I use the You Can Teach Yourself Fiddle on my Pro from the Kindle App. I won’t be doing mark ups like I do for my lessons, so that is not an issue. I just use my Pro with the Kindle app when I use that book. Very handy. If I go outside or a trip, I can bring my paper copy with me. All is good in iPad Pro Land. 😁
They call me, “Mellow Cello”
I just take photos with my phone to get the sheet music into the fscore app - it looks ok..... My iPad seems to take all the kindle stuff, but I'd much rather hold a book to read (old style) while sipping a nice cup of hot tea! - and I have to admit, I'd rather read from the sheet music on my music stand.
I tried to go paperless at home, and only really got as far as the sheet music. Bought so much in the beginning, and have so many tunes that I can't play yet, because of either time or they are just too hard, but one day I hope!
