When the Nixie software first detects a pedal that requires a firmware update for compatibility with Nixie, you will be prompted to update the firmware. Download Nixie here.
To check for available firmware updates at any time for a pedal connected to Nixie, select Firmware Update from the Device menu. If multiple pedals are connected to Nixie, this will be the pedal with device focus.
NOTE: Clicking Firmware Update will erase all items from the History Pane for all currently connected pedals. An Auto Save for each pedal will be automatically created in the Preset Collections window. The Auto Save includes all changes that have not yet been written to the device, but will not include the undo history.
