Good, so you're not completely stupid after all.

Nope, 'fraid not.

It would appear so, as the above quote was a direct cut-and-paste (and just
to rub your nose in it further, here's your ORIGINAL message in its
ENTIRETY).

 OK, plans for a nice little MIDI box for your friend Al...

The following text explains how to build a MIDI interface for the
Sound Blaster. The circuit is my own design, but works just like
the commercialy available interfaces that retails for $60-$90.

Here is the list of parts necessary:

Qty.           Part

 1    Sharp PC900 or HP 6N138 opto-isolator
 1    DB15P (15 pin 'D' connector, male. like joystick connector)

 3    220 ohm resistors (2 for input, 1 for EACH output you need)
 1    3 conductor shielded cable (length is up to you)
 2    Female 5 pin DIN connector (1 for input, 1 for each output you need)
 1    PC board with pre-drilled holes (about 2" x 2" from Radio Shack)
      A few short lengths of hook-up wire

All of these parts, except the first 2, are available from Radio Shack.

Construction techniques are completely up to you, if you want to go
ultra-cheap, you don't even need a PC board or enclosure, and you could
use a MIDI cable you already have by cutting it in the middle. I used
a PC900 out of a non-working organ and cut the end off of a joystick I
didn't need and built the whole thing for about $4.00. Buying all the
parts new, and using an enclosure with built-in MIDI jacks may cost
about $20 or so.

Here is a diagram of the DB15P connector (looking at the solder side).

This is the circuit for the MIDI INPUT.

Don't overlook the two 220 ohm resistors.

Also, for cables longer than a few feet, connect pin 2 of the DIN to pin
5 of the 'D' connector.


The output circuit is much simpler.

                                  220 ohm resistor
To pin 12 of 'D' connector  To pin 5 of DIN con.

To pin 15 of 'D' connector  To pin 4 of DIN con.

Also, for cables longer than a few feet, connect pin 2 of the DIN to pin
5 of the 'D' connector.


This circuit has been built and tested by me, using Voyetra's SPJr, and
a cheap-o Casio keyboard. The input and output do work as shown here, but I
don't have any other MIDI devices to use to test using more than 1 output
device. Theoretically, it should work fine, but it has not been tested.
The chances of hurting anything by trying is slim and none.

This circuit DOES work, but I make no guarantees, nor will I be
held responsible for any damages you may cause from your use of
this information.

I can be contacted on:

MP> I put it to you, Mr Grimsley, that to relieve pressure on yourself for
MP> supplying bogus computer parts prices and to discredit me,

Excuse me?  There are at least 2 others posting in this area, who have
access to the same wholesaler's price list that I use, and in fact, they
have already verified that the prices I quoted earlier are indeed genuine.

MP> you edited my message,

Nope.

MP> accused me of plagiarism,

Nope.  I said "Does the term "plagiarism" mean anything to
you?".  Sure doesn't sound like an accusation to me, although if the
cap fits...

MP> and hoped that I would curl up in the corner.  Well, I'm not going to.

Sorry to disillusion you, but what you do is of no interest to me whatsoever.

MP> You had it going pretty well there, you had got one of your little buddies 
MP> to make up some fake messages and to back you up on the matter.

Ah, now I get it!  You're still trying to find out where we source our PC
components and accessories.  Nice try, but no cigar.

MP> But here, you've gone a bit too far. 

Nope.  In fact, I haven't even started.

MP> Now, I'm asking you to publicly retract your defamatory accusations, 

Nope.

MP> apologise for the mental anguish caused to me,

ROFL!  But that would imply that you actually had a brain...

MP> and to publicly acknowledge that you edited my message.

Unfortunately for you, the graphic evidence above (your OWN original
message) categorically proves otherwise.  Can I possibly interest you in a
large towel, so that you can wipe all that egg from your face?  :)
