Re: Devtronix and Octet MIDI Decoders
By Ron Yost

Hello all!

The Devtronix system was designed especially for pipe organs, and it
interfaces with the various switches in the organ manuals.  Each circuit
board handles 64 inputs/outputs and thus is perfect for 61-key manuals.
Mike Ames, myself, and several others have adapted it to operate book-
and roll-playing instruments, including huge 101-key Mortier organs and
Violano Virtuosos. The Devtronix system is not a "plug and play" system,
however .. much wiring and hand-soldering has to be done.

Devtronix' address:

        Devtronix Organs, Inc.,
        1823 Avondale Ave.,
        Sacramento, CA 95825
        916-971-9074

Pete Woodworth has found a new maker of Midi interface boards, Octet
Design Corporation.  (Thanks, Pete!)  This is a brand new system and, as
far as I know, none of us has tried it as yet.  It incorporates several
desired features lacking in the Devtronix system (not the least of which
is it's much less espen$ive!), though the higher power version drives
500 ma as does the Devtronix system.  Octet does have screw-terminal
blocks available for their system, a vast improvement over plain-jane
headers.  Also, the UM1 comes in a nice box, while the Devtronix system
is entirely bare-naked boards, which may or may not matter to you.

A further advantage is the Octet system is that it's much less expensive
than the Devtronix system.  The Devtronix system requires a separate
processor board for input and output ($250 each) -- the only difference
being the firmware EPROM.  Devtronix also requires separate input and
output boards ($125 each for 64 In/Out).  The whole system can get quite
expensive!

In contrast, the Octet UM-1-P (the higher-power version) is $279 for
the whole thing.  Very tempting indeed!  Now, how do we get a "group
evaluation" sample??  ;-)

The Chief-Engineer, Laurent Coray, is extremely helpful and courteous.
Also, they have a WEB site:

   http://www.octetdesign.com/

For info, if you lack WEB access:

   support@octetdesign.com
   Phone: (503) 261-2987  [Portland, Oregon, U.S.A.]

You will get a response from Laurent himself.

If anyone would like further information, as I have a lot of experience
with the Devtronix system, I'd be happy to help out.  Mind you, I have
used the system only with my self-designed Midi Fair Organ, and have no
experience with a "real" church pipe organ.

Take Care!
