Normally cmd 0x64 is used to upload a preset to the device, as per config file.
Malformed writes can corrupt presets, nothing is returned by keyboard crashes and preset is 'bad' on next boot/read
$ amidi -p hw:1,0,0 -S 'F0 47 00 26 64 00 01 00 F7' -r temp.bin
This appears to be the command to read back the presets (0x00=ram, 0x01..0x04), however note that 'cmd 0x67' is not the same as the official presets, and these don't upload with tweaking it to '0x64'
