Hi,
I want to create a Modular patch that models the sound of a large single-headed drum with a long decay.
I have in mind, particularly, the sound of a timpani or even the kind of hand-drum that is basically just a tuned head (about 18" wide) with a very shallow shell. This kind of drum (sorry I dont know the name) you typically play by tapping the edge of the head with your fingers. You could also imagine the kind of flanged "bahwongwaaahhh" sound you get when you strike a well-tuned, unmuffled tom-tom near the rim.
It's difficult for me to comprehend all of the physics involed in an oscillating drum head. I can imagine there is a basic tone that is described by the resonant frequency or tension at the center of the drum head. But beyond that, it gets very murky for me.
Does anyone have any suggestions for an approach to creating a Modular patch for such a model? FM synthesis seems like a logical choice to me. I assume that as the center of the drums head oscillates, it changes the tension of the head in other places, affecting the resonant frequency there, which in turn affects the tension in other places, etc. etc. But I can't seem translate this theory into an FM algorithm directly. Frankly, I don't even know where to start.
Any suggestions or other ideas?
Cheers,
Bill D

The FM part I knew, but they add some other techniques as well!
