I'm a retired Computer Science professor whose hobby for many years has been arranging music for recorder consorts, originally to support weekly meetings of recorder-playing friends. During the pandemic, we have continued to meet on-line using Jamulus software. I use MusiXTeX to typeset music scores and am actually the maintainer of this free software package, as well as many other TeX packages. You may contact me at rdtennent(at)gmail(dot)com. I live in Kingston, Ontario, Canada.
