Optigan, the organ optical disc of the seventies.

Optigan rightfully belongs to this category, but with a singular peculiarity. The optical organ, in fact, made by Mattel in the early seventies rather than play simulated instruments, drew to a disk the size of an LP record with optically encoded in Real Instrument loops and accompaniments which integrated the classic functionality of the keyboard. Pressocch? all the knowledge about this curious instrument? was collected on this site with patience and trying not only to document the existing, but also to bring together the different users of the instrument remained the same. Of the materials available it is worth remembering a list of albums released, their possible duplication techniques, forums, assistance on the machines, the pdf of the manual, and an old simulator for pc free download.
