I'm currently trying to model an African thumb piano and so far have managed to model the tone of the instrument using modal synthesis, however I'm having trouble with modelling the rattle or buzz sound some thumb pianos make when plucked. Here's a link to the sound I'm referring to.

Would anyone know of a good technique to model that sort of behaviour? I've had a look at the gen shaker example and it feels like that would be a place to start.

interesting project... looking forward to hearing the results.

I think that gen~ PhiSEM? example is indeed a good start. Did you not get any good results with that?

i've had good results simulating buzzing effects in my tambura model using the filters described in 

. But i think that something like the PhiSEM stuff might be more appropriate in this case since the bottle caps etc that cause the buzzing on the kalimba are separate from the tone generating part

for rattle I'd start by having a look at ppiano~, which I believe is well documented.

I don't seem to have a gen~ PhiSEM example on my computer, is there anywhere I might be able to get access to it?

The ppiano~ rattle is exactly what I'm after, I've found some useful articles by Stefan Bilbao which will probably give me my answer.

i think the gen shaker example is basically PhiSEM
