Create a folder where all your samples will be stored. For a start put there any wav file. Now. You might want to check the result of mapping on the fly so in the audiomixer(NUM8) turn EXS24 as a first audioinstrument(audioinst1) and be sure to select it in the Arrange window as well. Now go to *Audio>>EXS24 Instrument Editor. The mapping editor will appear. Further steps: *Instrument>>New You may save it and select it with +/- in the EXS24. *Zone>>New Zone Now put your wav into new zone by simply clicking on the dialog box. Set range where you want your sample to be on the keyboard. Select key note as it shows where the original note is. Save and voila! the rest is just a case of experiment. sorry for my bad English best regards
