    BiPort performs the following functions: • Acts as a SMPTE writer. The user may manually configure, start and stop the SMPTE writer from the BiPort’s front panel. The SMPTE signal appears at the SMPTE Out jack. • Acts as a SMPTE reader/regenerator. If the BiPort is not writing SMPTE, whenever a

    • Outputs MIDI Time Code (MTC) to the host. Whenever the BiPort is reading or writing SMPTE it will convert the SMPTE information to MTC. This MTC is transmitted to the host computer via the host serial cable. • Monitors the host port for SYSEX control information. This is where commands from the

    BiPort 2x4s INSTALLATION Installation for Stand-Alone Mode A typical stand-alone system set-up (see Fig. 1) might consist of a BiPort 2x4s, a tape deck, and a hardware MIDI sequencer. This set-up is connected as follows: • The tape recorder Tape (or Sync) Out is connected to the BiPort 2x4s SMPTE

    • The tape deck Tape In (or Sync In) is connected to the BiPort 2x4s SMPTE Out. • Additional MIDI devices may be directly connected to the BiPort 2x4s MIDI In-B, MIDI Out-B, MIDI Out-C and MIDI Out-D jacks. In this example, the BiPort 2x4s provides several functions: 1) it acts as a multi-port MIDI

    Selecting a PC Host Serial Port In order to operate as a PC MIDI Interface, the BiPort requires connection to a PC serial port. PC serial ports are also known as “COM” ports. The COM port configuration for each computer varies. Most computers have one or two COM ports, and some are configured to

    About the Serial Cables The BiPort 2x4s ships with two cables for connecting the BiPort to a host computer. One cable connects the BiPort to a standard PC serial port connector (male 9-pin DB-type); the other connects the BiPort to either a Macintosh modem or printer port. Both cables are standard

    Configuring Applications to Use BiPort 2x4s Once the drivers for the BiPort 2x4s have been installed, you will need to configure your MIDI applications to take advantage of the BiPort 2x4s drivers. The manner in which each application does this is different, so it is impossible to go over all

    What is MIDI Time Code (MTC)? MIDI Time Code (MTC) is the MIDI implementation of SMPTE. MTC was first standardized in 1987 as a method of synchronizing MIDI software and hardware sequencers, as well as drum machines. Later it was also adopted by digital audio recording software and hardware

    Black and white video frame rates were originally derived from the A/C line frequency of the indigenous country (e.g. 50 Hz in Europe, 60 Hz in the U.S.). In the U.S. when color video was introduced, part of the black and white frame information was used to encode the color information. The result

    encode these User Bits into the time code message without affecting the time code itself. Because there are 32 User Bits available, they can be further subdivided into 8 nibbles (one nibble = 4 bits), each of which can represent a binarycoded decimal (BCD) digit. A typical set of User Bits might

    At times, you may be given a tape with SMPTE already on it. The offset time on the tape you receive will affect the start time that you set for your MIDI sequencing. For example, if the time code on the tape starts at 02:00:00:00 (a 2-hour offset) and you need to start your sequence playing 3

    Sometimes you will be provided with a piece of source material that already has SMPTE on it. In that case, you are not required to record another SMPTE stripe and may instead read the SMPTE as is.

    Syncing to a SMPTE Stripe With a SMPTE stripe recorded on one track of your tape deck, you are now ready to sync to tape. Set your sequencer to SMPTE/MTC clock, making it a slave to the BiPort 2x4s. Since the BiPort 2x4s auto-detects the frame rate of incoming SMPTE, it is not necessary to set the

    Make sure your sequencer is set to receive MTC on the Windows driver that has MIDI Time Code coming over it. This driver is called “BiPort 24s Sync/Status”.
