For me it was sort of a first love elation, but I feel as if I spoke too soon in this thread. It does work as advertised so can’t complain about the product. But alas, once past the first experiments with a couple of instruments - I’ve found that the load on my machine is (perhaps obviously) much higher that running Dorico alone, which means the sound devolves into crackles and pauses that much faster.
I might find use for it? But because offline audio exports from Dorico are always artifact free, I find it much more useful to build a high level sketch first, then work on certain parts or section at a time, export as audio and import a “video” of my current progress into Dorico as I work on remaining sections. I have hopes that version 4 will have made the on/off switches for instruments in the play tab a little more finished and consistent in their display.
