What happens when you lock a pianist, a box of differential equations, and a deep love for acoustic resonance in the same studio? You get TopModel—a physical modeling synthesizer that behaves like real matter under tension.
TopModel VST3/CLAP UI — Exciter, Modal Resonator & Body Pickup sections
Rather than playing back lifeless samples, TopModel computes the physical vibrations of virtual strings, wooden soundboards, and metallic membranes in real time. Pluck it softly, and it purrs with warm cedar wood. Drive the exciter harder, and non-linearities take over: rattles, scrapes, harmonic bloom, and micro-chaotic grit.
Key Architecture
- Multi-Exciter Core: Hammer impulses, continuous bowing friction, plectrum strikes, and filtered noise burst generators.
- Dual Resonator Bank: Coupled wave-guide networks, modal comb filters, and sympathetic resonance emulation.
- 202 Factory Presets: From ethereal futuristic glass harps to monstrous prepared upright pianos.
- Open Source & Multi-Format: VST3, CLAP, and Standalone on Windows, macOS, and Linux.
