DSP Functions

Once you've entered the Sample Editor, press the DSP soft button to gain access to the DSP
functions. The DSP function parameter will be highlighted, allowing you to scroll through the
list of functions with the Alpha Wheel or Plus/Minus buttons.
Remember that the DSP functions operate only on RAM samples. You'll notice that if you're
editing a ROM sample, there is no DSP soft button; instead, there's an extra Link soft button
for your convenience.

With the Normalize function, you can rescale the amplitude of the selected sample segment to
optimize its level relative to other samples. The Normalize function will uniformly boost the
amplitude of the current sample range as high as possible without clipping, stopping just
before the loudest element of the sample would be clipped. You might want to use the Volume
Adjust function to boost the current segment manually, but the Normalize function does it
automatically, and prevents you from boosting the amplitude too much.

The Truncate function will automatically reset the Start (S) and End (E) points of the sample.
This can be quicker than trimming the sample manually on the TRIM page.
Use the Start and End parameters to select a specific sample range. Set the Thresh parameter
from -96 to 0dB to set the noise floor. When you press the Go soft button, the K2500 will search
inward from the start and end points you set, until it finds the first sample that exceeds the
noise floor. Everything outside the range will be left out. You'll want to experiment with
different thresholds to find the noise floor that suits each sample you truncate. If the new End
point is inside the current loop point, the loop will be disabled.
When you press the Go soft button, you'll be prompted "Keep this change?" Unlike the other
DSP functions, answering Yes does not bring up the Save dialog. It registers the new Start and
