Problems with building granular synth interacting with Absynth 5

I am trying to make a granular synth using live input from max and was told that a good route might be using Absynth 5 as a vst in Max and having Absynth deal with the sound. I am not sure how I can get the sound into absynth as a vst. An idea I had was to take the input, periodically put a grain of it into a buffer, and then send it to Absynth for synthesis. Does anyone know a way that I could get my buffer into the vst? I could possibly loop the buffer and send it through the vst, but that is more having Max do the granular synthesis... Any tips or resources on the topic would be appreciated.
