XO Gold — Mechanical Resonator

XO Gold is a compact experimental percussion instrument built around a mechanical spring resonator with a built-in pickup and digital effects processor. The spring acts as the sound source, which you can play by hand or trigger electronically.

It can function as a percussion instrument, a resonant sound generator, or an unusual effects processor.

Key Features

• Mechanical spring resonator with built-in pickup

• Playable by hand or with trigger / gate signals

• Works as percussion, resonator, or effects processor

• Compact experimental sound device

Sound Capabilities

• Bass drum–like hits

• Plucked and metallic sounds

• Karplus–Strong–style resonances

• Bit-crushed and distorted textures

• Resonant basslines with sequencing

Effects

• Resonant delay / feedback

• Bit-crushing

• Ring modulation

• Pitch shifting

Controls

Three parameter modes (LED indicated):

• 1 blink — Feedback

• 2 blinks — Size / resonance length

• 3 blinks — Time

Each mode remembers the knob position.

Connectivity

• Trigger / Gate input

• CV input for parameter modulation (vactrol-style response)

XO Gold is designed for hands-on experimentation, helping you discover unique resonant “sweet spots” in the mechanical spring.
