Updating the firmware

Start firmware update
as the bootloader can only read FAT32 filesystems.
 * Get the latest firmware version: http://forum.sonic-potions.com/discussion/29/latest-firmware-version#Item_20
 * Make sure your SD card is using FAT32! Otherwise you will get a “Firmware error” message,
 * Copy the 'FIRMWARE.BIN' file to the SD cards root directory.
 * Insert the card into the turned off LXR.
 * Push and hold the encoder, then turn on the synthesizer.
