Types of switches

Switches are used in expression maps to trigger the required playback technique or combination of playback techniques. Dorico Elements supports multiple types of switches.

Base: A fundamental change to the playing technique or articulation, such as changing from arco to pizzicato or unmuted to muted. Base switches are mutually exclusive, meaning a new base switch replaces the previous one.
Add-on: A switch that applies in addition to the existing base switch. For example, some sound libraries allow you to use the same legato switch in addition to different base switches. Add-on switches do not remove or change base switches. Add-on switches can only trigger simple key switch notes and controller values.
Init: A switch that sends instructions when playback starts, such as ensuring a MIDI controller always starts at a set value. By default, every expression map contains an empty init switch. Init switches can only trigger simple key switch notes and controller values.
