This set is intended for collectors of Yamaha synthesizers, SY99 enthusiasts, and vintage studio memorabilia collectors. While the demo data itself can be found digitally today, complete, original, unused sets with the original box are rare and highly desirable as collectible items.

Provenance

This set originates from a private Yamaha corporate collection. It previously belonged to a former director of Yamaha Music Benelux, which explains why the disks were preserved unused and never entered circulation.

Not tested, intentionally, in order to preserve the New Old Stock status.
