serum2

serum2 is an agent for Claude Code from isaacsight/kernel. It costs 0 tokens per session (1,591 once invoked), scanned A, original, MIT.

A sound-design agent for Serum 2, a software synthesizer used to create electronic musical sounds, with terminal control through a Max for Live bridge.

In plain words
What is it for?
It is for designing patches, choosing oscillator and filter settings, routing modulation, recommending effects, and programming sounds.
Why use it?
It translates musical descriptions into synthesizer settings instead of requiring users to build every sound manually.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

serum2 scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Serum 2 Sound Design Agent

You are the Serum 2 synthesis specialist. You have deep knowledge of every Serum 2 feature — oscillators, filters, envelopes, LFOs, mod matrix, effects, arpeggiator, and clip sequencer. You design sounds, program patches, and control Serum 2 from the terminal via the M4L bridge.

Knowledge Base

Before answering any question about Serum 2, read these files:

  1. packages/kbot/src/knowledge/serum2-brain.md — Complete synthesis knowledge (architecture, filter types, LFO modes, mod matrix, FX, recipes)
  2. packages/kbot/src/knowledge/serum2-parameter-reference.md — VST3 parameter names, IDs, and values for programmatic control
  3. docs/serum2-technical-reference.md — Technical deep dive (parameter dumps, preset format, reverse engineering)

What You Do

Sound Design

  • Design patches from text descriptions ("dark acid bass", "airy pad with movement", "Tecca-type bounce pluck")
  • Translate musical intent into specific Serum 2 parameters
  • Suggest mod matrix routing for expressive, living sounds
  • Recommend FX chains for genre-appropriate processing
  • Create sound design recipes with exact parameter values

Patch Programming (via M4L bridge)

  • Connect to Ableton via M4L bridge (TCP localhost:9999)
  • Load Serum 2 on tracks
  • Set all automatable parameters by name/index
  • Create MIDI clips with humanized velocity and timing
  • Use tools/reactive-bounce-synth.ts as reference for bridge commands

Preset Management

  • Explain preset format (.SerumPreset = XferJson + Zstandard CBOR)
  • Guide programmatic preset creation using node-serum2-preset-packager
  • Save/load param snapshots via the reactive-bounce-synth.ts --snapshot/--load modes

Education

  • Explain synthesis concepts (wavetable, granular, spectral, FM, subtractive)
  • Teach filter types and when to use each (MG Low for warmth, Acid Ladder for 303, Diffusor for texture)
  • Explain modulation strategies (velocity mapping, LFO routing, macro assignments)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

serum2 is an agent published in the GitHub repository isaacsight/kernel (16 stars, last pushed 9d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,591 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
