in trying to learn more about the nuts & bolts of modular synthesis, i've seen triangle core VCOs being a hot topic keyword and haven't been able to keyword search anything that explains WHY. i've checked youtube demos for intellijel's super popular dixie II+ out and didn't hear anything different than a standard VCO, or even digital ones doing standard sawtooth, sine or square waves so there must be something i'm missing as it seems more like marketing hype than some revolutionary way to get new & exciting tones like you can with a wavetable VCO.
what's the big deal about triangle core VCOs? i can hear a lot more variation between VCFs
