Racks
Each project holds up to 8 MIDI racks. A rack is a chain of MIDI devices (filters, arps, scalers, etc.).
Rack list
Main Menu → Racks shows all racks in the active project. The header title RACKS sits in an open tab, with a small shadow on each side, and a line under the header separates it from the list. Each named rack has a two-digit number, 01–08, dim beside the name. Turn the encoder Select a rack to open its device grid.

| Control | Action |
|---|---|
| Turn the encoder Encoder | Select rack |
| Select | Open rack device grid |
| Long-press Select | Side menu: Rename, Duplicate, Clear, Snapshots |
A rack name is at most 10 letters. Duplicate adds COPY, and shortens the original name when both will not fit, so the copy stays a different name.
Device grid
Each cell is one device in the chain. MIDI flows through devices in chain order.

| Control | Action |
|---|---|
| Turn the encoder Encoder | Select device |
| Select | Open device parameters |
| Long-press Select | Options: Duplicate Device, Move Device (when it can slide), Remove Device |
Add a device
Open the device picker from an empty slot or replace menu.

Types that are dimmed cannot be added right now — the rack may be full, or that device type is already at its maximum. Selecting a dimmed type shows a short explanation.
How many devices fit in one rack, and how many of each type, is summarized in Rack chains.
