Haptic Resonator Interface

# Haptic Resonator Interface **The Mechanics:** The Haptic Resonator Interface is a modular, high-mass tactile surface array designed to integrate directly with the Stereo Field and Noon signal paths. Each unit utilizes a piezoelectric-ceramic transducer bonded to a CNC-machined, brushed-aluminum surface plate suspended by variable-tension silicone gaskets. When the user manipulates the plate, the physical displacement generates high-fidelity control voltage (CV) via an integrated ultra-low-latency analog-to-CV converter, while simultaneously acting as a contact microphone for acoustic resonance. This dual-purpose architecture allows the performer to inject physical micro-vibrations—such as fingernail taps or surface friction—directly into the modulation bus of the Noon drum synth or the audio path of the Stereo Field. The architecture employs an internal passive gain-staging circuit that requires no external power, drawing phantom voltage from the host instrument’s CV inputs. The physical interface is housed in a bespoke, reclaimed-steel chassis that provides a grounded tactile anchor for live performance. Signal throughput is managed via a dedicated 3.5mm TRS breakout port, allowing the plate to function as either an expressive modulation controller or a source-material capture device for tape-based FM manipulation. **Utilitarian Value:** This product effectively bridges the gap between passive acoustic performance and active electronic synthesis, creating a high-margin hardware accessory that forces deeper integration with existing Landscape units. By positioning the interface as an essential sonic "input" rather than a mere controller, the brand increases the lifetime value of the customer’s existing rack and creates an immediate secondary market for tactile-specific sound design expansions. **Target Ecosystem:** Experimental analog modular performers and tactile sound-art practitioners requiring organic, non-quantized control surfaces for live electro-acoustic improvisation.
