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.

Types of actions
Actions are used in expression maps to determine how individual switches are controlled in
order to trigger the required playback technique or combination of playback techniques. Dorico
Elements supports multiple types of actions, as different sound libraries require different actions.
Control change actions
Control change actions use MIDI CC events to modulate sounds. They are particularly
useful when using sound libraries whose sounds can be manipulated incrementally,
such as increasing/decreasing the string vibrato intensity.
Program change actions
Program change actions use MIDI PC events to switch to different sounds. They are
particularly useful when using sound libraries, such as General MIDI, that use separate
programs for each playback technique or combinations of instrument sounds and
effects presets.
Key switch actions
Key switch actions use MIDI note events to switch to different sounds. They are
particularly useful when recording MIDI live, as you can press the specied notes on a
MIDI keyboard to trigger key switch actions while simultaneously playing the notes you
want to record. Usually, key switch actions are mapped to notes in the lowest octave of
the MIDI keyboard as they are rarely used for note input.
Key switch actions are also known as “note events”.
Absolute channel change actions
Absolute channel change actions switch to a specic, explicitly numbered channel.
They are particularly useful for sound libraries that have separate plug-in instances for
each individual instrument. For example, you might use an absolute channel change
action to switch from
“natural” on channel 1 to “pizzicato” on channel 2 in your viola
section plug-in instance.
Relative channel change actions
Relative channel change actions switch to a channel numbered relative to the starting
channel. They are particularly useful for sound libraries that have multiple instruments
with separate playback technique channels in the same plug-in instance, as they can
switch between playback techniques according to their relative channel number rather
than an absolute number. For example, if you have four trumpet instruments loaded in
the same plug-in instance, each with three channels for different playback techniques,
