When you have a very complex song, it's very cumbersome to have to shift+click+drag each individual pattern/beat/bassline and piano roll in order to extend the song and repeat certain sections. It would be very nice if a feature were added that would allow me to shift-drag all patterns that are selected with the selection tool on the song screen (Which is pretty useless to me, as all it does currently is make deleting large sections easier?), or allow me to Copy+Paste a selection. It really messes up my work-flow having to shift-drag each individual section of each individual track.
Absolutely this! Several projects I am working on have 5-6 tracks alternating melodies and sound to create the basic theme of the song. It is incredibly time-consuming to have to ctrl-drag each individual pattern to its new place if a section repeats itself. I would love a feature that allows me to copy and paste multiple tracks. It would shave tons of time in the composition process for me.
Totally agree, this feature would be very useful.
