If you can get any usable results from Finale’s HyperScribe, you are very fortunate indeed!
I second cparmerlee’s view that if you think Dorico’s note entry isn’t the fastest, you will more than get your time back with its speed at producing finished pages, which is second to none.
If you wanted the best of all worlds, you could try entering in another app and exporting as XML, then finishing in Dorico.
Personally, I used to use Finale’s SimpleEntry, and I find Dorico just as fast, with the added bonus that I can add more of the notation in one pass.
