This one spotted by prophei. He downloaded the sysex for the three individual OSes for the DSI Poly Evolver Keyboard off of the DSI website. When he looked at the manufacture in the Mac OS X SysEx Librarian this is what he saw. Anyone confirm?

Update via wavedeforum via the comments: "The manufacturer ID is not IP that would get sold with Sequential Circuits. It is an ID issued by the MIDI Manufacturers Association. Usually a number is retired or recycled when a company ceases doing business.
Because of Dave Smith's role in getting MIDI going, he gets to keep his ID, which is 1.
It's the programs that interpret Sysex that lookup the ID and display an appropriate string that are at fault for still displaying Sequential Circuits. I would think that they should be revised to display DSI/Sequential or something similar."
also sent my way privately via Stephen via Synthwood. Pretty cool when you think of it. Dave Smith was THE man behind MIDI. SCI was first with the Prophet-600 followed by Roland with the JX-3P. I'm guessing Roland has ID #2, but I have yet to confirm this. Be sure to see the comments of this post for more.
Update via Dave Cornutt in the comments:
"Roland is not ID #2 because the IDs are divided into three groups, American, European, and Japanese. The American group starts with 1; the European group starts with 20 hex, and the Japanese group starts with 40 hex. Roland is assigned ID 41H; for reasons unknown to me Kawai was given 40H. Here's the whole original list, from "The Complete SCI MIDI", January 1984 edition (all numbers in hex):
