Is it thus possible that - because you had to - you did effectively train yourself to ‘hear’ what you’d written?
Or was it ms paper, pencil - and piano (etc)?
If not, how would one set about ‘making’ the sound of the notes inside one’s head that way?
I can see how a chord (or note, of course, for that matter) just entered ought to be recallable.
Although even then - and I have a good ear - I can’t really hear it. Failing?
So if I decide to add/insert a small section after a chord which I want to step-play, and absolutely couldn’t hear, I’d probably copy it into a bar by itself 10 or so bars further on and have Dorico play it as normal - as a kind of reference; in the hopes that it would stay in my head while I wrote after the ‘original’ in-place chord.
That’d be a long way round, though, wouldn’t it?
