[sdiy] 36dB VCF output drop while increasing emphases

[Quincas]

Maybe you can use another 13700, make a vca and a voltage follower as an output compressor? 36db seems already very steep, I'm a 2 pole man myself :) don't know how much difference you'll get with 48, but I think you should try it and hear for yourself, maybe the sonic character becomes something quite unique...

This can be compensated with increasing the output gain while increasing Q. But then the peak level of the output will be way higher as the normal output. Which might cause distortion in the next stage. Is there a compromise to avoid this or do i need to select: Lower output or increased distortion?
