the GS logo. The XG-compatible Yamaha S-YXG50 SoftSynthesizer, which is discontinued, is an entirely software-based MIDI synth. It used a 2 MB or 4 MB wavetable sound set, and was common among non-professional users who needed a cheap, high-quality MIDI synthesizer for purposes such as playing games that rely on MIDI to produce music and sound effects. Korg compatibility Korg, due to its close relationship with Yamaha, released three instruments with XG compatibility: the NS5R, which offered XG compatibility through an add-in daughterboard; the NX5R, electronically similar to the NS5R, except that the daughterboard is part of the instrument; the N-series of keyboards and modules, which also offered support for Roland's GS and GM2 standards as well. Korg was the only manufacturer outside of Yamaha to produce XG-certified instruments.
