Stereo 8-band filterbank with vactrol-style ping excitation and acidwarp video viz. Eight RBJ bandpass filters at octave-spaced centers (80, 160, 320, 640, 1280, 2560, 5120, 10240 Hz, Q=6). Each band carries its own ping gate input — rising edges distribute excitation across n±2 neighbors via a 1.0 / 0.35 / 0.12 bleed matrix into a vactrol envelope (soft-attack 10-30 ms with ±10% jitter, exponential decay 100-800 ms with ±10% jitter, tanh-saturated). The envelope simultaneously injects a fast broadband click into the bandpass (filter rings at fc) and pumps the band gain. viz_out is a mono-video cross-domain bridge: the on-card EQ-curve + audio-waveform overlay + cycling acidwarp hue palette + per-band ping flashes are also published as a video texture for downstream video modules.

A stereo 8-band resonator bank you play by striking it — like a tuned set of 8 ringing filters. Audio into the stereo inputs runs through 8 bandpass resonators, tuned either as octave-spaced log bands (a spectral EQ, ~80 Hz–10 kHz) or as harmonic partials of a ROOT note (harmonic mode). Each band has its own PING trigger: a rising edge fires a vactrol-style excitation envelope (soft attack, exponential decay, slightly jittered) that both pings the bandpass into ringing at its centre frequency and pumps its gain — and the energy BLEEDs into the neighbouring bands (n±2) for a more natural, coupled response. GLOBAL PING strikes all 8 at once. Per-band sends/returns (band{N}_out / band{N}_in) let you route each partial through external effects; per-band LEVEL, plus Q (resonance), SPREAD (stereo pan width), and DECAY (ring length) shape the whole bank. A built-in acidwarp video visualizer draws the live spectral curve.
