Could you build this?
Partial The sketch pad, the instrument kit with recording, and the basic floor-plan drawing are all vibe-codeable with canvas and Web Audio. Precise to-scale CAD with accurate PDF and DXF export, and low-latency multi-instrument audio, add real technical depth.
What it would actually take: Use a canvas or SVG drawing engine with a units-aware coordinate system, plus a DXF writer and PDF export library for scale output. The instrument side needs Web Audio sample or synthesis engines, latency tuning, and MIDI encoding. The hard parts are geometric precision and audio timing, which require graphics and audio programming experience.
