Semi-modular synthesizers combine the flexibility of modular systems with the ease of pre-patched connections. These instruments allow users to customise signal routing while retaining built-in signal paths, making them ideal for sound designers and performers seeking creativity without needing a fully modular setup. Popular models include the Moog Grandmother and the Arturia MiniBrute 2. With patch points for additional control, semi-modular synths offer a balance between experimentation and convenience, catering to those looking to explore modular synthesis without starting from scratch.
