I'll share this one - it will kill the rockers - but it's what I do. This gave cubase a bit of a heartache. The singer has a nice voice, but she slides up to most notes when they start from silence. She doesn't do it inside the phrases. Cubase does pitch and time alignment really nicely I think - but I had to manually sort this one. Cubase shows on the graphical screen each notes as a separate pitch in a colour band, and can break each note into sections, normally syllables, or pitch changes on a single word. With this one I had to deliberately start some notes a semitone flat, so it sounded right - I'd end up having the second 70% of the word dead in tune, but allowing a bit of slide up at the start. There are also huge amounts of BVs - I think maybe 20 or 30 in places - often five different notes in a chord, and these split between two voices, the main singer's and mine - and sometimes to stop them being 'individual' but a wash of sound - each one recorded three times and panned mid left, mid right and centre. One of each part selected as master and all of that line time aligned to match the master. The ends of each phrase left a little different in some places, but in others, tidied up and then faded out at the same time. I think if you know what to listen for, you can probably pick these little things out - you can hear where an odd notes has been recreated with stretching and tuning. I think Cubase did pretty well at this though. No doubt with more time it would have been better, but this she is happy with, and I am too - when it's actually built from one guide vocal and all the good and bad backing vocal takes. It took hours and hours. I've got another, but the guide vocal is just not good enough to repair.
The failed one is Goodbye to love, I'll stick it up if you want to hear how the mistakes are quite exposed, so it must be re-recorded, and of course it has that guitar solo that kind of reveals how I suck at guitar playing - which is why I play bass.
