    Experimental Television Center's Analog Synthesizer is a modular system producing control voltages and synthesized audio; outputs conform to a -5V to +5V standard (10V peak-to-peak) and the unit is compatible with commercial audio synthesis equipment. The studio manual documents two boxes of modules and their controls and jacks — negative and positive ramps, triangle, waveshape shaper, inverter, random, one-shot and pulse, comparators, mixers, dual VCAs, VCFs and a VCO — with operating ranges, VC/gain/bias/Q functions and typical patching techniques. The text includes signal classifications (bias, function, waveshape) and suggested patches for oscillation, gating, sampling, panning and filtering.
