One
additional remark:
Since the current "Area-Selection" was postponed - for
whatever reason - my suggestion for improving Reaper
would be:
Why not take small steps?
By this I mean: To make these essential modularity + repetitive
structures possible, it is actually sufficient to create a
"box"
only for audio items! So only for one track, and the
audio items contained on this track (for all lanes!) you can
"draw" a box. And this box can then be moved, copied or even
pool-copied as a whole.
This initially simple feature of the
"Audio-item-Box" would
enable Reaper to arrange everything modular and referenced.
