Absolutely love it! I have no voice anymore but I was able to sing a few notes, then in Vielklang bump them up to the correct key, then add perfect sounding harmonies.
I especially like the drift control - you can see all the waviness in the waveform of each note and correct it up to 100% and even after that sounds totally human.
It also works with instruments. Great attentive, personal, fast tech support too.
I can send you a short sample of what I did if you want. Just let me know.
Thanks! Bernie
