Yamaha S-YXG50 Portable VSTi v1.0.0 (a software MIDI synth)

A software MIDI synthesizer for Windows, which functions as a VSTi plugin. Supports both the Yamaha XG and the Roland GS extensions, which is a unique feature of the S-YXG50. It is based on the trial version from the Yamaha SOL2 package. The full version of this VSTi had never been released, because Yamaha had decided to discontinue support of all its software synthesizers in 2003. Fortunately, the trial version have a full version of the S-YXG50 engine, so it is possible to remove the trial restrictions to get a full version. In addition to the removed trial restrictions this patch adds the portability (installation and registry keys are not needed), also it uses embedded into the DLL resources the 4MB official wavetable files, which is the best version of wavetable files for the S-YXG50.

Yamaha S-YXG50 was released in 1997. First versions were shipped with the simplified 2MB version of the wavetable, and the full 4MB version was published only in 2001. It seems that the cause of this is low amount of RAM in the computers of 90s. Both versions of the wavetable files were created in 1996 (4MB in February, simplified 2MB in July). Possibly, the full 4MB version is a dump of the WAVE ROM of the Yamaha MU80 / MU50 / QS300 / DB50XG / DB60XG / SW60XG / MU10, because the Yamaha S-YXG50 soft synthesizer is very similar to this series of hardware of 1994-1996.
