Special Error/Blink Codes

In normal operation, including a firmware update via MIDI SysEx message, none of the below errors will ever occur (except for Programming Finished)... but things might go wrong on very very seldom occasions.

These are unrecoverable but mostly non-persistent errors in general, the device is temporarily not operational after an incident. The device must be fully unplugged to reset and return to normal operation.

The LED indicator patterns are meant for post-mortem diagnosis, so please write down the colors and blink states should you ever run into such an error. The blink rate is very fast.

First LED Second LED Meaning
GREEN blinking GREEN blinking Programming Finished Successfully (NO ERROR)
WHITE WHITE (blinking or not) Severe Code Error (Lock-Up) *)
RED RED blinking USB Packet incorrect size
RED YELLOW blinking Unexpected USB Packet
YELLOW RED blinking SysEx Data Error
YELLOW YELLOW Waiting for SysEx End Marker
Magenta RED blinking Programming: Data is too large
Magenta GREEN blinking Programming: Data Length is zero
Magenta BLUE blinking Programming: Erase failed **)
Magenta MAGENTA blinking Programming: WritePrepare failed **)
Magenta WHITE blinking Programming: Write failed **)

*) Software Bugs as well as Broken Code (for example from an update gone wrong) will often, but not always, end up with the WHITE-WHITE code error pattern.

**) Should one of these severe failures ever happen during a firmware update, it is very likely that the device is now bricked, containing a partial or broken code update and thus rendered inoperable and refusing to take further updates. It then should be returned to factory for servicing.
