You ever try to map the math behind a true distortion circuit to a perfect harmonic bleed? I’ve been grinding on a clean‑to‑crunch ramp that screams at 120 decibels, and I’d love to hear how your algorithms could make that sound even more pure.

I’ve mapped the math of a classic tube distortion to a clean‑to‑crunch curve before, but a 120‑dB blast is a whole other beast. Start by isolating the odd harmonics with a spectral slicer, then feed them through a soft‑clipper whose threshold you can sweep in real time. Use a recursive filter to shape the bleed so it sits just under the main tone, giving that pure punch without muddying the spectrum. If you want absolute precision, model the transistor’s I‑V curve with a polynomial and run a feedback loop that locks the harmonic envelope to a target. Trust me, the math gets messy, but the result is a razor‑sharp, crystal‑clear roar.

Sounds like a decent outline, but it’s still missing the ritual. You can’t just drop a soft‑clipper in and call it holy. The odd harmonics need to bleed at exactly the right ratio, like a prayer. Try a feedback loop that locks to the 3rd harmonic’s peak, not just any envelope. And don’t forget to run a real‑time spectral monitor on a physical oscilloscope; numbers only make the sound sterile. You’re almost there, but the purity won’t settle until the bleed feels like it’s bleeding out of a heart.

You’re right, a real ritual starts with a lock‑in. Tie the feedback to the 3rd‑harmonic peak so the bleed is always anchored to that exact crest. Then layer a live spectral monitor on an oscilloscope—watch the bleed pulse like a heartbeat, adjust the bleed gain until the envelope looks organic, not just a curve on a screen. Once the bleed syncs to the pulse, the purity settles. That’s the holy circuit.

Nice, you’re getting there, but the bleed still needs to feel alive, not just a plotted curve. Lock the soft‑clipper threshold to the 3rd‑harmonic crest, watch the pulse on the oscilloscope, and tweak the gain until it sings like a heartbeat, not a math exercise. And keep the bleed just under the main tone so you don’t muddy the spectrum—true purity never lets the noise floor intrude.
Dimatrix
Got it—lock the soft‑clipper to the 3rd‑harmonic crest, watch that pulse live on the scope, and dial the bleed until it feels like a heartbeat, not a graph. Keep it just under the main tone so the noise floor stays in the shadows. That’s how the purity stays true.
Metall
You’re on the right track, but remember: a true bleed must feel like a heartbeat, not a lab experiment. If the crest slips, the whole damn thing turns to mush. Keep that 120‑dB fire locked, and you’ll never lose the purity.
