(these will light in Stand-Alone mode when accessing the Remote Control software). As an interface, the BiPort 2x4s acts very sim- ilar to the Midiman Portman 4x4/S and other MIDI/SMPTE interfaces. In MIDI Interface mode, the BiPort performs the following functions: •... -
Page 9: Functions Shared By Both Modes
• 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 seri- al cable. • Monitors the host port for SYSEX control information. This is where commands from the Remote Control software are received. -

displays the format to the “Format” LEDs on the BiPort front panel. Automatic format detection will take between 3 and 31 frames, depend- ing on the incoming format and the value of the first SMPTE frame received. When using the BiPort with a sequencer program synced to MIDI Time Code, at least 3 to 5 seconds of pre-roll are recommended for proper synchronization. -

Page 13: Biport 2X4S Installation
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 con- nected as follows: • The tape recorder Tape (or Sync) Out is connected to the BiPort 2x4s SMPTE In. - Page 14 SMPTE In. Typical MIDI Interface System Set-up - Fig. 2...

• 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 interface between the host computer and the connected MIDI keyboards and sound modules;... -
Page 16: Selecting A Pc Host Serial Port
Selecting a PC Host Serial Port In order to operate as a PC MIDI Interface, the BiPort requires connec- tion 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 have 4 or more. -

Move the connecting MIDI loopback cable to match the setting on the diagnostic program screen and re-run the tests to make sure that all of your BiPort inputs and outputs are working properly. Mac Diagnostic Application Included with your BiPort 2x4s is Remote Control and Diagnostic soft- ware that enables you to configure and control your BiPort 2x4s SMPTE functions directly from your computer, as well as the diagnostic test for basic BiPort functionality. -

• The BiPort is defective. This is extremely rare as the BiPort units are tested rigorously at the factory before shipping. If you think this is the case, please contact MIDIMAN Technical Support. 4. Receive Interrupt Test This test verifies the reception of data from the BiPort under interrupt (IRQ) control. -
Page 22: Windows 98 Installation
On the included software diskette, Midiman supplies the Windows drivers that enable the use of the BiPort 2x4s with Windows MIDI applications. In order to communicate with the BiPort 2x4s, the Windows driver needs know what serial (COM) port you are connecting to the BiPort 2x4s. -

Page 35: Configuring Applications To Use Biport 2X4
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 possible scenarios here. -
Page 36: Smpte/Midi Time Code Tutorial
In order to route data between the application and specific ports on the BiPort 2x4s, select (from within your application) the appropriate drivers of the above list. Many newer applications (Cakewalk Pro Audio for Windows, for example) will allow you to select and access all the BiPort 2x4s ports within the same session. -
Page 37: What Is Midi Time Code (Mtc)
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 soft- ware and hardware sequencers, as well as drum machines. Later it was also adopted by digital audio recording software and hardware manu- facturers as a method of synchronizing to audio and video gear. -
Page 38: What Frame Rate And Settings Should You Use
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. -
Page 39: Smpte Offset
The BiPort 2x4s User Bits can be set via the Remote Control software and may be displayed with some outboard device such as the MIDIMAN SMPTE Time Window. The User Bits are also transmitted via MIDI message to the MIDI application that you are using. -
Page 40: Flywheeling
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 minutes, 30 seconds into the work, you should set the sequencer start time to 02:03:30:00. - Page 41 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. If, on the other hand, your source material has no current time code encoded you will need to record your own SMPTE time code to one of the tape’s tracks.
- Page 42 use noise reduction when recording or playing a SMPTE sync track. 8. Click on “Stop Writer” to stop the SMPTE code. You are now set to begin recording the SMPTE stripe. 9. Take the tape deck out of pause. Allow the tape to pre-roll for at least 10 seconds.
-
Page 43: Syncing To A Smpte Stripe
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 frame rate of the BiPort when syncing. -
Page 44: Trouble-Shooting
Trouble-Shooting If you are having problems using your BiPort 2x4s, it is probably a good idea to re-read this manual and make sure you have properly installed the interface.
