Freeshared rooms and live MIDI over the network - plug in a controller and play together from the browser.
P2P — WebRTC only, notes play on arrival. Hybrid — WebRTC with server fallback and buffered timing (best across cities / strict NAT). Server — hub relay only, buffered timing.
How it works
No installs, no DAW setup, no waiting — just plug in, open a room, and play together.
Hook up your keyboard or controller — the browser detects it.
One click and you have a jam space ready to go.
Share the link. When they join, you play together instantly.
That's it — you're ready to jam.
Quick answers for audio, MIDI, and connection issues people often hit when jamming in the browser.
WireChord sends MIDI over the network, not a microphone or audio recording of your instrument. What you hear in the browser is the app playing incoming MIDI from other musicians.
Your own keys are not played back in the tab—you hear yourself on your hardware or DAW. Your MIDI still goes to everyone else in the room.
Other players’ notes play in your tab after you’ve joined the same room and their MIDI is reaching the hub.
Browsers often block audio until you interact with the page (click, tap, or key press). After joining, click inside the tab once and try again.
Check system volume, the correct output device (Bluetooth vs speakers), and that the browser tab isn’t muted.
Confirm you’re in the exact same room name/code as your friends and that the SignalR hub URL is correct and reachable.
Use a browser with Web MIDI (Chrome or Edge on desktop work best). Safari and most mobile browsers have limited or no Web MIDI access.
Connect your keyboard or virtual MIDI port before or after opening the room; if nothing appears, unplug/replug or refresh once the device is connected.
If the browser asks for permission to use MIDI devices, allow it. Corporate profiles or strict privacy settings can block access.
The hub URL must match your backend (including https in production). A typo or wrong port is the most common issue when the URL isn’t pre‑configured in the environment.
The API must be running and reachable from your network. Firewalls, VPNs, or ad blockers can interfere with SignalR.
If you self‑host, check CORS and that the negotiate endpoint matches what the client expects.
The in‑browser synth is a simple monitor for jamming—it won’t match a hardware synth or DAW plugin.
Latency depends on network round‑trip, buffer sizes, and your audio device. Playing across continents will feel slower than on a LAN.
