Hey Dan -
I'm the CEO of JamKazam. Have you asked for help? If you'll email us at we'll be happy to try to help you. To be clear, are you getting the "latency too high" message while in a session with your Danish friend? Or when you are setting up your gear?
If it's while setting up gear, then the message is saying your audio gear's audio processing latency is too high (not Internet latency), and this can be fixed by changing the ASIO settings on your Presonus audio interface. The default settings on Windows tend to be high latency, and if you're going to play online, you really have to crank these down to minimums.
If you're getting a high latency message while in a session with your Danish friend, that's computed as audio processing latency plus Internet latency, and I'd simply ask how does the latency feel to you guys? We are tough graders on latency. We have many users who can play happily together even when we report that latency is high.
I'd like to clarify a couple of other things. First of all, the audio is routed peer-to-peer between musicians in a session. The audio does not run through JamKazam servers. So the location of our servers is not actually relevant to your latency at all.
Finally, what service is reporting a 17ms ping? Is it speedtest.net or some equivalent. I doubt that is a relevant measurement. The only ping that matters (in the use of our app) is the ping from your computer to your friend's computer. Our app knows what that is, but unfortunately we aren't reporting it through the frontend interface yet.
I'm sorry you've had trouble and frustration in trying to get started. I think JamKazam should work for you, and again, we'd be happy to try to help you. If you'll write us at the email address above, we'll do our best.
Best,
David
