That seems a very likely candidate, for a number of reasons, including its dedicated 'noise' output. Perhaps even a stereo (mirrored stick-figure image) 'granular'* (and possibly vocoding) hybrid, that can load/record samples.
* = micro-sampling 'grains', which are typically 5 to 200 milliseconds (ms) long...
[Video screen-grab "clues", from previous post]
...'duration' and 'amplitude' (modulation)
... 'grains' or perhaps sequencer?
The Telharmonic had three 'voices' of twenty-four sine waves each, tuned to harmonic ratios of the fundamental. Note the cut-off text in lower left hand corner... The videos for it frequently use the term "elements" as a descriptor, and there are references to harmonics in the other images.
