change the Pitch coarse nob (already in semitones) to what you want, accept, THEN drag the 'copy sample' button (see pic) into the playlist or back into the channel settings wave display. If you really want to do it in Edison, load the sample, click the wrench, then go to Time stretch/pitch shift. Then you can experiment with the Stretching method to see which one sounds the best. Doing it this way will not change the tempo of the sample at all, and I think that's what you want.
You would either adjust the nob to -500 or +700. So say the key of the sample is C originally, and you want to change it to G.
1.) just drag the sample into the playlistĢ.) then go to the channel settings (in the step sequencer) > Time stretching > Pitchģ.) change the pitch nob to whatever key you want (each 100 cents is equal to a semitone)
