Yes - well I have gigabit Lan connection between two computers. I'm not using a switch at the moment - I've bridged two connections on one computer, allowing connection to a router. But the computers are directly linked by ethernet cable. I've also tried it as a simple crossover cable arrangement.
For a time, I thought I had cracked the situation. One of my cards wasn't actually running at 1000 mbps. But once I forced it to, I got a very usable result.
Today though, it was back to an unusable latency. That is I'm talking about playing a note, and the sound coming late. It's not as bad as it was when I first opened this thread (because I was obviously at 100 mbps then) - but it isn't good enough. Not a patch on the results I'm used to getting from simple Midi Over Lan - but using an audio interface in each slave computer.
This was my big issue with FX Teleport. I spent all the money on a gigabit switch and gigabit NICs and MOBOs with built in gigabit LAN but found the thing unreliable.
I'm seeing the same unreliability here. And what are we supposed to do, bounce around for days on a forum, debating whether it is this setting or that hardware that is the problem? Spend money on something else - does it fix it - maybe / maybe not.
I simply can't see how LAN technology (which requires every bit of information to be put into a packet, received, acknowledged etc.) no matter how theoretically fast it is, can be a substitute for sending a digital signal or analog for that matter over an audio or digital cable. The only conversion there is Digital to Analog - and if your sound card is good, you get very little latency.
