actually, no :)

I spent quite a while talking to several people a couple of years ago
(including Julius Smith) about the best way to model a pan drum. To do it
correctly is quite challenging. The Pianoteq guys gave me a few hints on
what they had done. I was trying to create an instrument that I planned to
called a "dang drum" (for "digital hang"), but to model the way the modes
of these things interact is quite tricky, and the usual "mode" operators in
Pd, CSound, SC etc, don't really capture the subtleties required.

I was very, very disappointed to find that I had lost the CSound code I had
worked on. The only thing I have left from efforts is a single wav file.
Take a listen if you want. My memory was this involved at least 15
different mode operators in conjunction with some kind of reverb. It sounds
fairly cool, but is really nothing remotely like the real sound of a hang
(or even a regular steel drum).

If anyone is interested, I have a stack of papers on the physics of the
hang drum, including several with clever visual analysis of the instrument
to show the vibration modes, discussions of the characteristics of the
metal used, and so on.
