The illustration below shows the structure and interrelationship of the Voices, Performances, and Multis.
Keyboard Mega Voices
Normal Voices use velocity switching to make the sound quality and/or level of a Voice change according to how strongly or softly you
play it.
This makes the Voices sound authentic and natural. However, with Keyboard Mega Voices, each velocity range (the measure of your
playing strength) has a completely different sound. For example, a guitar Voice includes the sounds of various performance techniques.
In conventional instruments, different Voices having those sounds would be called up via MIDI and played in combination to achieve the
desired effect.
Now with Keyboard Mega Voices, a convincing guitar Part can be played with just a single Voice, using specific velocity values to play
the desired sounds.
n The Keyboard Mega Voice names are indicated as “Mega **” in the display.
