Description
A semi-modular monosynth in a browser tab: two anti-aliased oscillators, two Sallen-Key filters, two envelopes, a mod generator and an external signal processor. The 35-socket patch bay is the point. You drag real cables, and plugging one in OVERRIDES the normalled default rather than adding to it, which is what makes a semi-modular a semi-modular and what browser synths usually skip. 35 factory patches, MIDI in, shareable patch links, a printable patch sheet. Free, no account, no install.

Could you build this?
Partial While browser UI and basic Web Audio nodes are easy, custom DSP for anti-aliased oscillators, Sallen-Key analog filter modeling, and a 35-socket modular normalling routing matrix require solid audio DSP knowledge.
What it would actually take: To build this, use the Web Audio API with custom AudioWorklet processors written in C++/Rust compiled to WebAssembly. The hard part is writing the numerical simulation for the non-linear Sallen-Key filters and band-limited/anti-aliased oscillators (BLEP/BLAMP) without introducing audio artifacts or phase issues. Front-end cable patching can be managed with SVG/Canvas and reactive state mapping.
