E-21Basic OperationsA number of the tones that are available with this keyboardhave been recorded and processed using a technique calleddigital sampling. To ensure a high level of tonal quality,samples are taken in the low, mid, and high ranges and thencombined to provide you with sounds that are amazinglyclose to the originals. You may notice very slight differencesin volume or sound quality for some tones when you playthem at different positions on the keyboard. This is anunavoidable result of multiple sampling, and it is not a signof malfunction.This keyboard has only a single DSP sound source. Because ofthis, selecting tones for which DSP is enabled for multipleparts when layering or splitting tones (page E-66, 67) cancause conflicts. To avoid conflicts, DSP is allocated to the lastDSP enabled tone, and DSP is disabled (DSP line OFF) for allother parts.DSP line is a parameter that controls whether or not thecurrently selected DSP effect is applied to a part.* Each tonehas a DSP line parameter. Selecting a tone for a part appliesthe tone’s DSP line parameter setting to all parts.* The DSP line parameter is turned on (DSP effect isapplied) for the 300 Advanced Tones numbered 000through 299, and turned off (DSP effect not applied) forthe 200 preset tones from 300 to 499.
