The harmonic you mention for the triangle are not exactly right, actually they are the same as for the square, only odd ones, only their amplitude decreases faster, for the square the amplitude for harmonic n is 1/n for a triangle its 1/n*2. The filter should have a slope of 6dB to get that attenuation. On a scope you would not see a perfect triangle however as a filter has a phaseshift. For audiofrequencies thats inaudible, but for an LFO used to modulate something else that would be audible in the modulation sweep. That however might be an interesting feature. . And a patch as an example. . On the VCS3 the sinewave is made by sending a triangle wave through a symmetrical exponential converter (two simple hardware diodes will do that job with the right signallevel within something 5% distortion). On the NM you can use a Shaper module for that purpose. Adding a little positive or negative voltage to the input triangle signal of the converter will make the converter behave nonsymmetrical and so change the waveform to have some more harmonics. A condensator is then used to remove the added voltage. On the NM a 6dB highpass filter set to 12 Hz will work like such a condensator removing DC components from an audiosignal. That was in the earlier patch. . Rob .
