I succeeded in hooking up a digital keyboard (Y.. PSR-E423) via USB to a PC ... and the keyboard 'typed'
notes right into a blank MuseScore score-document - without further adjustment! Yea! ... most importantly, chords, too, which are time-consuming to enter via a PC keyboard.
The only issue, I can see, is that the process doesn't, directly, know about note-duration (e.g. quarter-note vs. eighth-note etc); you have to choose the note-duration with your mouse.
The only major downside is that I'll have to learn some keyboard notes - to 'type' the input :contrat: That shouldn't kill us, right?
It's a heck of a lot faster than trying to 'scan' and re-edit.
... and MuseScore can/will 'play' your score back (for confirmation), using synthesized tones for whatever instrument, you designated, upon creating the blank score document.
Now, we can re-finger and re-position to our hearts content; then, re-Print for our loose-leaf repertoire book.
