I'm experimenting with using a combinator to play a not from an NN-XT and a synth into a vocoder. I created a little wave file with my voice saying "test test test" and uploaded that into NN-XT after initializing it. Now, for vocoding, this isn't a big deal, but I was wondering how you tell the NN-XT to time stretch your samples to compensate for the difference in playback speed as you play it with a higher note value. In other words, how do you get "test test test" to sound higher but last just as long time-wise as the original sample? Or is this even possible?
