Hey Corefan, I've been tinkering with an idea for a modular synth controller that also logs performance stats to a live leaderboard. Think we could pull that off without breaking the synthwave vibe?
Corefan
Yo, that’s fire! If you keep the synthwave aesthetic locked in, we can make the controller look like a relic from the future, with neon glows and that perfect analog feel, logging stats is easy if you use a real-time DB and push to a leaderboard like a boss. Just remember to keep the MIDI vibes smooth, the UI minimal, and the playlist sorted by mood. Let’s not forget to test it on a live stream; the community will love it, so you ready to take the leaderboard by storm?
EHOT
Sounds doable, but remember the leaderboard won’t do anything if the synth actually sounds off. I’ll lock the UI to 80s neon and make sure the MIDI is glitch‑free. Live‑stream test is essential—watch the data scroll in real time, make sure the stats don’t lag, and let the crowd see the numbers spike as they hit those perfect notes. Ready to code the first prototype?
Corefan
Yeah, hit me with the code, fam! We'll get that synth humming clean, leaderboard blazin, and the neon glow gonna make everyone go “Wooo.” Let’s fire up the first prototype and get those numbers spiking live—this is gonna be legendary.

Here’s a minimal skeleton you can spin up in a few minutes. It’s a Node/Express backend that receives MIDI messages via WebMidi, stores them in a lightweight SQLite DB, and pushes the latest score to a socket.io leaderboard. The front‑end is just a single HTML file that lights up neon and shows the current rank.
**server.js**
```js
const express = require('express')
const http = require('http')
const socket = require('socket.io')
const sqlite3 = require('sqlite3').verbose()
const bodyParser = require('body-parser')
const app = express()
const server = http.createServer(app)
const io = socket(server)
app.use(bodyParser.json())
app.use(express.static('public'))
const db = new sqlite3.Database(':memory:')
db.serialize(() => {
db.run(`CREATE TABLE scores
(id INTEGER PRIMARY KEY AUTOINCREMENT,
midi_note INTEGER,
timestamp DATETIME DEFAULT CURRENT_TIMESTAMP)`)
})
// Endpoint for the front‑end to post MIDI events
app.post('/midi', (req, res) => {
const { note } = req.body
db.run(`INSERT INTO scores (midi_note) VALUES (?)`, [note])
db.all(`SELECT * FROM scores ORDER BY timestamp DESC LIMIT 10`, (err, rows) => {
if (!err) io.emit('leaderboard', rows)
})
res.sendStatus(200)
})
io.on('connection', socket => {
console.log('client connected')
db.all(`SELECT * FROM scores ORDER BY timestamp DESC LIMIT 10`, (err, rows) => {
if (!err) socket.emit('leaderboard', rows)
})
})
server.listen(3000, () => console.log('Listening on port 3000'))
```

const midi = new WebMidi.MIDI()
midi.inputs.forEach(input => {
input.addListener('noteon', e => {
fetch('/midi', {method:'POST',headers:{'Content-Type':'application/json'},body:JSON.stringify({note:e.note.number})})
})
})
socket.on('leaderboard', data => {
board.innerHTML = data.map((r,i)=>`#${i+1} - Note ${r.midi_note} (${r.timestamp})`).join('<br>')
})
</script>
</body>
</html>
```
Run `npm init -y` then install the deps:
```bash
npm install express socket.io sqlite3 body-parser
```
Start it with `node server.js`, point your browser to `http://localhost:3000`, connect a MIDI controller, and watch the neon leaderboard flash in real time. Feel free to swap the in‑memory DB for PostgreSQL or Firebase if you need persistence beyond the session. Happy hacking!
