 Hi Garth,

 I was addressing a single example (release audio) someone else had posted.
 The information was incorrect regarding what ASIO can or cannot do, that's
 all.

 Since I'm on PC I don't really know much about Core Audio, however...
 the lowly SBLive audio card can handle multiple streams of audio playback 
 (up to 64 streams I think) using DirectX. Multiple applications can address
 the card at the same time, no problem. In some ways I think Core Audio
 is quite similar to DirectX. Core Audio drivers will be equivalent to
 the recent Microsoft low latency WDM driver standard. 12Tone's Sonar has
 adopted this standard. Like Core Audio, DirectX is part of the OS, not an
 add-on like ASIO.

 This is not an OS war, just clearing things up.

 Actually have to hand it to Steinberg... when no one else had low latency
 drivers they came up with ASIO. We tend to take it for granted, but look
how
 much we owe to that standard... VSTinstruments, real time monitoring
 w/effects, efficient drivers...etc..etc.
