Visualizing Music and sound on Grasshopper, Need advice and assistance

Hello all those in the grasshopper community, I'm an experimental music composer who has written some pieces involving long duration (4 minutes) sine waves sliding between pitches. I have 8 sine waves going at the same time. I am trying to build an engine in Grasshopper that will do the following things:

1) Display a surface that will flex and bend in relationship to the frequencies of the 8 sine waves.

2) Allow me to take a snapshot of the topology of the the plane of each moment of the piece of music.

3) Possibly allow me to create a 3D form of that specific moment in time, thereby allowing me to create a 3d print or fashion a sculptural form from the waveforms.

I am a relative newbie on Rhino and Grasshopper, so any help would be most appreciated.
