Perhaps Alexandre wasn't familiar with the wide
range of Yamaha products.
I'm quite familiar with the language of music as well as some of the
vintage Yamaha gear. I'd assumed that your request wasn't related to a
piece of gear from their Marine Division.
Yep, I am :o) From pianos, organs, keyboards, sinthesizers, to
motorcycles, computers, marine motors and more :o)
But to me, a "keyboard" means only an input
device. If it's a synth, call
it that. And then be specific. A local elementary school issues a
little 30-key synth to each student in their beginning music classes.
(Good, but I still prefer seeing Orff instruments used for that purpose).
But I know Yamaha doesn't make input devices :o)
At any rate, few know of the Yamaha C-1, a few know
about the "hybrid"
PC-music gear, such as the CX5. For example, the DX7 synth is still very
popular among musicians and there's likely a community of folks who know
them inside and out.
I know the C1 too :o) And most of the Yamaha gear, I'm a
piano/keyboard/organ/whatever-has-keys player :oD
Yamaha usually wasn't very open about publishing
datasheets, however. I've
got a couple of Yamaha DSPs in 40 DIP and the best I've been able to find
is a pinout with no legend.
It depends. The Yamaha data sheets are excellent, but the ICs are
**very** old and most of them not used outside USA (beyond the music
keyboard chipsets). So it is not that easy to spot one. In the back times,
if you wrote to Yamaha in Japan asking for a datasheet, they would send you
everything they had about that specific IC and more. Been there, done that.
Many times. Remember I'm an old time MSX hacker :o)
Anyways, if you need something from Yamaha, drop me a mail, maybe I have
that on my lab or my server.
