[sdiy] help finding roland filter schematics?

Wed Apr 29 19:37:42 CEST 2009

by the way...would anyone be interested in knowing the results of these experiments with the roland FILTER CHIP schematics? or has it already been done a million times?

in other words, i am going to try and figure out if i can make a jupiter filter,etc with a standard 13700.

thanks

> The SH-1000, SH-2000, SH-3 (not SH-3a), SH-5, System 100 (not 100M) and TB-303 all used diode or transistor ladder filters. All others, as far as I know, used OTA designs, though there were plenty of variations (using 3080, BA662, custom chips that included buffers and a resonance OTA, in both 4 pole and state variable topologies).

>> btw...are there any other missing roland series that use OTA filters? i know the DELTA does...any others?
