Touch Curve
As with an acoustic piano, the CA98/CA78 digital piano produces a louder sound when the keys are struck with
force, and a softer sound when the keys are played gently. The volume and tonal character change in relation to the
strength and velocity of playing – on a digital piano this system is referred to as ‘touch sensitivity’.
The Touch Curve setting allows the touch sensitivity of the keyboard to be conveniently adjusted. There are six
different preset touch curve settings available, with an additional ‘User’ setting allowing performers to customise
the instrument’s keyboard responsiveness to suit their individual playing style.
The default ‘Normal’ setting is designed to accurately recreate the touch of a Kawai concert grand piano. However,
if the keyboard feels too light, or fortissimo playing is achieved too easily, it may be desirable to select a heavier
touch curve. Alternatively, if the keyboard feels too heavy, or fortissimo playing is too difficult to achieve, it may be
desirable to select a lighter touch curve.
* This Virtual T
echnician setting will affect all sounds.
Touch Curve types
Touch Curve
Description
Light +
Requires less striking force to achieve a forte note. For players with a very delicate touch.
Light
A louder volume is produced even when playing with a soft touch. For those still developing finger strength.
* This touch curve is recommended for children and organ players.
Normal
(default)
Reproduces the standard touch sensitivity of an acoustic piano.
Heavy
Requires a heavier touch to produce a loud volume. Ideally suited to those with stronger fingers.
Heavy +
Requires considerably more striking force to achieve a loud volume.
Off (constant)
A constant volume is produced regardless of how hard the keys are struck.
* This touch curve intended for playing sounds of instruments that have a fixed dynamic range (e.g. organ and harpsichord).
