Sorry ... I might have missed this one before.

This is normal .... and here is why.

In conforming with the natural response (playable range etc) of each instrument, Ketron only samples as high and as low as the actual instrument will actually go. This means that in some instruments, you won't hear notes on all 88 keys. In such a case, the natural nausance/noise/effects of the instrument are assigned to keys above and below the instrument's sampled range. So in the case of the Nylon, you will get body taps (a person tapping the body of the guitar), fret sounds (running up and down the guiar neck as you change closed chords) ... etc all assigned to these high and low keys.

Again - normal operation.

Thanks,

AJ
