For piano teachers and their students

For lessons
that keep teaching.

The call ends. The teaching doesn't. Duomidi records every lesson — every note, every correction — in perfect sync, so students practice with the real thing all week. Not notes scribbled on a page. The lesson itself.

§ 01 Why duomidi
01 — Every lesson recorded

The call ends. The teaching doesn't.

What you worked on today keeps working — tomorrow, and every day until the next lesson. Every session records itself the moment it starts — no button to hit — capturing the demo, the correction, the exact phrasing you fixed. Drills tied to that session, real feedback as your student practices, a shared record so the next lesson starts where this one landed, not where memory left it.

Replays into your student's piano — same notes, same touch — every day until the next lesson.
02 — Real-time MIDI

Two pianos, one keyboard.

Duomidi sends the notes, not the sound — so when one of you plays a phrase, the other feels it on their keys the instant fingers lift. Trade fours, play duets, demo and mirror in real time. No lag, no playing over a delay. And every bit of it is captured, exactly as it happened, for the week ahead.

03 — Easy setup

Less setup, more music.

Plug in your piano. Open your laptop. The lesson starts — hands and face on both ends, every nuance of touch intact. No mixer, no streaming software, no extra gear to begin. Want a second camera later? We'll help you set it up. The rig you've been hacking together — gone.

Required setup
  • Digital piano (any brand)
  • USB or MIDI cable
  • Laptop with Chrome / Edge / Firefox / Opera
  • Audio interface
  • Mixer / preamp
  • DAW / streaming software
  • DI box, lights, second screen
§ 02 How it works

We send the notes, not the sound.

Press a key, and your piano emits a tiny event — three bytes that say which note, how hard, how long. We capture that event the instant it leaves your instrument and forward it peer-to-peer to your partner, whose piano plays it. No audio compression, no jitter buffer, no waiting.
