How it is made
Original sOURnd design: per spring, a delay loop through forty first-order all-pass sections with a shared negative coefficient (frequency-dependent group delay, so dispersion grows with every round trip), one-pole damping and low cut inside the loop, RT60-derived loop gain, band-limited mono input, an onset detector that injects extra high-passed energy and kicks a decaying sinusoidal wobble of the loop delay, and fixed stereo placement per spring.
