disable generative evolution globally; tame resonance, cross-mod and reverb drive

Browse source 
Zero EVOLVE/WARP on all 195 presets to remove the wind-howl sweep (filter cutoff, resonance, warp bias, detune sway no longer wander). Gate cross-mod bloom by EVOLVE so it stays static when off. Also settle voice-screen params, oscillator/filter levels and fx saturation.
