This switch selects which of the three sounds will be edited by the Level and Tune knobs.
Claves Section
NOTE: Each of the three sounds has it's own individual MIDI Controller information so when
recording via MIDI always check that this switch is pointing to the sound you want to
change. When playing back via MIDI, the position of this switch is irrelevant. i.e all the controls for these sounds can be
manipulated simultaneously via MIDI - see the 'Controller Map' section on page 42.
