I have learned to live with the bugs in HA. No problem. HA compared to Sibelius is not a problem. If you have to make an oil painting you start with a pencil and make a sketch. When you are satisfied with that you move over to the oil colors. For me HA is the pencil and when the sketch is OK I continue with Sibelius to make it into something real. In the first drafts you often want to insert or delete notes, replace a quarter with two eights or one eight or change the duration of a note in a melody. HA makes inserts and deletes a trivial thing compared to how Sibelius makes it complicated. Or there are perhaps features in Sibelius that I have not noticed.
For me Sibelius was a substantial investment but I don't regret it.
It is easy to write scripts for HA. I have written perhaps ten scripts that makes sketching fast and easy.
So my tools are HA->Sibelius->Reaper. I have looked a Logic Express as a replacement for Reaper but don't really know yet. I recently bought a midi keyboard, KeyStudio 49. I have tested it with all three programs. My preliminary feeling is that Sibelius is the best of the three for my kind of live input.
