The KEYBOARD SENSE section contains the controls for enabling and disabling the Velocity
and/or the Aftertouch. You can use the Velocity, meaning the dynamic applied to the keyboard
keys, to control up to 19 sound generation parameters (see point 8.9), while the Aftertouch,
meaning the force applied to the key after it has been depressed, can be used to regulate up to
14 generation parameters (see point 8.9).
The relative front panel section is as follows:
VELOCITY: enables (LED illuminates) or disables (LED off)
use of the note velocity to control generation parameters,
which can be assigned using the CONTROLLERS section of
the EDIT TIMBRE display menu (point 8.9).
AFTERTOUCH: enables (LED illuminates) or disables (LED off) use of the Aftertouch to
control generation parameters, which can be assigned using the CONTROLLERS section of
the EDIT TIMBRE display menu (point 8.9).
The Ribbon Controller allows the user to modify two generation parameters simultaneously by
simply placing a finger on and/or moving it over its surface. This allows you to modify the tone as
if you were using the knobs on the front panel.
The OB-12 Ribbon Controller is illustrated below:
To assign the parameters you wish to control using this device, use the EDIT CONTROLLERS
display menu (point 8.9).
As you can see, as well as the Ribbon Controller there are also two buttons close to it, as follows:
[RELATIVE]: when this function is active, the Ribbon Controller "neutral" position (the position
which does not produce any variation of the sound, or the central position for controls with
positive and negative values and the far left position for controls with positive values only) is
assumed on the basis of where the control surface is first touched.
[HOLD]: when this function is selected, each variation of the parameter (or parameters)
assigned to the Ribbon Controller will be maintained even after the finger is removed from the
control surface.
