Round three had left a handful of questions open, each with a default the designer recommended. The owner, reviewing the deploy that carried the legal redline, took the defaults as a set.
What was decided
Advanced mode costs nothing. Every effect in the rack is free, and each new engine arrives with two free presets and two reserved for Pro members, so the paid tier is sounds, never capability. The mode is a setting on the song, Basic by default. A song made in Advanced plays the same for a Basic maker, who simply does not see the panels. Velocity stays, and so does the thirty-two-step grid; if anything must be cut for room, the extra cells go first. The shared delay bus, which would have let one delay serve every instrument, is dropped in favour of the per-instrument rack.
Why sliced, not built whole
The manager’s stance is that Advanced mode goes in pieces, because the initial download is close to its budget and there is little room left in it. So the order is the effects rack first, then the engines, then the advanced mixer, each a slice with its own review.
The same day a new manager session took over the project, and a small slice was dispatched to keep the public licensing page tied to the legal text it is drawn from, so the two cannot drift apart again.
