I can’t remember if I posted it here or not, but a few weeks back I computed the summed output of the Buchla 295 10-band comb filter. I realized I had an error in that code in terms of how the highest and lowest bands were treated. Fixing it reveals this graph.

<div class="">The blue line is what you get if you just sum the outputs of the filters. The red line is what you get if you flip every-other bandpass filter and the highpass filter. As Don Tillman predicted, this actually gives you a *flatter* response since
it partially compensates for weirdness in how the *phases* of the different filters interact. <br class="">
