Dan,

So you're saying the audio recorder and its track count aren't on a dedicated Korg PCI card in the Oasys and not 16 BIT? It's my understanding the audio card for the recorder is 16 BIT and all audio recordings are 16 BIT at 48K but the D/A outputs of the Oasys are 24 bit. Even Korg's literature states the audio recorder is 16 BIT at 48K (see link below). When did those specs change to 24 BIT at a higher sample rate?

If the audio and track count aren't fixed by the PCI card why would Korg claim the Oasys to be 24 BIT yet make the audio recorder 16 BIT and only 16 tracks? That makes absolutely no sense. Korg needs to update their information on the Oasys if the audio recorder is now true 24 BIT which I doubt that it is.
