Best way to warp long vocal sample in Renoise?

The original vocals that I used in my D&B track which I posted a few weeks ago (https://forum.renoise.com/t/lost-and-delirious-liquid-atmospheric-dnb/45814) are not in sync with the BPM I was working with (168 bpm).

In order to use the vocal in my track I had to find a method of syncing it up. Timestretching was a no-go because it results in ugly artifacts and pitch shifting the vocal would make it out of tune. So I went on applying a combination of 0Sxx and 0Bxx commands. I would trigger my desired vocal cue (the “hah-ah-ah-ah-yeah”) with 0Sxx and prolong it by looping the individual trails with 0Bxx. Each cue and looping had to be fine tuned with the delay column settings to get the timing right and to avoid pops. You know what they say about trackers: The limitation of the software is where the real fun starts. You can get very creative when you have minimal tools to work with. That’s what I love so much about Renoise.

Here’s the original vocal for reference: http://www99.zippyshare.com/v/oBnXqc9g/file.html
