is a 'correct' MIDI interface really needed?????

3 posts in this topic

PC owners have to use a MIDI interface cable so that they can interface to a MIDI machine such as MBox64.

The core must therefore have a complimentary MIDI interface including an opto-isolator etc etc.

But as the opto-isolator is only present to prevent ground loops (which usually only occours when lots of gear is used) and affords no so-called 'protection' for the core pic, I wonder why on earth spend out on the things which are not required?

Surely a simple buffer between Pic and Games port would suffice???

Cheers all  :)

Cheers for the reply.

It makes sense to me: use the least to get the same (or better) result. Its surprising how many think the opto-isolator is there to protect expensive chips.

Interesting project you have there Thorsten, thanks a lot.
