Electronic Audio Experiments releases Prismatic Wall firmware V1.1
August 1, 2024 · 1 sources
Electronic Audio Experiments released firmware V1.1 for the Prismatic Wall on August 1, 2024. The version starts on serial #326, according to the maker's changelog1.
The update fixes a bug that can cause the panel to load improperly on startup, and a bug where unexpected sysex messages (SPP, MTC and similar) can cause the UI to crash. It also improves tuning in Quantize mode, reduces LFO jitter and improves the sound of audio rate modulation, and makes preset loads that do not change the Mode setting load seamlessly. Long pressing Preset now allows program change messages to save to the corresponding slot, which the maker says works the same as its Sending V21.
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. Tuning is achieved by varying the sample rate of the system. The pedal has controls for Tune, Mix, Drive, Damping, Decay, LFO Rate and LFO Amount, a Mode button selecting four string spacing modes, and a Wave button selecting periodic or random LFO waveforms. It offers 16 preset slots, three accessible from the front panel and the rest via MIDI, and firmware is updated via MIDI Sysex messages1.
"Prismatic Wall is a sympathetic resonator designed to transmute incoming sounds into the vibrations of an illusory bank of tuned strings"
