I use Cubase and have done since 1995.
i also use presonus studio one, because of ARA integration with melodyne. this is the biggest feature i'd like to see in cubase. I've asked for it for a couple of years, but no sign of it. now sonar is getting it. for those who haven't tried it, it makes melodyne the slickest,fastest and BESTEST! way to repitch audio. here's the sonar announcement. p.s. this post is not for those who say we don't "need" pitch correction. I don't "need" charlize theron, but could certainly find uses... http://www.celemony.com/cms/index.php?id=ara_sonar
