Why on earth would you want to use wavetables???  That would give you a 
finite number of waveforms, whereas using sliders gives you infinitely 
many.  The output sound varies significantly with even a modest movement of 
even one slider.  So you can experiment sliding around until you find a 
sound you like, or you can fine tune to a target sound.  Additionally, 
static waveforms are boring.  You can move sliders in real time for 
interesting timbral variations.  If you want reproducibility, you can take 
photos of the sliders.
