CARBON Bootloader Installation for Windows 10 and macOS
The CARBON Bootloader released in 2019 allows the CARBON sequencer
to be updated using our new KAUpdate
Firmware Updater tool using WebMidi technology. No software or firmware files need to
be downloaded, simply visit the page and perform the installation.
We will explain the process for Windows 10, but the process for macOS is similar and
a bit simpler. (please see the macOS install video below) Please note that we no longer make updates for the tool used in this process
so you proceed at your own risk! If you can't make this tool work with your computer, try
another machine. As a last resort, we can arrange to install the update for you if you send
us your CARBON. We will install and test it free of charge. (you pay for shipping)
Note: Depending on your security settings it may be necessary to run these
programs as Administrator. On a default Windows 10 installation you should be prompted
when necessary, but if you have any trouble installing or running the software please
It might be necessary to agree to allow KAUpdate to control your MIDI ports -
you must agree to this for the web application to work
Hold the RUN/STOP and RECORD buttons on CARBON and plug in
the power cable - a red screen should appear
Plug in the USB cable from the PC to CARBON
Wait for the CARBON USB MIDI device to be detected and installed - Windows
should pop up a prompt when the device is ready to use
Select the latest CARBON firmware version from the Product Type
list in the KAUpdate page - keep track of the version number for later
Press the Rescan button
Select CARBON from the MIDI OUT and MIDI IN ports
Press the Update button and wait for the installation to complete
Unplug the USB cable and power cable from CARBON
Close the KAUpdate browser tab
Step 5 - Test the Result
Plug the power cable in to CARBON (not holding any buttons)
Power up CARBON using the power button
Hold SHIFT and press SYS - the version number shown on
the screen should match the version you just installed from the KAUpdate tool
For future updates, only steps 4 and 5 need to be completed
Enjoy your new firmware!
Installing CARBON Bootloader on macOS
Please check out the video below for instructions on performing this process
on macOS. This requires OS X 10.12 or later. The step-by-step process is the same
as for Windows 10 except that no device drivers need to be installed.
Computers can be funny, and unfortunately even clear step-by-step instructions
are not able to cover every possible scenario. Also USB is known to be finicky even
after all these years.
The most common problem with firmware updates and bootloader installation is that
either the USB device is not detected, or the application cannot see the device. Unplugging
and replugging the USB device, rebooting the device or PC, or trying different USB ports
are all known ways of overcoming problems. Unfortuantely low-level processes like firmware
updates are not often good at handling or recovering from errors. The best choice is to start over.
If you have issues with the device partially updating and then failing, there is most
likely another program or process interfering with the USB port. Perhaps the driver is not
fully installed, so just wait a moment before starting. Once again rebooting the PC and only
running the applications needed is usually the best way to ensure success.
Lastly, if you have tried everything and still can't get it to work, unfortunately
it might just be that your computer has some software or drivers which are preventing proper
operation. Trying the process on a different computer might help.
