Ninjam is very cool and mature software with a nice community. However, not everyone can get used to the idea of playing one bar behind everybody else. While it can provide almost no-latency experience, some people just can't wrap their head around it. And, of course, it prevents rhythmic development and severely limits freedom of improvisation. For static beats and repetitive harmony it works great, though. If you'd like to try jamming completely simultaneously, try Jamulus (federated client-server architecture) or Sonobus (p2p). Both are free software and work very well, at least as well as physics allow. In-city jams are hindrance-free, close cities and even close countries are usually painless, as long as everyone's on Ethernet, of course. https://jamulus.io/ https://jamulus.io/ https://www.sonobus.net/ https://www.sonobus.net/
