Remember that the parameters on the control-input pages are cumulative—they can add to
or subtract from the eects of the other parameters on the page, depending on their values.
For example, even if you’ve adjusted the pitch of a sample so high that it pins, the eects of
the other parameters may bring the pitch back down to a workable range.
Fine Adjust Parameter
You can add slight detuning to the pitch with the ne adjust parameters. Notice that there
are actually two ne adjust parameters for the Pitch function: one that changes the pitch
in cents (100ths of a semitone), and one that changes it according to its frequency (in
increments of Hertz—cycles per second). Since we’re discussing the universal control sources
here, and not specically pitch, we’ll move on for now, as the Hz parameter applies only to
pitch-related functions.
Hard-wired Parameters
Key Tracking
is is a quick way to get additional control based on the MIDI note number of each note
you trigger. Key tracking applies a dierent control signal value for each note number. In
the case of pitch, key tracking enables you to change the tuning of each note relative to its
normal pitch.
Middle C is the zero point. Regardless of the key tracking value, there is no eect on Middle
C. If you set a nonzero value for key tracking, the eect increases for each note above or
below Middle C. In the case of pitch, for example, say you assign a value of 5 cents per key
for the key tracking parameter. Triggering Middle C (C 4 on the Forte) will play a normal C
4. Triggering C
#
4 will play a note 5 cents higher than C
#
4. Triggering D 4 will play a note
10 cents higher than D 4, and so on. Notes below Middle C will be tuned lower than their
normal pitches. If you set a negative value for key tracking, notes above Middle C will be
tuned lower than their normal pitches.
Keep in mind that key tracking on the DSPCTL page works in conjunction with the key
tracking parameter on the KEYMAP page. is is why you can set the KeyTrk parameter on
the DSPCTL page to 0ct/key, and notes still increase in pitch by 100 cents/key as you go up
the keyboard. It’s because the KeyTrk parameter on the KEYMAP page is already set at 100
cents per key.
Velocity Tracking
A positive value for velocity tracking will raise the pitch as you trigger notes with higher
attack velocities. is is great for getting a trace of detuning based on your attack velocity,
especially in drum programs, where you can make the pitch of the drum samples rise slightly
with higher-velocity Note Ons, just as drums do when you strike them harder. Negative
values will lower the pitch as you increase the attack velocity.
