I had a mess about with modelling drums using delay based laminas with feedback and fm to make non linarity. I was inspired by some Eduardo Miranda and Perry Cook work. It's pretty rough, and basically it doesn't really work so well because I found the scalings hard to set up, getting the parameters is fiddly. All the same I thought it worth posting because someone might want to play with it improve it. Changing to lower blocksizes might give a smoother sound for the snare , the controls could be scaled better and the kickdrum needs a phase reset and envelope zero to stop occasional clicks. And plenty more could be done with note velocity parameters.
Anyway there's a snare drum that has a separate snare and skin and two exitor sources, a displacement impulse and a rattle from the snare coil. Theres a kick drum that has a beater and skin. For both you can set the pitch (tightness), and diameter, but I left all 3 delay parameters accessible to mess with. Snare skin model has self-feedback. The kick drum there is FM with self feebcak which gives the effect of a loose skin which tightens with the displacement impulse if you get the settings just right. Finally there is an FM hi-hat, which is a bit shit but I am still scratching my head over how to build a model of two cymbals that can rattle against one another, some way to express a symmetrical coupling. Attached is the kit to listen to. And there's a few new sound effects generators here too http://www.obiwannabe.co.uk/html/news/news.html The machine-o-matic (with deluxe quadruple action) is a good laugh if you like making weird machine sounds.
best,
