key Follow.

Pan

Determines the position of the 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 loudness variations across the stereo panorama.

  • If this parameter is set to 0 dB, it 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.

  • With this parameter set to -3 dB, the option uses the cosine/sine pan law.

    The loudness is cut by -3 dB at the center position, but the energy is preserved when moving the source signal across the stereo panorama. The -3 dB option sounds more natural. The transition from hard left to hard right sounds much smoother than with the 0 dB or the -6 dB setting.

  • With this parameter set to -6 dB, this option uses the linear pan law.

    The loudness is cut by -6 dB at the center position, and the energy is not preserved when moving the source signal across the stereo panorama. The -6 dB option sounds more synthetic. The transition from hard left to hard right sounds more abrupt than with the -3 dB setting.

  • With this parameter set to Off, no panning is applied.

Random Pan

Allows you to offset the pan position randomly with each played note. Higher values cause stronger variations. At a setting of 100%, the random offsets can vary from fully left to fully right.

Alternate Pan

Allows you to alternate the pan position each time that you play a note. To start panning on the left, use negative values. Use positive values to begin on the right. At a setting of +100%, the first note plays hard right, the second note hard left, and so on.

Reset

The initial pan position is set once, on startup. Subsequently, each note that you play is counted to determine the next pan position. To reset this counter, click the Reset button.

Pan Key Follow

Allows you to adjust the pan modulation via the MIDI note number. Set this parameter to positive values to offset the pan position towards the right for notes above, and towards the left for notes below the center key. Use negative values to offset the pan position towards the left for notes above, and towards the right for notes below the center key.

At the maximum setting of +200%, the pan position moves from hard left to hard right within two octaves: Fully left is reached one octave below, and fully right is reached one octave above the center key.

Center Key

Specifies the MIDI note that is used as the center position for Pan Key Follow.

AUX Tab

AUX 1-4

If you send the zone signal to one of the local AUX busses, you can control the signal level that is sent to the busses via the controls AUX 1-4.

Output

Zones can be routed to one of the following destinations:

  • Busses that are higher up in the hierarchy of the program.

    This includes the plug-in outputs, but not the bus that is set for the program slot or global AUX busses.

  • Busses that are part of the same layer and that have been inserted after this zone or bus.

If you route a zone directly to one of the output busses, it does not pass through the layer, program, and slot busses.
