"This unit was used by Philip Glass, Michael Riesman, and the Philip Glass Ensemble for performances and recordings from the early 80's until it was retired from service on the road later in the 80's. It was then retrofitted with a MIDI interface and used only in the studio. It can be heard on a number of albums including 'La Belle et la BĂȘte' from 1995. It has been used seldom, if at all, since that album was made, and has been in storage since 2009.

The built-in keyboard is barely functional - only about half of the keys (in the middle of the keyboard) make sound Probably all that's needed to fix this is a cleaning, but this isn't something we have wanted to bother with, because the unit is 100% functional via MIDI and that's how it was used in its last years in the studio. It could be that the keyboard has been in this condition since the 90's. The keyboard action feels fine, so it's not a problem with keys or the the bushings. The fact that the middle of the keyboard plays supports the notion that the problem is just dirt. because it's the least-used keys that don't work, because their contacts haven't been burnished by use.

I think the MIDI kit was made by JL Cooper, but am not sure. Instructions for use are on a piece of tape, shown in the pictures. Whoever made it, it works."
