About
Duet Stream is a specialized video conferencing tool designed specifically for musicians and music educators who need more than a generic video call. Unlike Zoom or Google Meet, Duet enriches remote sessions with music-centric features: connect a MIDI keyboard or digital piano, visualize the notes you play in real time, and instantly share that visualization with everyone else in the session. The platform includes built-in playable piano sounds so participants without physical instruments can still join in, and a shared metronome keeps everyone in sync during practice or performance. MIDI input support means any USB or MIDI-connected keyboard can be used straight from the browser without additional software. Duet operates on a freemium model: a free tier allows unlimited sessions of up to 20 minutes, ideal for casual lessons or quick rehearsal check-ins. The Premium plan extends sessions to four hours, making it suitable for extended lessons, masterclasses, or full rehearsal blocks. The tool is aimed at piano teachers running online lessons, students taking remote instruction, and musicians who want to collaborate across distances without sacrificing the visual and interactive feedback that in-person playing provides. Being entirely browser-based, it requires no downloads or installs, lowering the barrier for students and collaborators of all technical levels.

Pros
- Purpose-Built for Musicians: Unlike general video tools, every feature — MIDI sharing, piano sounds, metronome — is tailored specifically for music education and collaboration.
- No Download Required: Entirely browser-based, so students and collaborators can join a session instantly without installing any software.
- Free Tier Available: Unlimited free sessions (up to 20 minutes each) make it accessible for casual lessons or short practice check-ins at no cost.
Cons
- Free Tier Session Limit: The free plan caps sessions at 20 minutes, which may be too short for full music lessons or extended rehearsals.
- Niche Audience: The tool is purpose-built for musicians, so it offers little value to anyone outside music education or remote musical collaboration.
- Currently in Beta: As a beta product, Duet Stream may have limited features, occasional bugs, and a smaller user community compared to mature platforms.
