Can't get MIDI IN to work (chrome 38) about midi-synth HOT 13 CLOSED

Hmm, strange. You shouldn't need the Jazz plugin, but it shouldn't harm anything either.

Can you open up the developer tools console and see if any warnings are firing?

from midi-synth.

No there's nothing in the console apart from the key logs and there is no text in the MIDI_IN select box on the synth.

from midi-synth.

Have you tried a more recent version? Could you install Chrome Canary alongside and check it?

from midi-synth.

Yes just tried in Canary and its not working either.

Looking at line 51 of midi.js: var list=midiAccess.inputs();
My list.length = 0. I'm guessing thats not right?

I have an Akai MPD & a yamaha keyboard plugged in and MidiKeys open just to check.

from midi-synth.

In Canary, you shouldn't get to that point. No, it shouldn't be 0, but
Canary shouldn't be dropping in to that clause, because it has the new
implementation of midiAccess - it should fail the test above

if ((typeof(midiAccess.inputs) == "function"))

and drop into the clause around line 70 instead.

What OS are you on?

Oh, guessing OSX from MIDIKeys. Hmm.

Apologies yes Canary does go down that route but it doesn't make it into the for loop on line 89.

I'm on OSX v 10.9.4

Weird. I'm guessing you've got an odd API in your build - I'll have to
look into it a bit more in a couple of days.

I just tested on my work computer (OS 10.9.5 & Chrome 38) and the midi synth worked!

It must be something to do with my machine. Do you think it would it help if I reinstalled chrome or perhaps there's an app running in the background that may be conflicting with it.

from midi-synth.

You have to enable the requestMidiAccess method in your chrome flags; Try to open chrome://flags/ and search for "requestMidi.." and press enable 😸

from midi-synth.

Should be fixed now.

Hi @cwilso, it's still not working for me. It detected that a keyboard was connected; 'KEYBOARD' in the select box, but pressing the keys didn't do anything. Then I disconnected the keyboard and refreshed the page multiple times and it still has 'KEYBOARD' in the select box (when no midi controller is connected).

@janbiasi I don't have a requestMidiAccess option in chrome flags. There's only an 'Enable Web MIDI API' which is activated.

@lukephills - I'm not sure what's going on. I'm not getting midi messages delivered in my current stable (42.0.2311.135) either; however, it works fine in Beta channel, and also in Canary. Try installing Canary and see if it works; Stable is going to 43 very soon.
