This paper follows up on 2012 and 2013 AES presentations on recreating the first successful electronic organ, the 1927 Robb Wave Organ.
Most historical literature lists the Chamberlin/Mellotron (c1960s) as the first usable sample-based electronic instruments. This paper will situate the earlier 1927 Robb Wave Organ as part of the evolution of sample-based instruments. It will also demonstrate the sampling method used of carving Pulse Code Modulation (PAM)-equivalent waveforms into spinning tone-discs.
The authors have completed a physical recreation of the instrument and will demonstrate the various sampled sounds at the conference.
It will also be displayed and playable by interested AES attendees.
