Without Squids, Life Would B♭

This puzzle uses the Octopus Rules from The Pedalling Pianist together with Region Sum Lines. Thanks to all the testers!
- Irregular Sudoku rules apply.
- Asymmetric Region Sum Octopus
- Draw 4 lines that must not cross or overlap anywhere except R4C4, where they all intersect.
- All lines pass through R4C4 in a straight line. Each line contains exactly 2 cells on the edge of the grid where it starts and ends.
- The 4 lines are independent region sum lines. Region borders divide them into segments with equal sums.
- Cells with ♯ symbols count as one more than their digit for region sum lines. Cells with ♯♯ count as two more and cells with ♭ count as one less.
Example Puzzle
These images show a 5x5 example puzzle (left) and the corresponding solution (right). The four segments of the red line are highlighted in four different colors. You can play the example here.
Solution code: the bottom row, left to right (7 digits)

My first attempt fell flat, but I noticed my silly error and was sharp enough to solve second time round!
Nice puzzle, thanks for setting.

Do we assume the digit set is 1-7, since it's a 7x7 puzzle?
