Aroelina: Corrected PLG board information. “User Voices” also exist on the PLG100 card. (This is an odd way to put it, but) Yamaha's preset user voice data is used when power is turned on. User Voices can be adjusted and saved using a dedicated app; they cannot be saved to the main unit or board. (They are initialized when power is turned off.) These User Voices are unrelated to the PLG150's non-volatile memory.

Korg also produced a similar product in their EXB lineup with the [[EXB-MOSS]] board.

	These XG plug-in boards (PLG100-series) can be thought of as the first generation of Yamaha's '''Modular Synthesis Plug-in System''', a branding convention which was established later, with the PLG150-series boards. The two generations are mostly cross-compatible, and the differences between them are not precisely defined. The MU100 and MU128 manuals only refer to the XG Plug-in System, whereas the MU1000 manual mentions both.

	The most obvious, practical difference, is that the onboard non-volatile memory which was added to the specification for the PLG150-series boards, was not made directly accessible via the interface of XG devices. This addition was only available via more studio-oriented host devices, such as the S-series keyboards and MOTIF line, allowing for on-device storage of user patches and settings. There is no fundamental incompatibility with PLG150-series for XG devices other than this limitation, though early firmware revisions of the MU100 apparently have issues with certain boards, requiring the updated firmware 1.11 for full compatibility (originally available from Yamaha on a new ROM chip, part #XU507200).

	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 PLG100-SG and PLG100-VL boards include unpopulated [[Waveblaster]] headers, with unused pads for the necessary supporting circuitry— this could suggest that the exact implementation of this system was not a certainty at first. Since these two boards were made available in a software form for Windows, it may have been determined that the inclusion of the waveblaster interface was not needed.
