Hi - In 1977 and 78 I was Stevie Wonders electronics engineer. I had the privilege of working with the Yamaha GX-1. Stevie had seven  CS-80's. When I left Stevie and went to work at David Abel's piano store in Beverly Hills, I was tasked to make mods to CS-80's. Abel's was a premier dealer for Yamaha. Many musicians and composers came to Abel's to buy their instruments. I designed an interface for a Imsai Z80 computer as a CS-80 programmable controller. Clark Spangler was a salesman  and studio musician. The CS-80 was his go to machine for many movie/television/commercial soundtracks. Brian Banks used the CS-80 on many movie scores. Seeing your video brought back many memories. The CS-80 did have an issue with staying in tune, so I designed a fan box that would blow air through the bottom vents to keep all of the voice cards at a stable temperature particularly during live performances in clubs . Richard Lubbing was our keyboard tech and would rework the keyboard of the CS-80 for better touch and action.

"Attack ships on fire off the sholder of Orion."
That's how to describe the magic of CS-80.

I am not a musician and don't own a synthesizer, I just like watching craftsmen at work.  Cool stuff!

Cody's excitement: -14/100

This video was more entertaining than 90% of modern day T.V.   Such a pleasure to see your enthusiasm and skill at work.  From a pinball enthusiast who collects and restores machines (with help of course) I'm very happy to see you looking after these easily forgotten treasures.

It is a blessing and a curse to own a beast like this knowing the parts for it are so rare.

I didn't realize Billy Bob Thornton was an 80's synth enthusiast.

I thought I was a keyHoarder... My wife needs to watch this if only to convince her that my "problem" is benign.

This is like watching actual tv. It's incredible

This was awesome in every way.

Hi, Cs80 owner here
thanks for saving one of these beasts
they're definitely fantastic and unique instruments
they need to survive and keep being played!!

This planet needs more people like this!

This is the synthesizer reality tv show I never knew I wanted! Gerald is the man!!!

The fact you so casually called up one of the Thriller keyboardists is amazing

Whoever directed this (not sure if it's just you or your team of 3), did such a great job, as it draws you into the story.

32:10 The lost sessions of the Pink Floyd Wish You Were Here album! Amazing sounds!

This is golden content. All the rareness in one place, from rare synths to the most important people linked to them, all in one episode!

What an education in being methodical when doing repairs, of anything!

I hear you guys are in talks with Netflix for a show called "Synth King"?

43 minutes never passed so fast, in awe of your passion.
