Make a wavetable sound the most like the sample

Hello All,

How can I make the imported audio sample into the OSC sound as much as possible like the original audio? I have tried a few things but seems I am missing something. I´ve assigned a LFO to the table position all the way at 1/2 or 1, I´ve tried to play the notes octave up, down, but it seems I’m missing something. If I import the sample simultaneously into the sampler, the duration of both is not even the same.

Any light shed appreciated
