Is it just me or does the ShowCo ShowConsole surface look a lot like the CS1D?
The format for almost all large consoles followed the analog equivalent for a while regardless of what was "under the hood".
The CS1D was a departure from the PM 2000 (and Midas desks of the era) right hand sub master layout to the more ergonomic, generally preferred center master section.
Yamaha was quite interested in the USA market, and followed many leads, bringing to large scale production what was only a cottage industry here.
