It would process a keyboard's or sound module's output and alter its sound. Filter sweeps could then be applied to drum loops or harsh sounding digital synths. The unit is made to be fully integrated, all it needs is a sound source. Commercial devices are available, the Mutronics Mutator and the Sherman Filter Bank are examples, but these are very costly. text/html 2024-07-28T22:32:57+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.emusic-diy.org/schematics:oakley:superladderfilter?rev=1722205977&do=diff E-Music DIY Schematics Archive Oakley Sound Systems Super Ladder Filter ---------- The SuperLadder is a voltage controlled filter module designed with modular synthesisers in mind. Cut-off frequency, resonance and envelope sweep depth are all voltage controlled. There are no pots acting as variable resistors in this design. Thus the unit could form the basis of an output card in a polyphonic synthesiser. The basic topology is the old classic, the ladder filter. However, there are some interes… text/html 2024-07-28T22:37:09+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.emusic-diy.org/schematics:oakley:thirtythirty?rev=1722206229&do=diff E-Music DIY Schematics Archive Oakley Sound Systems TB3030 ---------- This a reworked version of the infamous TB-303 bassline. In essence it is just another clone of the analogue circuit of the bassline. However, I have added a few things to make it rather more interesting. I have listened to many peoples ideas on what a TB clone should or should not do, it is clear that some people feel very strongly about this machine. This in the end is therefore a mixture of many peoples ideas, but as the…
