The XG Plug-in System, is a system developed by Yamaha for expanding Yamaha XG tone generators. Yamaha produced a series of "plug-in boards" (expansion boards) for this system. Unlike some other expansion board systems (e.g. the Roland SR-JV80 series), these boards do not just add new sounds, but contain an entire synthesis or effects engine on a board, thus potentially providing more polyphony or additional capabilities to their host device. Korg also produced a similar product in their EXB lineup with the EXB-MOSS board.

Closely related is Yamaha's Modular Synthesis Plug-in System, which uses the same connectors. Exactly how that differs is unclear; the MU100 and MU128 manuals only cover the XG Plug-in System, whereas the MU1000 manual mentions both, without explaining the difference.

Some of the earlier PLG100 boards include unpopulated Waveblaster headers, with unused pads for the necessary supporting circuitry, suggesting that the exact implementation of this system was not a certainty at first.

The PLG100 and PLG150 series board differ in one primary sense: the later 150 series typically include onboard writable memory for user-defined presets, while the earlier 100 series do not. This difference is only relevant for the more studio-oriented host devices, such as the S-series keyboards and MOTIF line, as the MU-series devices offer no facility to write to this memory. There is no issue with PLG150 compatibility for XG devices, they simply cannot utilize this particular aspect of the boards.

The Yamaha MU100 and MU100R are the first modules in the Yamaha MU series to support the system.
