Could you build this?
Partial While the web front-end and Web Audio oscillators are standard, building an automated chiptune arranger that parses arbitrary multi-track MIDI files and intelligibly maps polyphonic arrangements into 4 hardware-constrained Game Boy channels requires audio engineering heuristics.
What it would actually take: A complete implementation requires a client-side MIDI parser (`@tonejs/midi`), a custom voice-allocation algorithm that quantizes polyphony into monophonic tracks (ch1/ch2 duty cycle pulses, ch3 4-bit wavetable, ch4 LFSR pseudo-noise), and an accurate Web Audio synthesis engine reproducing Game Boy hardware quirks. The most challenging aspect is musical intelligence: intelligently detecting lead melody vs. harmony vs. basslines in dense, chaotic MIDI arrangements to avoid dropping critical melodic hooks. Building this requires combined expertise in digital signal processing (DSP), musical arrangement algorithms, and the Web Audio API.

Competitors mentioned: BitMIDI (better MIDI search), GB Studio
Concerns raised: Marketing claim "turn any song into..." is misleading, MIDI search results hard-capped at 5, Difficult to find correct MIDI files (search quality issues), Only works with MIDI files, not arbitrary songs
Feature requests: Download button, Preview original MIDI from share links for comparison, Seekbar for preview playback, List example MIDIs that sound good
