Indeed. The latest Oppo box has the same problem. But perhaps people only listen to 4 minute singles these days.

I quite understand that the demands made by one file per track recordings on writing to storage in real time are currently too great to handle, whereas boxes like the Alesis HD24 and RME UFX will store between 24 and 60 hi res tracks using multitrack files and proprietary storage formats; but on the other hand, why not either write soft/firm-ware that will link these together, or separate them into single files, for playback?
