What DAW, if any, are you using? Many DAWs can do this, it just takes a little work.

As JosieC indicates Melodyne can do it. It you have Sonar it can do it as Sonar includes a version of Melodyne. I'm sure other pitch correction software, DAW or wave editors can do it.

I would, in Sonar, convert the lead vocal to MIDI then merge all of the different MIDI notes to one. This would give you one MIDI track with the exact timing as the vocal. Just choose your MIDI sound and you are all set. If you wish I could do this for you.

Ps- Probably that is what JosieC would do for you also.

My goal this weekend is to move just enough each day so that no one pokes me to see if I'm dead or not.

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
