Extended Keyboard Techniques: Velocity | 11
Turn the rst (upper) attenuator knob to noon. The KB VEL OUT sends a voltage from
0 to 5 volts depending on how hard the keyboard keys are pressed. With the attenuator
knob at noon, a low voltage from KB VEL OUT caused by pressing the keys very softly
will raise the attenuator knob slightly – resulting in very subtle lter movement. Pressing
the keys harder will send a higher voltage out of KB VEL OUT, subsequently opening the
attenuator more and generating wider lter movement.
Take a moment to pause here and just play the keyboard – listening to how your
keyboard playing opens and closes the modulation. With some thoughtful patching
we’ve taken our initialized patch—a nice, but rather standard synthesizer sound—and
created a synthesizer that responds to our touch to generate some interesting stereo
movement.
