A-143-4 Quad VCLFO/VCO

Doepfer A-143-4

The Doepfer A-143 offers four voltage-controlled oscillators with individual reset/sync, voltage control, and range switches per channel, as well as common CV inputs, manual frequency control, and summed outputs. Though it's primarily intended for use as a quad VCO, the A-143's ability to switch each channel into the audio range makes it a capable source of thick detuned oscillator sounds as well.
