I have gotten pretty decent at playing the fipple flute after about 200 hours of playing soulframe more or less. When I first started playing I was absolutely terrible at it. After getting a lot of experience with it I've realized a few things that have made it easier to play and have a few suggestions that could improve it and make it easier for players to get the hang of it.
First off I couldn't really play the fipple flute at all till it was bound to keybindings that I could intuitively use which for me was 1-5 on the 10 key numpad. Something like this should probably be set as default, with maybe a couple easy to use layouts.
Second the orientation is very difficult to deal with for me as I am right eye dominant. I have found that if I close my left eye it is easier to see the line and tell exactly when the notes are touching the line which is a requirement for perfect notes, so at the bare minimum we should get the option to flip the orientation right or left but I see someone has also asked for top down orientation in another thread here.
Third the single line is just not enough. 2 lines would be much better allowing you to center the note for better timing. Adding a transparent coloration between the lines that maybe glows when the note is perfectly centered would really help with timing as well just to make it absolutely clear when exactly to play the note.
Fourth a metronome that plays to the timing of the song would be extra helpful for a lot of people who are just bad with rhythm. Would have to be an audio tick or something of that nature that could be enabled/disabled in accessibility so once you got good at the timings you could just turn it off.
I know people wanna freestyle on this thing and play songs. So it would be great to be able to make and store songs you can then play later and having an autoplay function like warframe's shawzin would also be pretty cool.
What do you think envoys?
