The Transpose Menu; The Velocity Menu - Kurzweil PC2KBD Musician's Manual

Descriptions of Parameters
Setup Editor Parameters
AutoSplit Key
When the value of the AutoSplit parameter is On, this parameter sets the split point for all zones
in the setup, overriding each zoneÕs key range settings. Depending on the key ranges youÕve set
for the zones in any particular setup, this may not be useful. On the other hand, you may enjoy
the ßexibility it provides for muting and soloing. See The AutoSplit Feature on page 3-20 for more
information.
When the value of AutoSplit is Off, the value of AutoSplit Key appears in parentheses,
indicating that itÕs inactive. In this case, the setup uses the values of the Low and Hi parameters
to determine the key ranges of each zone.

The Transpose Menu

Transposition
Sets the amount of transposition for the current zone. In the default setup, thereÕs no
transposition on any of the zones. Intuitive entry is handy for editing this parameter. ThereÕs an
example on page 4-5 that describes how it works.

The Velocity Menu

The parameters in this menu control the PC2Õs response to the attack velocity of the notes you
playÑin other words, how hard you strike the keys. The settings for the velocity parameters
affect both the PC2Õs sounds, and the MIDI information the PC2 transmits via its MIDI Out port.
A Bit of Background
When you strike a key, the PC2 generates a Note On message with an attack-velocity value
corresponding to how hard you strike the key. Attack-velocity values range from 1 to 127; they
never go lower than 1 or higher than 127. A value of 1 is the softest and 127 is the loudest.
The velocity parameters interact extensively with each other, so changing one parameterÕs value
can alter the way that others affect the PC2Õs velocity response. WeÕll give you a few examples of
this interaction. More to the point, itÕs quite complicated to describe all the possible ways you
can use these parameters in combination with each other. As we describe each parameter, the
description assumes that all the other parameters are at their default values. Experimenting with
different combinations is the best way to understand how these parameters interact.
You can use the velocity parameters in several interesting ways: customizing the keyboard for
your playing style; compensating for velocity-response differences in instruments receiving
MIDI from the PC2; triggering different sounds as you play softer or harder (see Velocity
Switching on page 4-19 to learn how to trigger different sounds at different velocities).
To illustrate how the velocity parameters work, weÕve included a number of graphs with the
parameter descriptions. In each graph, the horizontal axis (labeled Keystrike Velocity)
represents how hard you play. The vertical axis (labeled Final Attack-Velocity Value) is the
attack-velocity value that gets sent to the PC2 to and to the MIDI Out port after any adjustments
resulting from non-default values for the velocity parameters. The lines in the graph are the
velocity curveÑwhich shows the relationship between every possible keystrike velocity value
and the resulting Þnal attack-velocity value.
