The Velocity Map Editor
The top line of the display gives you the usual reminder of your location. The bottom line labels
the soft buttons, which execute the normal librarian functions of naming, saving, or deleting
velocity maps, or dumping them via SysEx. The values you see in this diagram are the settings
for the velocity map 1 Linear.
The eight parameters on the Velocity Map Editor page are expressed in terms of the eight
dynamic levels of standard musical notation. As far as the velocity maps are concerned, the
dynamic levels represented by the parameter names are simply reference points—for example,
when using the map 1 Linear, an attack velocity value of 63 will result in a remapped velocity
value at the mp level of the K2661's dynamic range.
The values for these parameters are expressed in "vels," which correspond to the standard MIDI
attack velocity values of 1–127. The values you set for each parameter determine the velocity
value that must be generated to achieve the dynamic level for that parameter. For example, if
you're using the map 1 Linear as the value for the VelocityMap parameter, then the K2661 will
play notes at full volume only when the attack velocity values for those notes are 127. Notes
with attack velocities from 1 to 15 will be played at the lowest volumes. They wouldn't all play
at the same volume; their volumes would be graduated, but would be at the low end of the scale.
The values for these parameters have another function as well. They determine the velocity
thresholds for the velocity triggers (VTRIG), as well as the velocity crossovers for multi-velocity
keymaps. Once again using the example of the map 1 Linear, if you have the VelCrossover
parameter in the Keymap Editor set to a value of mp, then attack velocity values higher than 63
will trigger the high-velocity range of a dual-velocity keymap, while velocity values of 63 or
lower will trigger the low-velocity range.
The curve that represents the velocity map is shown in the center of the page. Think of this curve
as a plot on a graph, as shown in the diagram below. The horizontal axis gives the attack
velocity values received by the velocity map. The vertical axis gives the approximate dynamic
level at which the K2661 will play the note (in response to the remapped velocity value).
