PC MIDI Cable

[banneduser]

Hi, this one' been bugging me for the last hour or so. What's the correct wiring for the midi output from the 15 pin port on a soundcard.

I've seen a diagram on ucApps but can't find it again.

Searching on google just gives 5 pin din -> 5 pin din.

Cheers, Matt Carus

Hi.

That soundcard (Joystick)/midi port needs a special adapter cable or "soundblaster midi cable" for Google ;)

Like:

or

And as you can see it's not that special at all.. ;) Nice practice for midibo.. other DIY projects.

OK, cheers, that circuit looks familiar.

More parts to buy...

Hi

I made my MIDI cable from:

It don't have buffer on the midi out, but it works good for me. Without the buffer IC i was able to stuff the optocoupler and the other components in the housing for the DB15 connector  :)

Another question:

I didn't get hands on 33pF caps for the XT resonance circuit on the CORE in my eager to get the CORE running so i stuffed it with 2*22pF instead. Anyone see problems with that ?

Ok,

I once tried to stuff one of those circuits with buffer IC in to DB15 shell (point to point wiring) and gave up ;) Maybe I should have another attempt.. maybe eith that using transistors as buffer.

I don't know about those caps.. BUT It's simply microcontrollers external resonator clock, so If got it running with 22pF I don't see any reason to change those ;)
