Sort & Repack
Sort & Repack reorders fixtures and automatically recalculates their DMX start addresses so the universe stays clean and sequential.
What It Does
When you reorder fixtures using Sort & Repack, the app recalculates each fixture's start address based on its new position in the list. Fixtures are packed sequentially with no gaps between them.
When to Use It
- You added a new fixture in the middle of your rig and want to insert it between existing fixtures without manually shifting all addresses.
- You removed a fixture and want to close the address gap it left.
- You're reorganizing your fixture list to match the physical rig layout.
- Address ranges have become fragmented after multiple edits.
How to Use It

Open the fixtures list
Navigate to the Fixtures tab.

Review and confirm
Review the new addresses before confirming. Update your physical fixtures (DIP switches or fixture menus) to match the new addresses.
Example
You have three fixtures and add a fourth in position 2:

Address Gaps
Sort & Repack eliminates gaps between fixture address ranges. If you intentionally want to leave unused channels between fixtures (for example, to reserve addresses for a fixture you plan to add), do not use Sort & Repack — set start addresses manually instead.
