<h4>What is this?</h4>
<p>A hobby project exploring <strong>MIDI → retro synthesis</strong>. Search a song, preview its MIDI, then generate a chiptune-style variation.</p>
</div>
<div class="faq-item">
<h4>How was it built?</h4>
<p><strong>Vite + TypeScript</strong> frontend using <strong>Web Audio</strong> (procedural synth) plus a <strong>Soundfont</strong> piano preview. Backend is a small <strong>Express</strong> API (search/fetch/parse) deployed on Vercel.</p>
</div>
<div class="faq-item">
<h4>Why do I need “Enable Audio” on iOS?</h4>
<p>iOS Safari requires a user tap before audio can play. Tap <strong>Enable Audio</strong>, then press <strong>Generate &amp; Play</strong>. If it’s still silent: disable Silent Mode / raise volume / disconnect Bluetooth.</p>
</div>
<div class="faq-item">
<h4>How can we develop it further?</h4>
<p>Add more MIDI sources, better matching, and style presets (ambient / dance / ominous). Then ship a compact <code>/embed</code> widget and an SDK so other sites can drop in “pixelised music”.</p>
