Prismatic Wall is a sympathetic resonator designed to transmute incoming sounds into the vibrations of an illusory bank of tuned strings. Part reverb and part synthesizer, its metallic yet warm timbres span from the subtle harmonic aura of a third bridge to the rich chromatic suspensions of a grand piano. The simulated vibrations form a sustaining spectral extension of your instrument that retains a tangible physicality despite its surrealist underpinnings. The resonances are reactive in nature: playing in tune excites specific pitches, while percussive attacks excite all the strings in tandem.

Prismatic Wall utilizes a physical string model formed by tuned delay lines. Tuning is achieved by varying the sample rate of the system, manipulating the physical model in decidedly non-physical ways. The Mode selector determines the interval spacing between strings, with each configuration carefully selected to maintain a sense of harmonic ambiguity. Damping and Decay change the brightness and sustain of the strings, ranging from short plucks to infinite drones.

The hardware combines primitive DSP with analog saturation and filtering for a sonic character untethered from a particular era. A fully digital user interface enables all parameters to be controlled via MIDI, saved as presets, and even modulated by the onboard LFO. In addition, the Morphing function enables controllable transitions between two distinct settings via the Aux footswitch or an expression/CV source.

Prismatic Wall is a distinct instrument in its own right, a device that refracts musical intent into a manifold of harmonic colors. Will you traverse its intricate layers?

Tune: adjusts the pitch of the resonators across a four octave range

Mix: wet/dry blend

Drive: sets the signal level driving the resonator, with overload at higher settings

Damping: high frequency decay of the resonators

Decay: overall decay time of the resonators; at its upper range also adds analog feedback to create infinite drones

LFO Rate: LFO speed; modulates Tune by default

LFO Amount: LFO amplitude

Mode Button: selects between four string spacing modes: single w/ harmonic overtones, stacked neutral thirds, stacked fifths, and chromatic

Wave Button: selects the LFO waveform between periodic and random modes. Long press to access the Mod page.

Engage Footswitch: activates the pedal. Long press to toggle trails/standard bypass modes.

Aux Footswitch: the footswitch behavior depends on the Aux button setting. In Morph mode, Aux will jump between two distinct knob settings with intelligent momentary/latching behavior. In Preset mode, Aux will scroll through the first three presets.

Aux Button: determines the behavior of the Aux footswitch. Long press to access alt functions, and press again to return to the panel.
