Fixed resonant band-pass filter bank (10HP)
Fixed Filter Bank by Yves Usson.
My take on the 914 Fixed Filter Bank. Admittedly, my panel was at least in part inspired by Antumbra's entry, but I decided to build a little wider (there's something to be said for ergonomics as well).
My initial implementation of the input level control leaves room for improvement. All other pots can be linear taper & converted to log-like using the appropriate resistor placeholders on the PCB.
