¿Can I touch key from any function or instruction?

[developez]

I would to ask if I can touch key programatically.

[felipefialho]

Uhmmmm

Maybe you can create a triggers to simulate click on keys...

[developez]

i am thinking to make chords programatically, do you think that is possible??

[felipefialho]

I think yes.

But I don't have imagined it when I've created this project.

[developez]

By the momento firing click does not work:

$($("li.key")[1]).click();

I suppose that to fire the event that plays the sound will be enough

[felipefialho]

The correct approach is

$("li.key:nth-child(2) > .black-key").trigger('click'); or $("li.key:nth-child(2) > .white-key").trigger('click');

[developez]

that sounds on you machine???

[felipefialho]

Not, it's weird.

I need to test again later.

Hello from France :)
You think about making chords, like this ? http://www.pianochord.org/

I would be very interested to. And I would be interested to contribute to it.
The other day, I just made a simple keyboard on my Codepen, but it isn't as good as yours.

Hi @aureliet. This is an old project (since 2013), but I want to update it.

I like any suggestion to improve piano and I am open to PR's accepts 😹

Thanks!

Hello @lfeh !

My code can be better, I think, but now we can have the chords.

Can I propose the app to a music school?
They won't pay me for it. Maybe one free piano lesson but that's all. They would be interested to use it on their website for their students.

Edit :
in the index.html :
Now we have data-number on the spans. From this, we can calculate the chords.
And we have two selects, to get the different chords variations.

in the _general.js :
The js I added to make chords

And... we will have to add notes, because from the A# to the end, we don't have enough...

For the problem I mentionned before, problem solved . Just change theses cases :

case "Add2" :
           note2 = note1+2;
           note3 = note1+4;
           note4 = note1+7;
           break;

       case "Addm2" :
           note2 = note1+1;
           note3 = note1+4;
           note4 = note1+7;
           break;

       case "Addm3" :
           note2 = note1+3;
           note3 = note1+4;
           note4 = note1+7;
           break;

Hey @developez, check if it works now?
