Position Mode (PosMode)
When you touch the Ribbon, the PC3A responds in one of two ways, depending on the setting of
the PosMode parameter. Relative means that wherever you touch the Ribbon becomes the “zero
point” for whatever the Ribbon is controlling; you won’t notice any change in the sound until
you slide your nger. Relative mode tends to be the most natural for performance—just wiggle
your nger anywhere on the Ribbon to get vibrato in many factory programs and setups. You get
the same eect no matter where you do the wiggling.
Absolute means that the zero point for the Ribbon is always at exactly the same physical location
on the ribbon. By default this is the center of the Ribbon, although you can use the Center
parameter to put the zero point elsewhere. In Absolute mode, just touching the Ribbon aects the
sound (unless you touch it at exactly the zero point). Every movement you make along the
Ribbon sends control values based on how far you are from the zero point.
Spring
When Spring is On, the Controller to which you’ve assigned the Ribbon “springs” back to its
zero point automatically when you lift your nger o the ribbon. This is generally the behavior
you want.
When Spring is O, the Controller to which you’ve assigned the Ribbon sticks at its current value
when you lift your nger o the Ribbon. While this can be useful, you should be careful with it.
When Spring is O, if the Ribbon is doing something when you exit the setup, it’ll continue
doing that when you return to the setup. This can be good or bad. If you want to set Spring to O
in a setup, but want to be sure of the initial sound of the setup, go to the RIBBON page in the
setup, and for each Ribbon for which you’ve set Spring to O, set the entry value (Ent) parameter
to a value of 0 (or whatever you like).
Center
This denes the zero point for the Ribbon (or for each section on the Ribbon)—the point at which
the Controller to which the Ribbon is assigned has no eect on the sound. You can choose any
point between 0 and 127. A value of 64 puts the zero point in the physical center of the Ribbon.
Values of 0 and 127 place the zero point at the section’s extreme left and extreme right. Note that
setting the Spring parameter to O disables the Center parameter for that ribbon.
The value you choose for this parameter can have considerable eect. In many factory setups, for
example, the Ribbon aects pitch. In these setups, changing the value of the Center parameter
would transpose the setup.
