Roland released a line of 12 expansion boards over the course of a few years starting in 2000. Many of their synthesizers have expansion slots and they are an easy way to increase a synthesizer's capabilities with a specific type of sound set.
The Roland SRX expansion boards are compatible with the XV and Fantom series of synthesizers.
The G-70, MC-909, Juno-G, and V-Studio 700 each support 1 expansion board.
The Fantom FA-76, XV-88, XV-3080, RD-700, Juno Stage 2, VR-760, XV-2020, XV-5050 and Sonic Cell each support 2 expansion boards.
The XV-5080, Fantom-S, and Fantom-X each have 4 SRX expansion board slots.
The Fantom XR has 6 SRX expansion slots.
The Integra-7 comes with all twelve expansion boards preloaded in its operating system, but it can't use them all at once, so they have to be installed in "virtual expansion slots".
