[net.music.synth] MIDI INTERFACE FOR THE MACINTOSH

audrey@inuxi.UUCP (Audrey Burson) (10/30/85)

I am interested in using a MACINTOSH as a sequencer and to help program
and store voices for the DX7.  Is anyone familiar with a hardware and/or
software interface for the MAC?  Any information that may help me will be
appreciated!

                                                     Thanks,
                                                      Audrey B.

Pickup a copy of "Keyboard" magazine and you'll see ads for dozens of
hardware and software interfaces to the Mac. Doing it yourself is no
big deal either. The Mac's serial ports are easily converted into midi
ports with a few dollars of hardware. This "hardware" is just the
glue to go to/from midi's current loop to/from the Mac's rs422-like
levels. You can jam in an external clock at multiples of the 31.25k
baud rate and tell the Mac to clock on that.

CAVEAT: 31.23k baud could mean a char every 320uS; so interrupts
are your friend!
