Dirty Vegas Track 7 "All or Nothing"

Does anyone know the synth bass used on this track ? It's a synth bass that's been used by many producers on all kinds of tracks for the last 10 years or so. I've been trying to identify it.. Any info is appreciated. You can really hear it near the end of the track. Thanks again.

It sounds like a Roland TB303 baseline played in a low octave to me. You won't get a 100% perfect reproduction of it with any software synth or even any hardware synth I've tried but if you download the demo of Rebirth from propellerhead at least it comes close even if the definition at high or low octaves is totally ropey (to me at least) and for what it is, it's too expensive these days too.

Anyone know of a sample CD containing TB-303 bassline samples ? Thanks

It also reminds me of a Korg Ms20 Bass line heard on "Last Night a DJ Killed My Dog."
