- Add delay and reverb Dry/Wet parameters and knobs, wired into presets - Add Accent/Slide/Fine/Rate toggles to the Randomize panel with new per-aspect pattern randomizers - Soften accent: modest volume lift plus small cutoff and filter-attack modulation instead of the heavy 5x gain boost - Halve reverb comb/allpass delays so the wet speaks sooner - Regenerate a fresh build stamp on every build
