Nibbler - Four-Bit Accumulator Alternate Faceplate or the characteristic comb filterThe Nibbler is a logic module (a CMOS based four bit digital accumulator) which generates two stepped voltages and four gates in sync with an incoming clock. It explores the idea that counting in binary (and its expression in bits) is inherently musical, and with slow clock speeds we can use it to create both rhythms and modulation voltages (or melodies). At audio rate we can generate subharmonics and modem like sounds (or noise).
