The SRX are a series of expansion boards produced by Roland Corporation. First introduced in 2000, they are small boards of electronic circuitry with 64MB ROMs containing patches (timbres) and rhythm sets (drum kits). They are used to expand certain models of Roland synthesizers, music workstations, keyboards, and sound modules.
Predecessor formats include the 15 SN-U110 PCM cards (U-110, U-20, U-220, D-70, CM-64 and CM-32P), 8 SL-JD80 PCM card/preset RAM card (JD-only) sets and 8 SO-PCM1 1-2 MB cards (both JD-800, JD-990, JV-80, JV-880, JV-90, JV-1000 and JV-1080), 22 SR-JV80 expansion boards (JD-990, JV-880, JV-1010, JV-1080, JV-2080, XV-3080, XV-5080, JV-80, JV-90, JV-1000, XP-30, XP-50, XP-60, XP-80, Fantom FA76, XV-88) and others.
The Roland INTEGRA-7 Racksynthesizer included 12 SRX-Boards from SRX-01 to SRX-12.
According to Roland,[1] the following products accept SRX expansion boards. The number in parentheses indicates the number of SRX boards each unit can accept.
Some later SRX cards, for example the SRX96 and 97 do not work in the XV3080 host synthesizer module nor in the XV-88 keyboard synthesizer.
