Click is heard when you press/
release a key
On a tone wheel organ, a slight
“blip” noise is heard when you press
or release a key. Initially, this was
considered a defect, but as organs
with this characteristic came to be
used in a wide range of music, it
grew to be considered part of the
sound. The VK-88 faithfully
simulates this key click noise, which
is characteristic of tone wheel
organs.
Turn the [KEY CLICK] knob to
adjust the key click level.
The volume of the click can be
adjusted with “ON CLICK LEVEL”
and “OFF CLICK LEVEL.”
