The information on the Korg website appears indicate that files made by the recorder can only be replayed using Korg Audio Gate player. There is no mention anywhere of their system creating the usual DSD file formats .dsf or .dff. There is no DoP support.
AFAIK all dCS components handle DSD either using DoP or a proprietary encrypted interface when the DSD source is SACD.
DoP is now the de facto standard format for the transmission of DSD files ( .dsf or .dff) and was a DCS invention. They also worked closely with Sony from the early days of DSD ( a Sony patent) and the packing of DSD data on SACD. Given the history I don’t think that dCS are likely be confused over the subject:
You will see that native DSD data remains native, DoP only concerns the way that the data are packed for transmission .
Once the DSD via DoP data is unpacked by the dCS component then it is handled natively, unlike the majority of DSD “compatible” DACs which have to convert DSD to PCM in order to process it.
