Same DSP truth as native. The kernel runs the same core/signal C++ node classes native Pulp plugins ship — bit-exact to a compiled build (S0: maxAbsDiff = 0).

Your last valid patch keeps playing. Break the code and the sound continues while the error underlines — audio is never silenced.

Not a compiler pitch. A live patch language for Pulp's DSP primitives, parsed and hot-swapped client-side in milliseconds. MIT, open source.
