    Default Any one playing on Jamulus?

    I have been playing on jamulus since March but still don't see any bluegrass playing.

    Anyone playing on jamulus or does anyone want to try?

    I’ve tried both jamulus and jamkazam, hoping they would allow for some real-time remote practicing or playing with others. Both claim to deal with latency issues (the delay resulting from signals traveling distances) that make playing over platforms like zoom impossible. I found that neither work well. Interested in hearing from anyone who has had success and their tips for making it work.

    All online jam services have latency issues. It is simply physics and can not be removed with software or a faster server. The further each party is away from each other and the more different kinds of networks are being used the worse the problem is.

    Actually, there are a number of key breakthroughs in latency issues, and folks using JackTrip technology have been able to get audio latency down to virtually imperceptible levels — under one millisecond, well under the threshold of what is perceptible — even with large choruses and orchestral ensembles.

    I wrote about a plug-and-play rollout of the JackTrip-based Virtual Studio for the Bay Area's Ragazzi Boys Chorus that is really promising. You can read that story here.

    If you don't have the option of setting up your own JackTrip Virtual Studio server, you can rent time on a managed regional server for a very modest fee (estimated at $1/10 musicians/hour. FAQ: https://jacktrip.zendesk.com/hc/en-u...sked-Questions

    The Virtual Studio folks mentioned in the article are about to roll out the plug-and-play interface to the general public. More info here. The great with all the bells and whistles looks to be about $150–200, but it's possible for savvy DIY electronics mavens to do it for about half that using the free JackTrip software and a cheep Raspberry-Pi microcomputer.

    The engineers I know who are exploring this consider it a game changer.

    From the Virtual Studio page:

    "It minimizes latency by using software and hardware that is optimized for the transmission of audio over computer networks. Most people who have tried it so far are able to achieve one-way latency of under 40 milliseconds, using typical home Internet connections."

    One-way delay of 40, return delay totals 80 milliseconds. This is barely usable. The Jamkazam approach is a common metronome. Otherwise you adjust your playing to a delayed sound, and the others then adjust to your slowing, and so on.

    I have personal experience of this in physical space. When a chorus and orchestra were spread over a hundred feet it was hard to keep the tempo up, even with a conductor, because of the desire to synchronize the sound. In another venue, we were crowded together and the tempo was brisk and did not drag. Even fifty feet separation means 100 milliseconds return delay

    BTW, the main delay problem is the computation that occurs to packetize and re-assemble your data. It will be present even in the same neighborhood.

    More from Virtual Studio:

    "Virtual Studio sends your audio over the Internet, which is limited by the speed of light. Light takes about 67 milliseconds to travel half way around the world, but the Internet is less efficient and in reality it can easily take 150-200 milliseconds.

    Even 67 milliseconds is a lot of delay. Research suggests it's very difficult to perform music with a delay greater than 25 milliseconds. However, that doesn't mean it can't be done. Your success will likely depend on the tempo and type of music you are performing. Many musicians are using JackTrip today to perform music over very large distances. It just requires a greater degree of adaptation."

    It's been work for me..

    Just go and try it..Jamulus.
    I was just on with about 20 players.
    Yes it's not all joy..but it does let you play with others
