Nibbler - Four-Bit Accumulator Alternate Faceplate The VCOb is an voltage-controlled

The VCOb is an voltage-controlled analog oscillator based around a classic triangle core VCO

length and playback mode can be adjusted

The SUB output can generate a square wave at the oscillator’s fundamental frequency

According to Serge

Nibbler - Four-Bit Accumulator Alternate Faceplate The VCOb is an voltage-controlledThe 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).
