[rec.music.synth] Mac MIDI interface

mdth@ur-tut.UUCP (Mike Thome) (09/15/87)

So I've got a Mac, a MIDI keyboard, some sequencing software, and the parts
for a cable to connect 'em all together - the problem is that I cannot find
a wiring diagram for the required cable ANYWHERE!  My understanding is that
the interace (mac<->midi) really is nothing but a cable with the right
connectors on the ends - if I'm wrong, feel free to correct me (:-).

Can anyone help??  If I get a reasonable answer, I'll post (to a mac list)
a nice document with pretty pictures showing how to do it... So *next* time
someone has to do it, they'll be able to find it in an archive somewhere.
	thanx,

A Mac<->midi interface usually consists of opto-isolators and an
external clock to clock the Mac's serial ports at the right rate for
MIDI.  MacTutor magazine had an article on building one a while back.
The August 1987 issue of MacTutor has an article giving the source of
a library of functions for dealing with MIDI data. That article
references the hardware article.
