Just remove the entire page system.... its either too long or too short. just make a scrollable note grid instead with a - and a + on different sides to increase/decrease the song length. and then this could need more layers/tones. examples; Guitar Piano Drums and ofc the specials. also, alot of people want to be able to change the tempo (they also want repeat) between note x and note y and repeat that z amount of times. This sums up most of the changes the fans want. [+] and copy/paste this to keep it alive long enough until the dev implements this!
