Sequencing Guitar Tremolo's?

[kizoxef]

I was wondering if any of you knew how to sequence guitar tremolo's somewhat realistically? Yeah I'm really not sure how

Heres an example of the type of sound I kind of want in the tremolo.

Your only option for *convincing* tremolo picking is to find a sample set that has pre-recorded tremolo picking.

Or there's the obligatory "learn to play guitar yourself"-suggestion, because guitar is one of the hardest instruments to realistically sequence with samples, but one of the simplest instruments to learn.
