A-110-6 Trapezoid Thru Zero Quadrature VCO

Doepfer's thru-zero quadrature VCO with trapezoid shaping: ten waveforms at once, each in a sine and a cosine phase, and a VCO / LFO switch.

Key features

• Ten outputs: triangle, sine, rectangle and sawtooth, each as a sine and a cosine phase, plus TRASIN and TRACOS
• Exponential section: XTune, 1V/Oct input and XFM input with its attenuator
• Linear section: LFrq and LFM input with its attenuator, for thru-zero linear FM
• VCO / LFO switch: in LFO mode the frequencies are a hundred times lower
• Two bicolour lamps: the polarity of the linear control (TZ) and the TRASIN signal
