Sample Zones and their Root Keys

The root key determines the original pitch of a zone, that is, 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 multi-sampled programs contain samples of a specific instrument, usually containing only one sample zone per key on the keyboard. The single-shot programs contain different sample zones that are mapped across the keyboard, without relationship between key and pitch. For these programs, you might want to move sample zones. After moving the zones, adjust the root key to make the zones play back at the correct pitch.

  • To set the root key, enter the value in the Root Key value field, or hold down Alt and click the corresponding key on the keyboard.
