This week I extended the fft crossover to encompass 5 bands.
I was interested in extracting frequency specific information for use as a controller but don't quite understand what information the fft process actually creates.
I found it interesting that you can create dead spots in the crossover by setting them in the middle of the same bin, so I have done a fix on this - although it does require the DSP to be switched on as it uses the FFT fundamental frequency.
