I was thinking of getting a clone of a 303 for live gigs but I would rather have it inside of Live, don't need more cables for my live sets

Basically what I'm after is a VST that has accents on a midi note so I can make a midi sequence on push and then tell the vsts when the accents are without hopping off the push. Ideally so I can make patterns on it live without any fussing around.
Any suggestions would be great, as I haven't messed with live acid patterns before and the old school banks of preset patterns doesn't really interest me.
Cheers, Sam.
