Er... the reason it wasn't sounding right is because the final product has the vocal reversed. You were doing it right to start with:
- Reverse the vocal part,
- Add the 'verb,
- Reverse again - then the vocal is playing the right way, and the reverb 'tail' is now a lead-in.
Whether you want a copy under the original, just the reverb on a seperate track or anything else is up to you, but the principle is the same.
One thing to keep an eye on though - if you split the track so the "I" is on it's own, you have to make sure the reverb actually has a tail (increasing the length of the clip), and doesn't cut off when that section of the track finishes. In the Sonitus reverb there's a button called 'tail' that does exactly that.
