Patch cables are used to connect the input and output jacks of various modules, creating a signal path and allowing the flow of audio and control voltage (CV) signals between them. Patch cables come in different lengths, colors, and connector types to accommodate different synthesizer formats and user preferences.
The most common connector types for modular synthesizers include:
- 3.5mm (1/8 inch) mono connectors: Typically used in Eurorack and other smaller-format modular synthesizer systems.
- 1/4 inch (6.35mm) mono connectors: Commonly used in larger-format modular synthesizers, such as 5U (Moog Unit) systems.
- Banana connectors: Used in some modular synthesizer systems, like Buchla and Serge, known for their stackable design, which allows multiple connections to a single jack.
