Karaoke Forums

So I'm new here, being "musician" I used to have "negative" feelings about karaoke stuffs and I discovered this very interesting hobby by chance (to train my voice is more motivating than doing that only with my songs...)
I discovered this hobby from an internet site and ordered a RSQ e500 (I 'm waiting to get it):..

I have already one question : on the rsq e500 I read it's possible to change the key, is it by semi-tone (the easiest way), sorry if this question is not so clever for experts as you are
thanks a lot,

me too.  cool site , huh..
