3320 Multi mode filter :

I've got the chance to get some CEM 3320 to repair my SYNTHEX, and I have decided to use at least on of those to realize a filter. I decided to go for the principle of 4 Low pass filter mode where with the right ratio and sign you can get any filter type.

Read the technical article from Olivier GILLET from MUTABLE on his filter: (SSM2164 4-pole with pole-mixing). This principle was also used on the Matrix 12 from OBERHEIM. There is also some infos on ELECTRONOTES.
