not necessarily, but it does mean there would be less work ... much less work for the other E-Mu devices listed there ;) it really depends whether or not the devices are USB Audio 1.x compliant. for the most part, the E-Mu devices are. there is a USB Audio 2.x standard now, which mostly just builds on the USB Audio 1.0 standard but does change a few things. it's my understanding that very few devices are using the USB Audio 2.x standard, but that's based on hearsay. to be clear, a device can be USB 2.x compliant and USB Audio 1.x compliant at the same time. there is a small issue with that though: USB Audio 1.x didn't predict how USB 2.x would work, so there is a bit of wiggle room as to what "USB packet" and "USB frame" mean in that case. -- jake...@sdf.lonestar.org SDF Public Access UNIX System - http://sdf.lonestar.org
