Congratulations! This is a great unit. The sound quality is top notch and recordings are super clean. Build quality is standard Korg: tough and durable.
I upgraded from a D1600 MkII and haven't regretted it once (especially since I bought the D16XD for the same price I sold the D1600 MkII for!

). I've also installed the optional input expansion board so now I have a full 16-channels of input (and am thinking of buying the analog compressor board for channels 9-16, too--pretty cheap here). Anyway, any document, OS upgrade or other info would be found here:

Happy recording!
