PRESSR — Pressure (After-touch)
Pressure, also called after-touch, is a modulator that varies a manual level within a voice
depending on how hard you press down on a key or keys.
When playing the KT keyboard, after you have struck a key, and while the note is sustaining,
continuing to press down harder on the key brings in the pressure modulation.
Pressure comes in two varieties — Poly-Key™ pressure (or Polyphonic pressure), which affects
each note individually, and Channel pressure (or Mono pressure) which affects all notes that are
playing when you exert pressure on any key. Both types are received via MIDI on the KT,
however, the KT keyboard can only generate channel pressure.
Not all sounds are programmed to respond to pressure (like piano sounds). If pressure seems to
have no effect when you play certain sounds, it is likely that pressure is not assigned as a
modulator anywhere within the sound.
The effect of pressure as a modulator is positive-going only, though assigning a negative
modulation depth will cause increased pressure to reduce manual levels.
KEYBD — Keyboard Tracking
This uses the position of a note on the keyboard as a modulator:
+100
+50
0
-50
-100
KT-88 keyboard
MIDI Note numbers 0-127
KT-76 keyboard
As the above illustration shows, the effect of KEYBD as a modulator goes negative as well as
positive. The effect of KEYBD is to reduce the manual level on notes below the break point (F#
above Middle C, F4+, MIDI Note #66), and increase the manual level on notes above the break
point. Negative modulation amounts will do the opposite.
VELOC — Velocity
Velocity means how hard you strike a key. Selecting VELOC as a Modulator allows you to
modulate any manual level with velocity. Velocity as a modulation source only goes positive
(though assigning a negative modulation amount will make the level reduce with increased
velocity).
