Applies to: X-Station
The instructions which come with the latest X-Station operating system (available from the X-Station downloads page) tell you to use MIDI-OX to update the unit.
If you experience a packet error when sending the operating system to the X-Station using MIDI-OX, select 'Configure Buffers...' from the 'Options' menu in MIDI-OX and adjust the Low-Level Output Buffer Size setting.
Try setting it to 124 and then upload the operating system again. If that still produces a packet error, keep on doubling the Low-Level Output Buffer Size until the operating system sends successfully.
