Triangle thru zero VCO by René Schmitz ,visit his page for more details on this VCO , demo sounds , other synthesizer modules designs as well as OTA Tutorial and in depth guide on exponential convertors and temperature compensation http://www.uni-bonn.de/~uzs159/index.html the short description on this Oscillator by René Schmitz :

A thru zero oscillator is one that can go forward and backward. This allows for deeper frequency modulation. Sonically there are interesting a little yamaha-ish sounds possible. This oscillator sounds somewhat dirty when the modulation index is time variable. But clean non-time-variant timbres are possible.
