Sure.. so the beginning of the story up to the Avid acquisition is publicly documented as Sibelius' history and so on. The development and release of Dorico has also been written about in depth on Daniel Spreadbury's blog, "Making Notes". There used to be some on his Twitter as well. The middle bit is alluded to here, for example: https://newmusicusa.org/nmbx/avid-keeps-sibelius/ https://newmusicusa.org/nmbx/avid-keeps-sibelius/ And there were long, if somewhat speculative threads on Gearspace (fka Gearslutz) and various composer forums at the time. A few bits I got word of mouth from friends who worked at Yamaha at the time.
