Component, not curve
We model what the hardware IS, not what it does. The physics is the algorithm - every transistor, tube, transformer core, and capacitor simulated as itself.
Many analog modeling plugins use "black box" modeling: measure what hardware does, build a filter that copies the curve. The curve is right; the behaviour underneath is wrong. The EQ doesn't know the compressor exists. The transformer doesn't remember the bass note from a moment ago. The circuit isn't a circuit - it's a chain of approximations pretending to be one.
Analog Realism began with a different premise. Model the components themselves - every transistor, tube, transformer core, capacitor and inductor - wired in the real circuit topology. Let the sound emerge from the physics, not from a hand-tuned curve. When the compressor works hard, current draw rises and the shared power rail sags, shifting the operating point of every other stage. The transformer remembers its recent magnetization history. The inductors saturate differently. Fifteen mechanisms acting as one circuit - like real hardware would.
This is TrueRail. It's not just a marketing word.
Our catalogue is deliberately small. We would rather build one product that lasts for years than ten products that need patching every quarter. The plugin runs no analytics and never phones home. If we close tomorrow, your tools still work tomorrow.
