Additional Parameters - Kurzweil K2600 Musician's Manual

parameters, itÕs a good idea to start with all of them set to 0 (or the value that minimizes their
effects), then adjust them one by one. This will help you understand exactly what effect each
parameter has, and will give you an idea of the variety of effects each parameter can produce.
Then you can start combining the effects of multiple parameters, and quite possibly take your
sound in a whole new direction. YouÕll quickly become familiar with the control-input pages for
the DSP functions, since most of them contain the same parameters, with just a few variations.
YouÕll Þnd that they all look much alike. The top line of each page, however, will indicate which
DSP control input it represents (PITCH, or F1ÐF4).
For example, on the page below, the top line tells you that the currently selected DSP function is
the high-frequency stimulatorÑits name is abbreviated and enclosed in parentheses. You can
also see that youÕre looking at F1, which in this case controls the frequency of the high-frequency
stimulator. So the top line of these pages always shows three things:
1. The currently selected control input (PITCH or F1ÐF4);
2. The aspect of the current DSP function controlled by the input (this varies depending on
the current DSP function);
3. The currently selected DSP function (usually abbreviated, and in parentheses). Items
1 and 2 match the label of the soft buttons that select each page. The page below, for
example, is selected with the soft button labeled F1 FRQ

Additional Parameters

In addition to the common DSP control parameters youÕll Þnd on each page, youÕll also see a
few others on various pages. TheyÕre described here, since programming them is the same
regardless of the page on which they appear. Depending on the DSP function they affect, theyÕll
have different ranges of values and different units of measurement (%, dB, etc.).
Pad
Many of the DSP functions boost the signal as it passes through. Depending on the signalÕs
input level and the amount of gain (boost) introduced by any given DSP function, its output
may clip, which will alter the sound considerably. Clipping may also occur as a result of phase
shifting, but this is not as common as clipping caused by gain. While you may Þnd clipping to
be a useful component of some sounds, youÕll want to remove it from others. The Pad
parameter, which appears on the control-input pages of many DSP functions, lets you attenuate
(reduce the amplitude of) the signal by 6, 12, or 18 dB at the input of those functions. Use the
Pad parameter to reduce or eliminate any undesired clipping caused by the currently selected
DSP function.
