Harmonic Touch Terminal

The Mechanics:

The Harmonic Touch Terminal is a standalone desktop performance controller and signal processor housed in a powder-coated anodized aluminum chassis, bridging the tactile tradition of West Coast touch-plates with modern digital bus routing. The interface features a two-row array of twenty-four gold-plated, capacitance-sensitive brass touch pads that map pressure, surface area contact, and lateral positional drift directly to multi-channel analog control voltages via high-precision discrete JFET input stages. Beneath the tactile surface, an internal STM32H7 microcontroller samples analog touch data at one megahertz, translating micro-gestures into both standard +/-5V analog control signals and low-latency USB-C MIDI Polyphonic Aftertouch. This hybrid architecture eliminates conventional mechanical keybounce and spring fatigue, offering instant, zero-latency physical feedback that drives internal analog slew generators and complex timbre circuits.

Power and signal distribution are handled through an internal bus board compatible with standard Eurorack power rails while operating autonomously via an integrated, rechargeable lithium-iron-phosphate battery pack rated for eight hours of continuous live performance. The rear panel provides twelve banana jack CV outputs—standardizing the Buchla interconnect philosophy—alongside four 3.5mm mini-jack adapters to interface seamlessly with modern modular systems. The internal analog core features a dual-oscillator discrete transistor sine wave generator derived from the Harmonic Generator topology, allowing the touch plates to instantly modulate harmonic spectrums, fold depth, and transient decay envelopes purely through finger capacitance without requiring patch cables for baseline operation.

Utilitarian Value:

This architecture unlocks a high-margin revenue stream by packaging the esoteric appeal of West Coast tactile synthesis into a self-contained, highly portable instrument that lowers the barrier to entry for non-eurorack electronic musicians. By utilizing existing discrete transistor designs and pairing them with high-density surface-mount digital control layers, Verbos Electronics achieves a substantial reduction in per-unit manufacturing complexity compared to fully modular systems while commanding a premium retail price point. The inclusion of dual-standard connectivity (banana and 3.5mm) captures both purist modular traditionalists and modern hybrid DAW performers, driving high-velocity inventory turnover and expanding gross margins through proprietary hardware accessories.

Target Ecosystem:

Boutique electronic music hardware market, aimed at live techno performers and avant-garde sound designers operating within Berlin-style modular and DAW-less performance setups.
