A very important OS update (version 1.12) for the Nord C2D has been released recently, which fixes a critical bug causing System settings, Live buffer and Pipe Organ samples to become corrupt. The update is strongly recommended for all Nord C2D owners! The issues mentioned could occur during long periods of use (having the C2D turned on for more than a few hours - no exact numbers available here), during which time the data of an important memory circuit would be accidentally overwritten. For further details concerning this, please contact support@clavia.se.
The OS update is available for download from the website: http://www.nordkeyboards.com/downloads/products/nord-c2d-organ
