A new song snapped to whole bars, too coarse to lay out a beat. And a new or duplicated sound, instrument, pattern or song went to the master alone, so every one had to be linked into the buses by hand again. - A song without a grid of its own snaps to 1/16. The songs in the user's project have Bar written in and keep it. - A new or duplicated sound, instrument, pattern or song gets the links of the one whose targets most others of its type share, at their volume. On a tie the latest of them decides, so a single song decides for the next one. - Where nothing of its type is linked yet, it goes as most of all that plays, and where nothing is, to the master. A new bus still goes to the master alone. - Assets made at once are matched against what stood before, not against each other. A project from before the routing still opens with everything on the master. - The song tab has a gridAt hook. e2e 65 checks the new grid and sets Bar, which its checks go by. Tests: - Unit master-routing (1 new) and song (1 rewritten): 26 green. Counter checks (rule off, grid back to Bar) red. - e2e 65 (melektaus-atx): ALL PASSED, 58 checks (1 new). - Gate (melektaus-atx): CHECK EXIT 0, 273 files, 4226 tests.
