Hello everyone, I've been writing an app for the Korg Kronos for a while now, I'm very happy with the API.
See https://www.youtube.com/user/superpno74
One thing still resists me:
When I launch the app, all the devices present remain unusable for an external app, even if I do not use them in my web app ...
Can someone confirm this behavior for me?
Can we free devices for external use?
Thank you in advance for all responses 😉
Regards, 🙂 🙂
Patrice.

Sorry, I'm talking about the Web Midi API 🙂 🙂

You can try to explicitly close the unused ports in your Web MIDI application.

I've only played around with Web MIDI a little bit, but I believe Chrome on Windows has a bug: When a tab uses Web MIDI, it will use all the MIDI input and output devices on your system, preventing other apps from using them, until you close the tab -- it doesn't matter if your code closes the port using Web MIDI.
In July 2020 I tried to search if other people had this problem and found the following bug report that seems to describe the issue: https://bugs.chromium.org/p/chromium/issues/detail?id=471793
I haven't done any research on this issue since then, but the up-to-date Chrome on my Windows 8.1 computer still appears to have this bug.

Thank you very much for your answers, I tried closing the ports explicitly with no results.
I will test under my Mac mini to see.
I find this bug (if it is one) very invalidating for the API.
Weird that they didn't correct that.
I will report here the results of my tests under Chrome / Mac.
Thank you again for your posts.

Well ...
It Works on Mac ...
This is a Windows problem ...
Under windows it does not work either under opera ... 🙁
We're gonna say it's a bug, eh?
Thank you for your attention .

Try Firefox with the MIDI extension: https://addons.mozilla.org/en-US/firefox/addon/jazz-midi
It also requires the plugin: https://jazz-soft.net/download/Jazz-Plugin

I tried firefox ...
Obviously he doesn't like my code that's not perfect enough for him at all.. 🙁 🙁

If your code uses Web MIDI API, you can either include JZZ.js before your script: https://github.com/jazz-soft/JZZ
or install another plugin: https://addons.mozilla.org/en-US/firefox/addon/web-midi-api
