আপনার MIDI ডিভাইস কাজ করছে?
Detect connected MIDI instruments and controllers, view real-time MIDI messages, and verify that note, control, and pitch data are received correctly — all in your browser.
This tool uses the Web MIDI API to enumerate connected MIDI input and output devices, display their names and manufacturers, and visualize incoming MIDI messages (note on/off, control change, pitch bend) in real time.
The MIDI protocol has remained virtually unchanged since 1983, operating at 31.25 kbaud. MIDI 2.0 was ratified in 2020 with higher resolution (32-bit vs 7-bit values) and bidirectional communication.
No MIDI devices detected.

সাধারণ সমস্যা এবং সমাধান
No MIDI devices appear in the list
Ensure your MIDI device is connected via USB (or USB-MIDI adapter for 5-pin DIN connections) and powered on. On macOS, check Audio MIDI Setup. On Windows, check Device Manager for MIDI devices. Try unplugging and reconnecting.
Device is listed but no MIDI messages appear when playing
Verify the MIDI device is set to transmit on a channel the tool is listening to. Some controllers have a 'Local Off' setting that prevents MIDI output. Check your device's configuration and ensure it is not in a setup or programming mode.
