[Coco] CoCo MIDI company after Speech Systems?

[alsplace at pobox.com]

Does anyone remember the name of the company that came after Speech 
Systems, which sold the CoCo MIDI interface and Lyra (Lester Hands)?

If so, does anyone remember the name of the guy who ran it?  He had a 
license plate, pictured in Rainbow one time, that read HD6809B or 
something like that.

My memory is very bad.  I used to speak to him from time to time, and 
he even sold my Kawai K1 keyboard librarian program!
