Precise detection of key acceleration enables expressive
play and control of dynamics for each note. The VARIO
system works with optical sensors, that means contact-
free and therefore without any influence on the playing
experience. The highly sensitive electronics detect even
the smallest movements and changes in the distance
between the sensor surface and the key above it.
Just like your acoustic instrument during tuning,
intonation and maintenance, this part of the digital
system therefore occasionally requires a little attention.
We recommend that you calibrate the keys as part of the
initial setup, for example after transporting and setting
up the instrument. But don’t worry: in combination with a
small number of parameters (see the sections “Adjusting
the keystroke” and “Sensitivity curve”), even novice users
can optimally adjust their VARIO system.
It’s that simple:
Go to the “Calibration Keys” section.
• Press Start - the keyboard in the graphic will be
colored.
• Now play one key at a time and “uncolor” the
keyboard-graphic in this way.
• Ready? Then please press Save to finish.
Hints:
• Play as normal but without special “expression”
(Staccato ... Legato ... Forte-Fortissimo ... Repetition,
etc.). So the best thing to do is just as if you were
practicing a simple scale.
• It is only important that you move the keys from
the rest position to their lowest point - but without
“squeezing them into the felt”.
• The order does not matter. It is also possible to press
a key several times, perhaps if you have slipped from
a key or if you have only partially hit a key.
The next step is to adjust the keystroke, which is used to
calculate the velocity (see next section).
