A tone’s quality and volume
sounds slightly different
depending where it is played on
the keyboard.
This is an unavoidable result of the digital sampling process,* and does not
indicate malfunction.
* Multiple digital samples are taken for the low range, middle range, and high
range of the original musical instrument. Because of this, there may be a very
slight difference in tonal quality and volume between sample ranges.
