July 1, 2024 · 1 sources

Electronic Audio Experiments released firmware V1.0 for the Prismatic Wall in July 2024, according to the firmware changelog on the pedal's product page¹. The changelog lists V1.0 as the original firmware release, following the hardware's Version 1 release in June 2024¹. The page gives no further detail on what V1.0 changed¹.

The Prismatic Wall is a sympathetic resonator that the maker describes as part reverb and part synthesizer, built on a physical string model formed by tuned delay lines, with tuning achieved by varying the sample rate of the system¹. The maker states that the pedal combines 24-bit analog/digital hybrid processing with analog filtering and emphasis, a high headroom analog dry path and mixer, and a 32-bit processor system for digital control of every function¹. Firmware is updated via MIDI Sysex messages¹.

Controls include Tune, which adjusts resonator pitch across a four octave range; Mix for wet/dry blend; Drive, which sets the signal level driving the resonator with overload at higher settings; Damping for high frequency decay; and Decay for overall decay time, which at its upper range adds analog feedback for infinite drones¹. The Mode button selects four string spacing modes: single with harmonic overtones, stacked neutral thirds, stacked fifths, and chromatic¹. The pedal has a multi-mode assignable LFO with periodic and random waveforms, 16 preset slots (3 via the front panel, the rest via MIDI), a CTRL jack for MIDI, expression and CV input, and electronic bypass with buffered or Trails modes¹.

The maker recommends a regulated, isolated power supply rated for 200mA minimum to accommodate startup surges, and states that the pedals do not accept batteries¹. The page lists the Prismatic Wall at $399.00 and marked it temporarily unavailable at the time¹.
