Edit Section

Here, you find common settings of HALion and you can specify an external wave editor that you want to use for editing your samples.


The settings in this section are not saved with a project, but affect the plug-in as a whole.

Show Tooltips

If this option is activated, a tooltip is shown when you move the mouse over a control.

Show Value Tooltips

If this option is activated, parameters without a value field display their value in a tooltip when you use the corresponding control.

Auto Collapse Sections

If this option is activated and you expand a section, all other sections are automatically collapsed.

Restore Screen Set

Restores the corresponding screen set when you load a multi.


In a VST 2 or AU environment, screen sets and windows are always restored when loading a multi.

Solo Mode
  • In Standard mode, you can solo multiple programs or layers to hear them combined.

  • In Exclusive mode, only one program or layer can be soloed at a time.

HALion Sonic Edit Mode

This mode allows you to edit a HALion Sonic or HALion Sonic SE preset in HALion and then save it in its original preset format, so that it can be opened in the plug-in that it was created in.

If this mode is activated and you load a preset, all layers, busses, effects, and other modules that are required by HALion Sonic/HALion Sonic SE cannot be deleted or replaced, in order to ensure the compatibility with those program versions. However, you can modify the parameter values of these elements.

Furthermore, if you are working with layers that were created in HALion 6/HALion Sonic 3 or later, you can make structural changes within the four HALion Sonic layers, that is, you can add, remove, or replace sublayers, zones, or other modules within these layers.

To indicate that a preset is in HALion Sonic Edit Mode, the HS button in the Program Tree toolbar is activated.

Number of Undo Steps

Specifies the number of available undo steps.

High DPI Mode
  • If High DPI Mode is activated, the plug-in uses high-resolution bitmaps when it is displayed with a scaling of 150 % and higher on a high-resolution monitor, such as 4K (UHD), 5K, etc. This allows for sharper images on high-resolution displays.


    Windows systems currently only support scaling factors that are multiples of 100. For example, if you use a scaling factor of 150 %, in HALion, the scaling factor used is 200 %.

    High DPI Mode may not be compatible with some combinations of software and hardware. If you experience display issues with your setup, you can deactivate High DPI Mode.

    If High DPI Mode is deactivated, the native monitor resolution is used.

HALion Partner

When you work with a HALion Partner license, activating this option allows you to use the HALion Partner-specific features.


If you change this setting, you must reload the plug-in for the changes to take effect.

Key Commands

Opens the Key Commands dialog, where you can view and assign key commands.

Reset Messages

If you click this button, all message dialogs that have been suppressed with the Don't Show Again option are displayed again.

External Wave Editor

HALion allows you to specify an external sample editor application that can be used to perform destructive offline editing on a sample, for example applying EQs, filtering, or denoising.

Here, you specify which application to use. You can enter the path manually or click the Browse button to navigate to the corresponding application folder.

Update Sample

Specifies what happens if a sample is saved in the external wave editor.

  • If Ask is selected and you switch back to HALion from the external editor, you are asked whether you want to replace the current sample with the modified sample.

  • If Always is selected, HALion accepts the modified sample.

  • If With Backup is selected, HALion accepts the modified sample and automatically creates a backup of the old sample file.

  • If Never is selected, modified samples are never accepted automatically. You must import modified samples manually from the temp folder.

Temp Folder

Allows you to specify a temp folder for exchanging samples between HALion and the external editor.

Temp Cleanup

After a specific period of time, HALion deletes temporary sample files from the temp folder. The Temp Cleanup option allows you to make settings for this process.

  • If Ask is selected, you are prompted to confirm the cleanup of the temp folder.

  • If Always is selected, temporary files are deleted without further notice. If a file cannot be deleted, an error message is shown.

  • If Ignore Error is selected, temporary files are always removed without further notice. If a file cannot be deleted, no error message is shown.

  • If Never is selected, temporary files are never deleted automatically. You must delete them manually.
