We have recently achieved successful rehearsals of the quintet online using Jamulus to reduce latency (delay times) and allow synchronised playing. It is not as good as being in the same room but definitely worthwhile. Simon created a virtual server just for QW. Robert created a guidance document which allowed each player to get set up and reduce their latency to below 40 ms (sounds like being 7 metres away from each other player). Several friends have now requested copies of this document and are getting set up themselves.
