Fine Adjust Parameter
You can add slight detuning to the pitch with the fine adjust parameters. Notice that there
are actually two fine 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 specifically pitch, we'll move on for now, as the Hz parameter applies only to
pitch-related functions. See
of Hz.
Hard-wired Parameters
Key Tracking
This is a quick way to get additional control based on the MIDI note number of each note
you trigger. Key tracking applies a different 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 effect on Middle
C. If you set a nonzero value for key tracking, the effect 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 SE) will play a normal
C 4. Triggering C
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 PITCH page works in conjunction with the key
tracking parameter on the KEYMAP page. This is why you can set the KeyTrk parameter on
the PITCH 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. This 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.
Programmable Parameters
Source 1 (Src1)
This parameter takes its value from a long list of control sources including every MIDI
control number, a host of LFOs, ASRs, envelopes and other programmable sources.
