Subharmonicon Firmware Update Troubleshooting

Modified on Thu, 29 Jun, 2023 at 3:09 PM

If you are having trouble updating your instrument, please consider the following points: 


• Verify that you have as direct a connection as possible to your computer; avoid USB hubs, MIDI Thru boxes, or other MIDI devices/instruments before connecting Subharmonicon.


• Check the preferences section of your SysEx program and look for transmit speed. If your SysEx program allows, adjust this down to 50%.


• Begin each attempt from the beginning by sending the Invalidate file. Only load and send one file at a time.


• Lastly, you may find it helpful to re-establish the connection to your SysEx handler before sending each file in the process. For example, load and send Invalidate, close and reopen your SysEx handler, load and send Erase, close and reopen your SysEx handler, then load and send the firmware file.
