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

Sorry to sound a bit like a teacher here, but ... first you have to know what it is exactly you want to do.

representing the 'vibration' can be done in many ways. And not necessarily with GEM.

Have a look at the help file for [tabwrite~] that is the most basic form of representing the vibration, or the waveform, if you rather.

First get to grips with GEM. Go through the tutorial in PD... Browser > manuals/ > 2.Image/ > +pager.pd

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?

this thread has some graphing of tables in Gem:
