Wow, huge collection of DIY synth circuit diagrams from René Schmitz! Pictured here… Triangle thru zero VCO – “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. I’ve put up several samples here, to give you an impression of the sounds I obtained…” [via] – Link.
