mikee Posted August 30, 2009 Report Share Posted August 30, 2009 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 :)MIDI_mod.JPGMIDI_mod.JPG Quote Link to comment Share on other sites More sharing options...
TK. Posted August 30, 2009 Report Share Posted August 30, 2009 It even works without a buffer:http://www.ucapps.de/mbhp/mbhp_midi_gameport.gifBest Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
mikee Posted August 30, 2009 Author Report Share Posted August 30, 2009 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.
