Hi

I found a paper published in 2003 entitled "digital implementation of the moog ladder filter" (the one muug~ is based on), and it made me wonder if there are any other papers like this

Does anyone know of any papers or sites that give information on how to design digital copies of old filters?

I'd really like to find the ARP filter, Oberheim filter and the Curtis filter out of the sequential circuits and dave smith synthesizers

Thanks

No, sorry
I meant implementing a filter that models the behavior of old analogue filter chips, the non-linearities and stuff, much like the guys who made the [moog~] and [muug~] filters did
thanks
