Ripples inverting phase?

hi there !
i was looking at the Ripples schematic and for my understanding, phase is inverted on all the output except the LP4-Vca out.
I verified my assumption in my rack, patching a nice hpf summing a lp out and the initial signal. Very cool result btw.
is it the reason why ?
cheers

No :slight_smile: I did not bother with getting the right phase and used the least number of op-amps.

Haha ok. Thanks for the reply pichenettes.
