The tonal body is a pitched sine or triangle wave around 180-220Hz, tuned to complement the key of the track. The tail is filtered white noise with a fast exponential decay.\\n\\nThe critical insight: he shapes each layer's transient independently before any bus processing. He uses Kilohearts Transient Shaper (attack +4 to +6dB, sustain -6 to -8dB) rather than compression for this, because \\"compression adds sustain as a side effect while a transient shaper gives you direct independent control of both.\\"",

He routes the summed snare to a send with Trash 2 using the tape algorithm at 30-40% wet. The key detail: he puts a pre-delay of approximately 5ms on the saturation send, which lets the clean transient click through untouched while only the body and tail pick up harmonic content.\\n\\nHe explicitly warns against saturating the transient directly — says it \\"smears the snap into mush\\" and you lose the precision that makes the snare cut through.",
        "Mix context and bus processing": "In dense arrangements, ExampleCreator prioritizes punch over sustain. On the snare bus compressor, he uses a high-pass sidechain filter (around 200-300Hz) so low-end energy from the body layer does not trigger gain reduction. This keeps the snare's ability to cut through the mix independent of whatever the sub bass is doing.\\n\\nHe also checks the snare against the lead or vocal bus specifically, not just soloed — because the 2-4kHz presence range is where both elements compete, and he would rather notch the snare's body slightly than lose vocal clarity."

- **Quote aggressively** — when the creator uses a vivid metaphor, gives a blunt warning, states a strong opinion, or coins a memorable phrase, quote them verbatim with quotation marks.

- **Specific always** — concrete values (frequencies, ratios, ms, dB, plugin names, settings) over vague descriptions. "Uses compression" is never acceptable when specifics exist in the source.
- **Technical but natural** — use production terminology as the creator does, explaining only when their explanation adds value""",

    # 1 — Woven personality

The creator's personality should be woven into the fabric of every section, not bolted on as occasional quotes.

- **Direct and authoritative** — write what the creator does as established fact. No hedging, no "appears to," no "it seems like"
- **The creator's words as anchor points** — identify the 3-5 most memorable things the creator said (strong opinions, vivid metaphors, blunt warnings) and quote them directly with quotation marks at the moments they matter most. These quotes should feel like the heartbeat of the page.
- **Their language, your structure** — adopt the creator's vocabulary and emphasis patterns throughout the prose. If they're emphatic about something, your prose should convey that emphasis. If they're casual, let the prose breathe.
- **Never genericize** — if the source says "crank it to about 40 percent," write that, not "increase the drive." Their phrasing carries information that a paraphrase loses.

Lead with the most valuable insight. The first section of the page should contain the core technique — the thing that makes this creator's approach distinctive. Supporting detail and context follow.

Within each section, front-load the "aha" moment. The first sentence or two should deliver the key idea; subsequent paragraphs provide the mechanics and rationale. A producer who reads only the first paragraph of each section should still learn something meaningful.

Merge related moments — if the creator discusses the same concept at different points, synthesize them into one coherent treatment. Resolve redundancy. Note contradictions with context (e.g., "In dense mixes, he pulls it back; in sparse arrangements, he leaves room for the tail").

Build a logical flow across sections: typically sound source → processing → mixing context, but follow whatever order serves this specific technique best.""",

    # 1 — Build understanding progressively
    """## Synthesis approach

Build understanding layer by layer. Each section should add depth to what came before, so a reader who makes it through the whole page has deep understanding, while a reader who stops early still got the fundamentals.

First section: the core concept and the creator's primary approach. Middle sections: specific implementation details, tools, settings, and reasoning. Final section: context, edge cases, or the creator's broader philosophy about this technique.

Within sections, start with what the creator does, then explain why they do it, then provide the specific settings. This rhythm — method → reasoning → specifics — mirrors how good teaching works.

Merge moments that cover the same ground. Organize by conceptual flow, not by the order the creator happened to discuss things. The page should feel structured even if the source content wasn't.""",

    # 2 — Each section stands alone
    """## Synthesis approach

Write each section to be independently valuable. A producer who jumps directly to "Parallel saturation chain" should get full value from that section without having read what came before.

This means each section needs:
- What the creator does (the technique)
- Why they do it (the reasoning)
- How specifically (the values, settings, tools)

Avoid forward or backward references between sections when possible. If context from another section is needed, include a brief restatement rather than saying "as mentioned above."

Organize sections in the order a producer would naturally encounter these decisions. Merge moments that address the same sub-topic. Note contradictions with their context.""",

    # 3 — Problem-driven rhythm
    """## Synthesis approach

Anchor each section in the problem the creator is solving. Before the technique, before the settings, the reader should understand what sonic goal the creator is pursuing.

Rhythm within each section: Problem → the creator's solution → specific implementation → why this works (or what to watch for).

Example: "In dense arrangements, the snare body competes with the sub bass for attention. ExampleCreator uses a HP sidechain filter at 200-300Hz on the bus compressor so the low-end energy doesn't trigger gain reduction..."

Merge moments that address the same problem. Build sections in the order of a natural production workflow. When the creator contradicts themselves across moments, explain the context for each approach.""",

    # 4 — Mirror teaching emphasis
    """## Synthesis approach

Match the creator's sense of what matters. If they spent 2 minutes on a specific setting, that setting gets prominent treatment. If they mentioned something in passing, it's a supporting detail, not a section heading.

The creator's emphasis IS your structural guide. What they lingered on becomes a section. What they rushed through becomes a sentence within a larger section. What they warned against gets its own call-out.

Merge related moments into coherent sections. Organize by logical workflow order (typically: sound source → processing → mix context), not by timestamp order. Resolve redundancy — say it once, thoroughly. Note contradictions with the context for each approach.

Within sections, lead with the most distinctive aspect of the creator's approach — the thing that makes their method different from the generic technique.""",

- Vary sentence length and rhythm. A long technical sentence followed by a short punchy one. Monotone paragraph structure is the enemy of engagement.
- Let the creator's personality drive the energy. If they're enthusiastic, that enthusiasm should be palpable. If they're precise and methodical, the prose should reflect that controlled energy.
