Console Summing System
Iron Summing
The console, reassembled.
A paired Channel and Bus system. Channel instances expose track-side tone and grouping controls; the Bus exposes the summed controls and a registry view of participating instances.


Signal path
Why it exists
Place Channel instances on tracks, assign their group and channel controls, then use the Bus role for its summed controls and the registry view. The instances coordinate control state; they do not route audio between plugins.
Channel and Bus
Two roles, one visible registry.

01 · Bus
Bus role.
The Bus surface exposes its summed controls and the participating-instance registry.
02 · Channel
Channel role.
Channel instances expose track-side tone, group and related controls.
03 · Flood
Flood control.
The deterministic Flood state proves the control on the real Bus interface.
Where it earns its keep
Built for the jobs you actually have.
Track channels
Use the Channel role for track-side tone and group controls.
Summed bus
Use the Bus role for its own EQ, Push, Flood, width, space, mix and output controls.
Grouped control
Use the source-defined group selection and registry to organize instances.
Session visibility
Read participating instances from the Bus registry without implying cross-instance audio routing.
What's in the unit
Real pixels, not promises.

Bus
The Bus role and registry in the real interface.

Channel
The Channel role and its track-side controls.

Flood
The Bus shown with Flood active as deterministic proof.
What is measured, not promised
| Claim | The number | How it is held |
|---|---|---|
| Transformer harmonics | H2 near -55 dB at 50 Hz, below -100 dB at 1 kHz, at Tone 100 | Automated harmonic measurement per release |
| Glue cap | GR can never exceed 3.0 dB; Flood lift mirrors to 0.01 dB | Asymptotic curve, measured worst case 2.999 dB |
| Transparency | Bit-exact at Tone 0; nothing random between recalls | Null-test reference preset ships in the box |
| Aliasing | Products below -80 dB at 44.1 kHz at full drive | Measured worst case -85.2 dB |
Everything in the box
- Channel and Bus roles
- Channel group selection and track-side controls
- Bus instance registry
- Bus EQ controls
- Push and Flood controls
- Bus width and space controls
- Mix and output controls
- Control-state coordination without inter-instance audio routing
Specifications
Questions engineers ask
What are the two roles?
Channel for track instances and Bus for the summed controls and registry view.
Does audio move between plugin instances?
No. The shared registry coordinates control state; each instance still processes its own host audio path.
What does the Bus expose?
Its current source includes EQ, Push, Flood, width, space, mix, output and the participating-instance registry.
