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 ÒVeloÓ or the letter
ÒVÓ 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 (ÒBrtRhdsVelÓ is made up of ÒBrtRhdsHrdÓ and ÒBrtRhdsSftÓ) 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 Ò1 of 3,Ó sound 2 would use curve
Ò2 of 3Ó while sound 3 would use Ò3 of 3Ó).

At +00, aftertouch has no effect on the litude. 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 higher the number (either positive or negative), the greater the effect for a given
amount of aftertouch.
Tip: Use aftertouch to ÒswellÓ the amplitude of brass and horn parts.
