Make Noise 4 Zone CV Bus Case 208HP 7U (2026)

The CV Bus is a more functional approach to the “multiple” utility of the modular synthesizer. The CV Big Bus is an evolution of the original CV Bus design from 2013 for Alessandro Cortini's personal Make Noise system. In an effort to accommodate the increased modulation density of the New Universal Synthesizer System, the CV Big Bus doubles the channel count from 4 to 8. These 8 channels are distributed across the center of the system allowing for quick, clean and intuitive patching. The numerical indicators are illuminated providing visual indication of channel number, level, rate and polarity for up to 8 signals to be shared throughout a patch. This distribution method is unlike the typical multiple since the control signals will appear beneath their potential destinations, resulting in less cable mess. The color coding and visual indication makes navigating complex patches easier and more intuitive. Typically, the CV Bus would be used to share the most important control signals in a patch, such as your clock, modulation, sequence, and audio signals - any type of signal the system creates may be shared!

A high quality Stereo Line Driver converts modular synthesizer signal levels to the commonly used Line Level. There are mini-jack inputs for Left or Mono, and Right for Stereo, a single master volume control, as well as a stereo line output pair. The left output doubles as a TRS ⅛” headphone output. These outputs are capable of driving a long cable out to a PA System or a set of Headphones. They are AC coupled with a built-in limiting circuit (with visual indication) that prevents damage to ears and PA system when the patching gets experimental.
