Thanks @kingcons and @saintcloud. The patch is simply maths in quadrature with the two unity outs into the formants of both mangroves in constant wave mode. Barrel CCW and formant at nine/nine something to trigger pitch divisions. All outputs from the mangroves go to the sputnik mixer while the square of the left one is multed to sync of the right one. The harmonics are generated from an unsynced triangle LFO that comes from an o_C (one channel of quadraturia) and goes into the pitch input of the right mangrove. I think I have said everything. Love this module, but now I want the others. Too bad that in Europe they cost so much!
