Atoms: Physical Modeling Synth Plugin by Baby Audio Free Download

Atoms runs a mass-spring simulation triggered by a virtual bow. The Force control sets the pressure of the bow on the springs, adding noisiness and sharper harmonics as it rises. Overtones moves the bow position along the network, changing how bright the result sounds. Order increases damping, which works much like a low-pass filter, and Chaos adds nonlinear pitch glides and detuning.

Attack and Release also come from the physics of the model. Attack changes how the bow starts, from abrupt to gradual, while Release controls damping, from short decay to near-infinite sustain. The Visualizer shows the nodes and connections in the simulation, so you can watch the network respond as you play.

Atoms includes a randomization engine that adjusts each parameter based on its relationship to the others. You can limit random ranges for any knob or lock parameters so they stay fixed. The Recycle button generates new patches similar to the current one, which is useful once you have a starting sound you like.

Besides Space, which is a reverb with size and mix controls on an X/Y pad, the bottom-panel effects are created by altering the physical model itself rather than adding a separate FX chain. Four sonic profiles offer different calibrations of the simulation, and the built-in resonant low-pass filter can be automated for LFO sweeps.
