HX3 Flash for OEMs

Information given here is intended for OEM use only.

Due to some demand I changed the HX3 Flash updater app behaviour.

Former versions of HX3 Flash looked what firmware was installed on the HX3 board and tried to determine what might be adequate to install. That often lead to unwanted results if parameters in new firmware changed significantly. Or I had a lot of work implementing minor parameter changes for various OEM *.hex files.

The new HX3 Flash is customizable by OEMs like you, so it might be completely adapted to your needs. You might prepare a package for your customers like the Flash_*.ZIPs on

containing only the necessary files for a specific instrument. The behaviour of HX3 Flash is controlled by an INI file named hx3_flash_config.ini which is human-readable and may be edited by a simple text editor. Content of INI looks like this example:

/ Configuration file for HX3 Standard Organ
/ Disable lines with comment char '/' at start
/ Extend to other parameters at own discretion

As you see, you can decide which buttons are enabled and which parameters have to be tweaked after firmware was installed. User Name and Licences are always retained.

Therefore, you may adjust parameters to your taste or to requirements of your instrument - without urging me to re-compile just for some parameter issues. All parameter numbers given in HX3 Remote pages are valid, so you may even change rotary params or MIDI CCs.
