1. Important
To update the HX3.5 to the new firmware generation 5.6, a Windows 10 PC is best suited.
Please note section 2. Driver Installation when using older Windows versions.
Due to the extensive structural changes, existing presets are unfortunately not retained if
they were created with firmware versions prior to 5.30 The update procedure takes about 25
minutes. Connect your HX3.5 device or HX3.5 motherboard via USB and start the HX3.5
Updater. Click on Connect.
When the connection is established ('MIDI' is highlighted in green), select the desired
configuration of your device in the dialog box on the right. Click on the Update! Button. A
dialog box now reminds you to unplug the MIDI cables. This is absolutely necessary!
The first step is to update the DSP firmware. To do this, the HX3 system is put into DFU
transmission mode. Windows requires a driver for DFU communication, which may need to
be loaded and installed first (see section 2. Driver Installation for older Windows systems).
The DREAM Updater for the DSP starts. DSP update is essential for the next update steps in
HX3.5 Updater, so make sure the DSP firmware is properly installed. Select the update file,
"HX35_5504-FW_0119.dfu" and click on Update Device. After the update, terminate the
DREAM Updater with Abort.
During the update, the automatic procedure is controlled by a script. To protect the update
against transmission errors, all data is first loaded into a cache and checked. Only when the
integrity is established, data is transferred to the destination.
If a transmission error is reported, restart the HX3 system by momentarily disconnecting the
power and repeat the procedure. If errors occur during further attempts, please contact
info@keyboardpartner.de. Please specify the device configuration as exactly as possible.
After the update, the 'Board Info' will appear with all new version numbers in the Log
Window.
Note for SD card updates: HX3.5 Editor directory will contain several .BAT batch command
files to create customized SDCARD folders (in case you want to use the SD card update
feature). Just double-click the matching "make_sdcard_xxx.bat" file for your product and
copy content of SDCARD folder to your SD card root directory.
Please also read also the new manual. A lot has changed.
