In the last couple of weeks Duolingo on my iPad abruptly closes while I am doing my lessons. No pattern with respect to where or when, but it does it every time I use it. I am a many years long user currently on a 1354 day streak. I have sent in two reports, with no reply. Any others experiencing this?
I am a tuba player. I occasionally get a piece for a quartet I play in that has runs of notes outside my range either high or low. I would like to transpose them down or up an octave. I can do it manually by writing the notes in, but that gets messy and distracting. I can scan and print it, white out the section and draw in the lines on the staff and insert the notes. I tried an app that allows me to scan the piece and then annotate it but it was excessively complex. I would appreciate suggestions on what an effective and manageable method of creating an annotated score. And yes, I know that if I were experienced and talented enough I could just play what I see down or up an octave, but I’m not that good. 😌
