That all seems like ancient history. Better than how composers worked in the Baroque through Romantic Periods, but not a lot faster.
Now, I take almost for granted the powerful notation software that lets me write, make corrections, change the layouts, make transpositions, use interesting fonts, and test instrumental sounds almost instantly! I can even print out as many professional-looking copies as I need on the spot and make mp3 demonstration files. All from my computer desktop. Amazing!
