ADDAC129 Resonator — Physical Audio Resonator for the ADDAC120 Four Strings Series
The ADDAC129 Resonator turns ADDAC's Four Strings System into a physical audio processor, using the actual strings to resonate with external sounds. A vibration transducer, powered by a small mono amplifier, transfers incoming audio to the strings, which respond according to their tuning. Their vibrations can then be captured by an ADDAC121 or ADDAC122 pickup. Think of something resembling a spring reverb, but with the character and natural decay determined by four tunable strings.
Feed it synthesizers, percussion or drones, or even route the pickup's own output back into the Resonator to create an acoustic feedback loop. Tuning and damping individual strings changes how the incoming audio resonates. The amplifier has a dedicated input level control, and the assembly can be attached or removed without taking up additional rack space.

About the ADDAC 120-Series
The 120-Series brings real vibrating strings into Eurorack, crossing the worlds of modular synthesis and electro-acoustic instruments. Its four strings form a customizable instrument somewhere between a lap steel guitar, a zither and an automated string machine. The headstock and bridge form the foundation, while additional modules capture the sound, mechanically pluck or mute the strings, excite them magnetically, add frets or even turn the strings into a physical audio resonator. Combined with Eurorack sequencing, CV and effects, you can build anything from a manually played instrument to a fully automated string setup.
