YouÕll recognize the common DSP control parameters, along with several other parameters.
Keep in mind that thereÕs a set of common control parameters for each of the DSP functions; in
this case weÕre describing them only as they apply to the pitch control function.

Coarse Adjust

The Adjust parameter (sometimes coarse and Þne adjust) is the Þxed amount of adjustment you
add to any DSP function. On the PITCH page, the Coarse Adjust parameter will change the
pitch in semitone increments. Use this as a starting point to set the pitch where you want it to be
normally. This will shift the pitch of the currently selected layer, and will affect the playback rate
of sampled sounds. Sampled sounds have an upper limit on pitch adjustment. ItÕs normal for
the pitches of sampled sounds to ÒpinÓ (stop getting higher) when you adjust the pitch upward
in large amounts. The oscillator waveforms can be pitched higher. Any sound can be pitched
downward without limit.
The primary use of the Adjust parameters (Coarse and Fine) is to offset the cumulative effects of
the other parameters on the control-input pages. For example, you might set a high value for
key tracking (deÞned below) for a dramatic change in effect across the keyboard. The effect
might be too much at one end of the keyboard, however, so you could use one of the Adjust
parameters to reduce the initial amount of that effect.
The K2600 always uses real values of measurement, rather than just arbitrary numbers, for
adjustable parameters. This means that you specify pitch in semitones and cents, amplitude in
dB, and Þlter cutoff frequency in Hz.
Remember that the parameters on the control-input pages are cumulativeÑthey can add to or
subtract from the effects of the other parameters on the page, depending on their values. For
example, even if youÕve adjusted the pitch of a sample so high that it pins, the effects of the other
parameters may bring the pitch back down to a workable range.

Fine Adjust

You can add slight detuning to the pitch with the Þne adjust parameter. Notice that there are
actually two Þne adjust parameters on the PITCH page: one that changes the pitch in cents
(100ths of a semitone), and one that changes it according to its frequency (in increments of
HertzÑcycles per second). Since weÕre discussing the universal control sources here, and not
speciÞcally pitch, weÕll move on for now, as the Fine Hz parameter applies only to pitch-related
functions. See The PITCH Page on page 6-27 for a more thorough description of Fine Hz.
