Opti Deko

Opti Deko is an innovative, modular hardware extension designed to instantly elevate the expressive capabilities of standard MIDI keyboards. Placed easily on top of keys, it expands fluidly through a magnetic connection system that snaps units together for quick physical and electrical linking, creating a flexible environment for next-generation music performance.
Equipped with high-precision optical sensors, Opti Deko tracks subtle finger movements on the keys, allowing musicians to intuitively control parameters without lifting their hands. Developed for modern production, it fully supports MPE and MIDI 2.0. From smooth slide modulations to advanced microtonal exploration, this developer-ready prototype empowers performers with unparalleled, real-time sonic flexibility.

Unlike expensive, all-in-one expressive synths, Opti Deko simply sits on top of any keyboard. The magnetic connection snaps units together, handling both physical alignment and data bridging instantly.
Instead of pressure-sensitive pads, high-precision optical sensors track finger movements on the keys. Musicians gain seamless, fluid modulation without lifting their hands.
It features native support for MPE and MIDI 2.0. It delivers per-note polyphonic modulation and high-resolution data integration with modern DAWs, bypassing old MIDI 1.0 bottlenecks.

The most inspiring use of Opti Deko is unlocking seamless multi-dimensional expression directly within the natural flow of keyboard playing.
Opti Deko’s high-precision optical sensors read the subtle, forward-and-backward depth movements of the fingers while pressing the keys. Imagine striking a physical chord and instantly sliding your fingers along the key’s length to morph textures, introduce fluid microtonal pitch bends, or shape organic filter sweeps—all without ever losing physical contact or lifting your hands away.
Opti Deko bridges the gap between traditional keyboard playing and next-generation sound design, allowing players to fluidly command MPE and MIDI 2.0 parameters through intuitive, tactile depth control.
