DoepferA-110-6 Trapezoid Thru-Zero Quadrature VCO

Doepfer A-110-6

The A-110-6 from Doepfer is an all-analog oscillator with five pairs of quadrature waveform outputs and thru-zero linear FM capabilities. It features a unique trapezoidal waveform in addition to traditional sine, saw, square, and triangle waves, along with a Linear Frequency knob which controls the polarity of the trapezoid waveform. Along with the Linear FM input, this can be very useful for "biasing" the module's thru-zero element in order to unleash FM pandemonium. In its audio range, the oscillator tracks 1V/octave well, while its LFO range switch makes the A-110-6 an extremely powerful modulation LFO as well.
