Audio Pitch Question

[Wavelabs]

I am trying to change the pitch of an audio vocal
without changing the speed of that vocal.

I am only going 4 semitones down.

the original key of the song is in B-min.
but when playing keyboards to this vocal, it sounds like total crap.
I did not like how it sounded on that key, so I decided to change the key and I said to myself,
I can do better 4 semitones down.

so what I did was created a great bassline and keyboards 4 semitones down
from B-min and the track itself sounds much better.
but now I just need to bring the vocal down.

NOTE:
AGAIN --> there is no [right click] menu to choose change pitch or at least
a right click menu to change by semi-tones.

other than my major complaint about this.

I would like someone to please inform me as to how to change the pitch
to a vocal audio without having to change the time of that vocal.
I tried [AudioSuite] pitch shift and only change the pitch 4 semitones down.
and the vocals sounds horrifying and sounds like the devil came from hell
bass toned vocal.

I am very shocked because I am only going 4-semitones down
and NOT an octave or two.

its strange how this is behaving.


im using a second friends system
