MACMAN
™
MACINTOSH MIDI INTERFACE
The Macman MIDI Interface allows your Macintosh computer to
send and receive MIDI.
If your sequencing software does not include a "MIDI
Manager," you will need to acquire Apple's MIDI Manager or
Opcode's OMS. Both of these are a free download from either
company's website (apple.com or opcode.com).
In almost all cases the Macman does not need power because it
can draw current from the Mac itself. However, some Mac computers, like the Powerbook 500 series, cannot supply enough
power. In this case the Macman has a power connector on the
side for use with an optional 9 volt dc adaptor.
To install the Macman connect the included serial cable into the
Serial In connector on the Macman. Plug the other end of the serial cable into either the modem or printer port of your Mac -either port can be used. Just make sure the MIDI program you
are using is set to the same port into which your Macman is
plugged. Macman does support both the new 9 pin serial GEO
port and the old standard 8 pin serial port.
Macman operates in MIDI mode when the INTERFACE/THRU
switch on the right side of the unit is pressed In AND
a MIDI
application is being run. When the unit is properly activated in
this fashion, the red POWER LED will light, indicating that you
are in MIDI mode. The Macman is now able to send and receive
MIDI when addressed by a standard MIDI application.

The MIDI Data In and Out indicator LEDs are only operational
when the INTERFACE/THRU switch is IN and the red POWER
LED is lit. The MIDI LEDs will flash whenever MIDI data is
received or transmitted and can be very helpful when trouble
shooting your MIDI system. If the INTERFACE/THRU switch
is In and MIDI data is sent out from the computer, Macman's
MIDI Out LED will blink, indicating that data is being sent. If
your keyboard’s MIDI Out is connected to the Macman MIDI In
and keys are played, the MIDI In LED should blink indicating
that data is being received.

Typically, the Macman's MIDI In should be connected to the
MIDI Out of your keyboard. The Macman's three MIDI Out
jacks are identical. You can connect any of your instruments'
MIDI Ins to any of these MIDI Outs.
If you need to use a printer or a modem that is connected to
your computer through the Macman Interface, make sure the
INTERFACE/THRU switch is Out. When this switch is Out,
the Macman is bypassed, and whatever is plugged into the
Macman's Serial Out will be connected directly to the computer. If you have run a MIDI application and now wish to use
your printer or modem, you may need to restart your computer in order to reset the port. When the INTERFACE/THRU
switch is Out, the Macman acts as a MIDI Thru box by connecting its MIDI In to all three of its MIDI Outs.
