One shots length 16 levels

Does someone know how "in 16 level mode tuning"how to keep the sample duration the same length as the original(pad 4).Because the higher the note gets the shorter the sample length and the lower the note gets the longer length the sample gets!!!!

Have you tried warping the sample before you 16 tune it? Sound quality may suffer, but the sample should stay the same length.

Otherwise that's how standard tuning works, it speeds up/slows down the sample.
