In order to update the firmware for your controller you will need to download the Firmware loader for your OS:
In macOS you only need to drag the file to your Applications folder.
Then, you’ll need the firmware files.
Yaeltex controllers in its beta version have 2 firmware files:
- MAIN: Firmware for the main microcontroller. This one reads all the inputs and handles USB/MIDI communications.
- AUX: Firmware for the auxiliary microcontroller that controls LEDs.
Eventually you will only need a zip file! We’re working on it.
You can always find the latest firmware on our Gitlab page, inside the binaries folder. We’ll also post the updates in the Update log category in this forum.
Download the ytx-v2-firmware files corresponding to the version you want to use.
Open the application, and select the MIDI port from the list.
Choose the port that matches the name of your controller and press OK, and then you should see a message that tells that either the connection was made correctly, or that it failed. If it fails (typically in Windows) the port might already be taken by another application, so make sure to close every application that might be using your MIDI ports, i.e. Kilowhat or a MIDI monitor.
When it succeeds to open the port, it will automatically reboot your controller to bootloader state (you will see some colors cycle on the Yaeltex logo), and set it ready to receive a new firmware. You will see the Device: KilomuxBOOT text in green when all is set.
If you only see the Device: None, try restarting the YTX Firmware Updater app.
Now you can press one of the buttons to upload the MAIN firmware or the AUX Firmware.
Choose the right firmware file and press OK to send it to your controller
You will see a progress bar and when it completes the controller will be restarted and ready to go!
NOTE: Updating a firmware won’t erase your Kilowhat configuration
If by any chance, after a firmware update you don’t see your controller listed as a USB device anymore, we set a hard entry to the bootloader.
For this you’ll need a MIDI cable. Hopefully you have one of those, and if you don’t, there is still a way to make it work: Wired way to enter force bootloader entry
Steps for this are:
- Unplug USB.
- Plug the MIDI OUT port to the MIDI IN port with a DIN5 MIDI cable. If you don’t have a MIDI DIN5 cable, it’ll be a little harder, but it can be done. You’d need to wire like in the picture linked above, both pins 4 and 5 on the MIDI OUT connector to its matching pin on the MIDI IN connector.
- Plug the USB, and you should see that the status LED cycles through different colors. This indicates bootloader mode is active.
- You should see the green “KilomuxBOOT” label in the firmware loader app.
- Send the firmware to the controller.
