Yes I had a little dribble over that video yesterday, though Emerson's, named Roger the Synth, was slightly different as it had preset modules for setting presets.
Yes, I had understood these commercial products were a follow on from the original "Roger" project.
Prices of these models are considerable less that the $92K mentioned by Jeff but still way out of reach to most people.
There will be 55 units of the System 55, priced at $35,000 per instrument;
35 of units of the System 35, priced at $22,000 per instrument;
150 units of the Model 15, priced at $10,000 per instrument. (a misprint in the article, it should be 15 units!)
