Spectral multimode filter and wavetable VCO

FFT spectral processor mimicking resonant multi-mode filter (low-, band- and highpass) behaviour

Novel firmware for the Electrosmith patch.Init() module. (https://modulargrid.net/e/electrosmith-patch-init)

• 1024 bin, 2-hop FFT processor
• passband base frequency and width under separate knob and assignable CV control for continuous filter shaping
• resonance under knob control; assignable to passband base or upper bound
• crossover junction attenuates sub-350 Hz material entering spectral processing; passthrough to mono-summed, non-resonant 3-pole LPF
• 1024-sample arbitrary wavetable captured via gate; switchable with live input and voltage controllable over 5 octaves
• spectral bitcrush under knob and CV control
• vocoder-esque unvoiced output HF tracking; CV-controlled white noise summed with main output
• amplitude- and brightness-reactive, vactrol-inspired envelope generator at CV output
• true stereo chain with shared parameters

• ? mA +12V
• ? mA -12V
• ? mA 5V
• 31 mm Depth

Module is available as a DIY project only.
