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.
That´s a new info for me, thanks.
So I can recommend Waves pluggies to you, which are running flawless
on my system for years.
It depends on your needs, still no comment of you if you need a realtime pitch correction or not .
