Filters Can Be Oscillators

What I love about the Buchla system is that on this machine the normal rules of synthesis are meant to be broken. Here is a patch which uses the 291e triple band pass filter as the only sound source. This module is primarily three individual filters / VCAs but it also has a built in 8 step sequencer and the ability to morph between different filter settings. Also if you feed back the resonant filter output into itself you can create three audio-range VCOs and that is what I am doing here


  1. What's the paper faceplate to the left of the P/R?
