[net.music.synth] keyboards & MIDI

kelpie@fluke.UUCP (Tony Garland) (09/16/85)

Being real new to the world of synthesizers, I am still naive enough to be
thinking about designing and building some sort of basic synth.  However, I am
in need of the following information:

    o  Where can one obtain  a "raw" keyboard? To be specific, is it possible 
       to purchase a keyboard mechanism mechanically complete which I
       could design around to provide velocity sensing with say 3 to 5 octaves?

    o  Am I crazy approaching it this way?  Instead, should I be looking for
       a keyboard which merely provides MIDI out for use in controlling other
       devices on the MIDI bus?  Are there even any keyboards out there which
       are MIDI compatible, but just produce output onto the bus without
       generating any notes of their own locally?

    o  Where can one obtain the detailed engineering spec on MIDI?  I presume
       there must be some sort of hardware standard as well as some software
       protocols?

    o  Last, but not least, am I crazy?  Are synths so far gone (advanced) at
       this stage to preclude realistic tinkering by an individual?  Am I
       likely to sweat it out only to produce a relative toy (compared to the
       what full-time engineers and LSI can do in the commercial products)?
       I am interested it *both* learning *and* producing something that sounds
       good enough that I will feel good about it.  Can someone with good
       hardware and software background still add value by building rather than
       buying?

Thanks in advance,

tony,
first of all for raw keyboards check out paia in oklahoma city....they're a
mail order electronics/music warehouse and they do sell some keyboards...
on the other hand a midi controller might be the way to go.
for midi information check out the following sources:
the note in this newgroup titled 'network midi primr'
the book published by keyboard mag. 'synthesizers and computers' has a
full copy of the rev 1.0 midi spec in its appendices.
I think you can certainly tinker away, although if you want to tinker with
equipment that is currently popular (not neccessarilybetter) you'll
probably need a good understanding of analog electronics, digital electronics,
and computer design.
hope this will be some help.

As refered to in article 187 good raw keyboards are available from
PAIA Electronics, Inc.
1020 Wilshire Blvd.
Oklahoma City, OK  73116
(800) 654-8657

PAIA is an excellent source for products and information for
(what I like to call:) small systems computer music.  They publish
a down home, yet techie, journal called "Electronic Musician".
The keyboards they sell are top quality units by the Pratt-Reed
Co. - an industry standard for such items.  The keyboards are
available completely "raw" or in various kits or as complete units
all the way up to a five octave programable MIDI controller - much
flexibility for the savvy user/builder.  Seems just what you're after.
OR:  Hot tip:
VERY "RAW" keyboards may be had from
Computer Products and Peripherals Unlimited
Box 204 
Newton, NH  03858
(617) 372-8637
four octaves for $39.00 (but keys and their switches on a frame is all 
you get -  good deal!  PAIA's circuit board for their MIDI controller is
$19.95 - an EPROM burner and some 1/4" teak and you're in business.)

As for the worth of such an endeavor in the face of proprietary
VLSI chips in the commercial products ... SURE!!!!
No-one has yet released a product with *expressive* control over the
envelope in REAL-TIME. (Digital synth at least).
That is sorely missing.
