Hi, 
it deepends what you need _
if you want a real time pitch correction (Audiodeluxe is still accepting 
Waves voucher ) you can get Waves pitch correction aso for cheap.
 
Or a small version of melodyne which is also Splat included.
Don´t know if the price difference from Melodyne to a Splat uodate is 
relevant for you.

SPlat= SONAR Platinum.

will waves Tune work in any DAW?

aww man  I chatted with them and they said MC 7 doesn't support V9 plugins. :(  with the discount I would have only paid $39 
 

I used Melodyne in Music Creator without any issues. 
 
However,  you need to check the compatibility of the MC version you have to the version of Melodyne essentials you would be buying.

Essentials is just as solid as the top of the line Editor version. It just has less bells and whistles and only does certain functions. As long as you can correct pitch and move timing of notes, you should be good because that's all I really do with ME anyway.  I never use the auto-correct or group correct function. It's all a note by note process for me.

Sorry to read that , but as far as I can find out 
MC 7 can read VST 3 Plugins:

Introducing Music Creator 7

Version 7 of this best-selling software makes it even easier to produce exceptional tracks thanks to the integrated MixStrip, one-knob “Style Dial FX” for shaping your sound, touch screen compatibility, and VST3 plug-in standard support—so you can use cutting-edge instruments and effects from Cakewalk and dozens of other manufacturers. Then when you’re ready to share your music with the world post your music on Facebook and Twitter with SoundCloud.
 
So can some of the more experienced MC
user clearify if MC 7 can read Waves Tune  (means Waves V9-VST 3) pluggis ?
 
Do you need a real time pitch correction?

Is waves tune a vst 3
 

Yes ,you choose during the instalation  if you need :
vst ,2or 3 and/or  32 / 64  bit.
Sonar is not official supported by Waves,
but you can find many Sonar users running Waves Pluggies.
 
A  pitch-correction like Waves Tune you will like for live situations
and slight correction in realtime.
A tool like melodyne works not in realtime and with bigger buffersizes
like 1024 samples .It´s not possible to use it in real time, but you can 
manipulate the voice much more and precise in intonation and timing.
Melodyne is used in studios for vocal editing.
 
If V9 is not supported byMC 7, V8 should  work.

Sonar is not official supported by Waves,

Yes it is for VST3 format http://www.waves.com/support/tech-specs/supported-hosts
and since MC7 is based on X3, it should have no issues. That said, I have no first-hand experience with Waves plug-ins.
