VST sampler

Hello.
I just bought a really cool instrument. I want to record it, put it in a sampler, then use it as a vst synth. So it need to pitch the original recorded note, and i want to chose the length, program it in the piano roll. Is it a free VST that can do that for me? NB: i use a mac.

you could give Groove Agent SE a go (in case you own a legit Cubase copy)
