Fixing Mis-Aligned Multitracks

I'm not sure if this is a newbie question or not. I'm multitracking audio (vocals, bass, etc.) and my timing is off here and there. I'm attempting to correct things by repairing things manually. I'm aware that Reaper has a feature for automatically detecting and splitting audio tracks into chunks, but that's not helpful in this case because there are no transients that flag split points - I'm essentially picking random places in the performance that need repair. For example, consider a track with the vocal "Maybe I..." that cuts off too soon on the held "e" of "Maybe", I can just split the vocal into three parts, like so: Code:

The easiest other way to do this is getting which lets you treat audio as MIDI. But it's unfortunately quite expensive. I hope someone chimes in w alternative / freeware suggestions.

Thanks! Melodyne is very slick, but out of my price range. Reaper has a Dynamic split items which uses a gate to trigger the split, but that's based on the gate being triggered by volume changes. I guess what I'm really looking for is for a Dynamic split items that could be triggered by pitch changes. ReaTune does a good job detecting pitch changes, so it should be technically possible to do this sort of thing. I'll take my question to another thread, unless someone has another suggestion.
