The Nandamonium by Synthrotek combines two of the "Chaos Nand Synth" and adds two ribbon controllers and an echo effect. Each of the two sides consists of three rectangular oscillators, which influence each other (3>2>1) and create a colorful palette of pulsating drone sounds, sci-fi noises, wild pitches and rtling sound clusters. Fortunately, the Nandamonium contains two of them, which are brought together in an echo effect! Four of the total of six rectangular VCOs are integrated into the sound generation with a toggle switch; the other two have a volume control.
