| Just wondering if the audio folks here would know what's going on with ASIO and the ability of multiple programs to connect at once through an ASIO interface. Mostly I use an M-Audio PCI sound card. Under Win XP, as far as I could tell, it was allowing multiple programs to connect via ASIO simultaneously. For instance, if I connected a sampler through asio, then later ran csound and checked the list of devices one of them would be ASIO and I could connect through that. For a while I used a M-Audio Transit USB sound interface. That behaved differently-- if one program grabbed ASIO, then other programs would not show an ASIO option in their list of interfaces. Because I wanted *csound* to have ASIO above all, I needed to run it first by habit. Some programs such as Finale seemed to grab ASIO as soon as csound would exit, and then I couldn't run csound through ASIO again without killing Finale first. I'm back to the PCI card, but now under Win 7. It's behaving a lot more like the situation I had with the USB box -- programs "grab" ASIO and no other programs can see it. This is pretty annoying -- it was convenient not to have to think about what programs to start first and not have to restart everything if one thing exits. I'm curious if the ASIO spec says that multiple programs should be able to connect simultaneously. Dennis |
