I don't know what is vital, but if You use the chiptone wavs i think theres no problem :)
Viewing post in really specific sample manipulation question
It's a wavetable synthesiser but having played around a bit I've worked out how I think best to use the chiptone samples with it- just as samples lol, using them as wavetables effectively creates a whole new sound, whereas as a sample the chiptone sound is recognisable but you get the other benefits of running it through vital (glide, legato, effects etc)
