The Root Key

The root key determines the original pitch of a zone. In other words, it defines the key
on which the zone is played without being transposed. Samples can contain root key
information embedded in the sample file. When they are loaded, they are automatically
mapped to the corresponding keys.
The sample collections included with HALion contain both multi-sampled instrument
programs and single-shot sample programs. The former contains samples of a specific
instrument (usually containing only one sample zone per key on the keyboard). The latter
contain different sample zones that are mapped across the keyboard, without any
relationship between key and pitch. For multi-sampled instrument programs, there is no
need to change the root key settings, but for single-shot sample programs, you might
want to move sample zones.
If you have moved sample zones in the Mapping editor, you can make them play back
at the original pitch by setting the root key.
You have the following possibilities:
• Directly enter the value in the Root Key value field.
• Hold [Alt]/[Option] and click the corresponding key on the Mapping editor
keyboard.
• You can make the root key move with a zone by holding [Ctrl]/[Command]-
[Alt]/[Option] while dragging or by activating "Move Root Key with Zones" on the
toolbar.
You can also adjust the root keys of the selected zones without changing their key or
velocity ranges using one of the options on the "Set Root Key" submenu of the zone
context menu.
The following options are available:
Option
Center of Zone
High Key of Zone
Low Key of Zone
Key Text in Sample Name
Key Number in Sample
Name
Root Key in Sample File

Triggering Zones

You can trigger zones in the Mapping editor. To activate trigger mode, click the
Trigger Zones button on the toolbar.
