Hi all. Sorry if this seems like a stupid question, but I'm an art student who is taking a course in interactive electronic art, and I need to write a patch that can illustrate the vibration of something based on the pitch of sound coming through. The pitch is being controled from another patch. I've been told that my patch (the vibration patch) is supposed to be utilizing a GEM window for the visuals of vibration...I haven't a clue where to start, and the pressure is on to get this done. So far I've only figured out vague use of GEM window, and I don't know how vibration can be similated. Please help give some pointers. MANY THANKS

thanks for the pointers. I have another question about representing the tabwrite (waveform) graph in the GEM window is that possible? How might I go about that?
