The Prismatic Wall is a sympathetic resonator pedal that uses physical modeling synthesis to simulate the sound of an imaginary ensemble of vibrating strings. It creates an immersive and harmonic texture that blends elements of reverb, chorus, and synthesis. Designed for experimental soundscapes and unique tonal layering, it uses a hybrid analog/digital architecture to provide expressive, high-fidelity resonance with dynamic modulation options.
Key Features:
Physical Modeling Resonators: Based on the Karplus-Strong algorithm, the pedal models up to four independently tunable virtual resonators.
Four Harmonic Modes: Choose from Unison/Overtone, Stacked Neutral Thirds, Stacked Fifths, and Chromatic intervals for various harmonic textures.
Morph Functionality: Seamlessly fade between two different parameter settings using the footswitch, an expression pedal, or control voltage.
Multi-Waveform LFO: Assignable modulation with both periodic and random waveforms for evolving sound movement.
Full MIDI Support: Control all parameters via MIDI CC, including preset changes and real-time automation.
Analog Drive and Filtering: Pre-resonator drive section adds harmonic coloration; post-resonator low-pass filter shapes the output tone.
Bypass Options: Buffered bypass with optional trails mode for natural decay when disengaging the pedal.
Controls:
Tune: Adjusts base pitch across four octaves.
Drive: Sets the input gain into the resonators.
Decay: Controls how long the resonators sustain.
Damping: Affects the brightness of the decay.
Mix: Blends dry and wet signal.
Wave and Speed: Controls for LFO shape and rate.
Aux Switch: Assignable for morphing, tap tempo, or preset switching.
