Velocity Curve (13 choices)

This selects how the sound will respond to the dynamics of your playing the keyboard. A LINEAR curve is the norm, whereby the increase in level is equal to the increase in velocity; the velocity values increase as you play harder. Many of the Velocity Curves make up sets to be used by 2, 3 or 4 sounds in order to facilitate velocity crossfading, whereby a different sound is played depending on how hard or soft the keyboard is played.

As explained earlier, many of the samples to choose from when assigning voices are already velocity switching. These samples usually have the word “Velo” or the letter “V” in their names, indicating that there is actually more than one sample per note which can be selected by how hard or soft each note is played. However, the velocity point at which these sounds change is fixed and cannot be altered. If you want to create your own velocity crossfading Program, assign the single-sample versions of the same samples (“BrtRhdsVel” is made up of “BrtRhdsHrd” and “BrtRhdsSft”) to two or more sounds, then use the appropriate velocity curves for each sound (in a three-way velocity split, sound 1 would use curve “1 of 3,” sound 2 would use curve “2 of 3” while sound 3 would use “3 of 3”).

Aftertouch Depth (-99 to +99)

At +00, aftertouch has no effect on the amplitude. Applying aftertouch with this parameter set to a positive value raises the amplitude; conversely, applying aftertouch with a negative value will make the sound softer the harder you press. The
