IMPORTANT: Only select the “Merge All” feature if your
MIDI application allows only one input to be selected at a
time in its MIDI setup. The “Merge All” can affect SMPTE
sync performance adversely because the MIDI Time Code
(MTC) from the SMPTE port must be merged with any other
MIDI data that is coming in on In-A or In-B. This incoming
MIDI data can “jitter” the MTC and make the timing look
irregular to the receiving MIDI application.
Mac Driver/OMS Installation
The BiPort OMS Driver is designed to run with Opcode’s “Open Music
System.” You will need the OMS application to use the BiPort 2x4s as a
multiport MIDI device. If you do not have Opcode’s OMS installed, or if
you are not using an application that supports OMS, you will not be able
to use the BiPort 2x4s. This is available as a free download from
Opcode’s website, and you will find a link to it on the drivers page of
the Midiman website.
To Install the BiPort on your Mac, first attach one side of the supplied
Mac serial cable (or any standard Mac serial cable) to the jack labeled
“Host In,” and the other side to either the printer or modem port on you
computer (for more information, consult the sections of the manual
titled “BiPort Installation” and “BiPort to Host Connection”).
Make sure that OMS has been successfully installed. After you are sure
that OMS is properly installed, go to the Control Panel or Chooser under
the Apple Menu, and make sure AppleTalk is turned off (this is recom-
mended, although OMS will sense that it is on and prompt you to turn it
off).
Mac Driver Installation
If you are installing your BiPort driver and configuring OMS for the first
time, follow these instructions to configure OMS. If you have a studio
setup already created in OMS and wish to create a new studio setup,
skip to the section below entitled “Installing with an existing Studio
Setup.”
