I had no idea what you guys were talking about, but I tried it and it sounds wicked. Where did you pick up this idea?

It's simpler than you might think... Take the number that is providing the frequency for the first triangle oscillator and add (or subtract) 175 and 224 to (from) it and use this number to set the frequency of the other two. I'm not sure which direction the frequency shifter is supposed to go in this diagram, so try either adding or subtracting. Also what is not clear is if the original triangle wave is heard in your diagram, or only the two pitch shifted ones, so either you will only hear the frequency-shifted pair or you will hear all three mixed with your two sinus waves. [number box\ <---set master frequency | | | | [+ 175] [+ 224] <---set shifted frequencies | | | | | [triangle~] | [triangle~] [triangle~] Where [triangle~] is an abstraction you have made which produces a nice, bandwidth-limited triangle wave ;-) If my cheap ASCII art doesn't come through, let me know and I'll be less lazy and patch it...
