Yamaha Black Boxes

A while ago, I made a Yamaha Black Boxes group on Yahoo. I wasn't sure how many people, if any, would join. I now have 125 or so members, at least 20 of them are real, and have contributed to the group.

First of all, we have the documents which I scanned in. Whole books. Many dozens of hours of work. My friend, and co moderator of the YBB group, Francis, converted most of these to PDFs for me.

You can listen to Session III, an album of GS-1 based music HERE. It is from Yamaha's R & D Studios, made in 1981, featuring Keiko Doi on keyboards.

If you have downloaded any of my manuals, please contribute some money towards keeping the hampster fed, so that he can keep running in his little wheel, so that it can keep making the electricity that is going to the fridge I keep the food and soft drink in, which feeds my brain so I can make the documents that you are reading.

FM Synthesis in Theory and Application [18.5 meg]
This is the book to study if you are serious about FM. A better quality version will be available soon, however, for now, this will do.

Interview from a Radio station with John Chowning. Found via Chowning's page on WikiMedia. Each file is about 5 or 6 meg. The encoding is rather quiet, so, I might have to patch them up, and host them myself.
Part 1       Part 2       Part 3       Part 4       Part 5      

The Whole thing [45 Minutes/28meg]
I loaded the above 5 files into editing software, and made them louder, and compressed the result, now it is much easier on the ear.

Yamaha FB01 Service Manual [4.4meg]
I scanned this a while ago. It was loaned to me from my friend Robin.

Yamaha Tx802 service manual [2.4meg]
After selling the Dx7IIFD back in 1996, I was constantly chasing the FM bug.
In that pursuit I purchased a Dx200. It was an interesting piece of technology, but, sadly, it has way too many problems, and I sold it to get a Tx802. I am glad I made the decision. I had the Tx802 and the Dx200 in the same room for a few days before I shipped off the Dx200, and I A/Bd a bunch of patches. No comparison. The Tx802 is the for real deal, the Dx200, whilst groovy, was not real ultimate FM Synthesis power.

TX802 Power Supply:
Please refer to Exhibit A and Exhibit B.
It is my understanding from the circuits depicted here are quite similar, and that only a few resistors have been changed. It would be possible, in fact, probably relatively easy to change over one power system to another. If anyone notices any different, please email me: Loscha@gmail.com.

Dx7IIFD Service Manual [15meg]
I purchased this when I used to own my Dx7IIFD/E! back in the 90s.
It was expensive, but, I'm glad I got it.
It got me into the habit of buying schematics and service manuals.
A life long obsession!

A good Dictionary of Electronics would go nicely amongst all this, don't you think?

Fanfare for the Common Whippet [376k]
This is something I wrote early Feb 2006 at a BBQ over at my friend Beck's house. She has these two really great Whippets (Quiver and Chase). If I ever got a dog, it'd be a Whippet, cause they look like aliens.
PSS780 Goes for Baroque [332k] - Bent drums, autochord, Baroque Pattern 78
It has a tolerable onboard demo [1.2meg], which, to me, sounds like video game music more than anything else.
