I don’t have a connection cable yet. Which one should I choose?

There are two types of cables depending on your piano model. Check the connections on the back of your keyboard and choose the appropriate cable:

The MIDI-USB cable

Equipped with a circular connector, this cable adapts to certain types of pianos.


The printer type cable

It is the most used connector on digital pianos. You have a printer at home? Its cable will do the trick!


How do I connect my piano to the app?

1 – Go to one of the two following browsers: Google Chrome or Opera (connecting your piano to the platform will not work on other browsers).

2 – When you arrive for the first time on the learning interface, you have to authorize the browser to connect your midi devices (for more information, see the section “MIDI authorization on the browser” above).

3 – Make sure that your digital piano is equipped with MIDI connectivity.

4 – Take your MIDI-USB cable: plug the MIDI connector of the cable into the MIDI jack of your piano, then plug the USB connector into the USB jack of your computer. The application does not yet work well on mobile and tablet, we are developing a mobile application that will be released in the coming months. In anticipation of the release of this mobile application, please note that adapters exist to connect your mobile or tablet to your piano (where can I buy an adapter for mobile phone and tablet?).

5 – Go to the learning interface of the application: press a key on your piano, the same key lights up on your piano on the screen, you are well connected to the application! You can now use the interactive game modes and learn at your own pace.

Why is my piano not recognized by the app (orange connection light)?

When you first arrive on La Touche Musicale, your piano may not be recognized by the app. Indeed, when you connect your keyboard to the USB port of your computer, it sometimes happens that the connection icon located at the bottom right of the interface does not light up green, but remains orange connexion-piano, as this example:

The connection light is orange: the piano is not recognized by the app.

In this case, it means that the platform does not recognize your piano.

But don’t panic! This happens often. To solve this problem, check the following:

On iOS, the piano connection is not recognized.

The connections of your cable

If you have a MIDI cable (this does not apply to printer-type cables, which have only one connector), make sure that it is properly connected to your piano as follows: the “IN” of your cable in the “OUT” connector of your piano. The reverse is also correct: the “OUT” of your cable in the “IN” connector of your piano. If you connect the “IN” of your cable into the “IN” connector of your piano or, conversely, the “OUT” of your cable into the “OUT” connector of your piano, the connection will not work.

The connections must be reversed: the "IN" in the "OUT" or the "OUT" in the "IN".

MIDI authorization on the browser

The first time you arrive at the learning interface, a notification from the browser asks you to allow the MIDI connection. If you have inadvertently clicked “Block” (this happens often), the browser cannot connect your piano. To make sure that you have authorized the MIDI data, check in the search bar of your browser that you have a piano icon without a red cross on it. If you have a red cross on the piano icon like this one icone-google-chrome-pas-de-connexion-piano, this means that you have inadvertently blocked them, as in the following case:

Piano icon with a red cross: midi data has been blocked on the browser.

If you find yourself in this case, here are the 4 actions to perform to re-authorize the midi data on the browser [The following tutorial has been performed on the Google Chrome browser and may be different on other browsers] :

1. Click on a song in your dashboard (any song) and click on the small piano icon with a red cross in the search bar of your browser :

Step 1: click on the piano with the red cross to manage the browser permissions.

2. A message appears next to the piano icon: now click on “Manage” :

Step 2: click on "Manage" to open the permission management window.

3. The browser opens a new window: look where “app.latouchemusicale.com” is located (normally in the “Block” section) and empty your authorization data on this website by clicking on the trash can located to the right of the link “https://app.latouchemusicale.com” :

Step 3: Click on the trash can to reset the permissions on The Music Key.

4. Once the data is cleared, return to the La Touche Musicale window that is still open, and reload the page. A message appears in the top left corner of the interface: now click on “Allow” :

Step 4: reload the page and allow the browser to process the midi data.

Once you have authorized the browser to use midi data, you won’t need to do it again and will be able to directly connect your piano during your next sessions on your La Touche Musicale account.

The driver of your keyboard

In order for your piano to be recognized by the computer, you may need to install an installation driver (or “driver”) specific to the piano model on your computer. This is becoming increasingly rare because today’s pianos have built-in drivers, but it can still happen, especially on older models. This driver will always be available on the manufacturer’s website (Yamaha, Korg, Roland, Casio, Kawai, …). Get the user manual of your piano model (very often downloadable from the internet) for more information.

Tip: you can find the driver for installing your piano fairly easily on the internet by typing on Google the brand and model of your piano followed by “driver” or “installation driver”. Prefer the drivers offered on the official website of the manufacturer of your piano brand.

The cable of your piano

Make sure that your piano’s MIDI connection is connected to your computer via USB and that the hardware is still in working order.

My piano is recognized but nothing happens (green connection light)?

You have successfully connected your piano and it is recognized by the platform. You have the connection light which has turned green voyant-vert-piano-connecter, but nothing happens when you press the keys on your piano?

This is most often due to two problems: 

Multiple devices detected on your computer

Sometimes your computer may have several peripherals at the same time. Most often, this is an internal device in your computer, such as your sound card. The Music Key then automatically detects it as the first device connected and confuses it with the piano. This happens frequently on systems like Linux (Ubuntu).

That’s why we have set up on The Music Key the possibility to choose the device that will be detected by the platform. This possibility only occurs when several devices have been detected simultaneously on the platform.

To change the device and choose your piano, you just have to :

1 – Go to your La Touche Musicale account and click on a music (any one).

2 – Once on the learning interface, connect your piano: the connection light located at the bottom right of the interface should light up green.


Once the piano is connected, the app recognizes it and the connection indicator lights up green.

3 – Click on the connection indicator: a popup appears in the center of the interface.

4 – In this popup is present the sentence “Change device” (provided that The Music Key detects several devices on your computer, otherwise this sentence is not present), next to which are arrows to change device. Click the arrow and choose your piano.

Device change appears when more than one device is detected on your computer.

5 – La Touche Musicale will then detect the device concerned by your piano. You can now interact with the app and learn at your own pace!

The connections of your cable

This has already been mentioned above, but sometimes this problem also occurs when your green connection light is on.

If you have a MIDI cable (printer-type cables are not affected because they have only one connection), make sure that it is connected to your piano as follows: the “IN” of your cable in the “OUT” connection of your piano. The reverse is also good: the “OUT” of your cable in the “IN” connector of your piano. If you connect the “OUT” of your cable into the “OUT” connector of your piano or, conversely, the “IN” of your cable into the “IN” connector of your piano, the connection will not work.
