Voice settings for a digital polyphonic keyboard synthesizer. RMI was a subsidiary of the Allen Organ Co. and the RMI Keyboard Computer was a version of the Allen Computer Organ, which used similar punch cards. Pre-punched cards were available, but users could also punch blank cards to create their own voices (or possibly punch random holes just to see what happened.)
