PART 1: Overview and Installation Studio 4 Manual 1 PART 1: Overview and Installation 2 Opcode Systems, Inc. CHAPTER 1: Getting Started OVERVIEW OF THE STUDIO 4 Opcode's Studio 4 is a multi-port Macintosh MIDI interface with a built-in SMPTE timecode generator and SMPTEto-MIDI timecode converter. MIDI features of the Studio 4 include: · Eight independently addressable MIDI inputs and outputs--this allows access to 128 separate MIDI channels with programs that support either OMS or Mark of the Unicorn's MIDI Time PieceTM. Networking--connect up to three additional Studio 4's for 512 separate MIDI channels. The MIDI Time Piece and Studio 4 can be part of the same network. Built-in MIDI routing, channelizing and muting. OMS patch compatibility--OMS patches processed by the Macintosh may be used with the Studio 4. OMS patches allow MIDI data to be split, transposed, modified, and mapped in many useful ways. Standard (1MHz) and Fast communication speeds. A MIDI activity indicator for each MIDI port. · Front panel thru switches--these let you use external peripherals (such as printers or modems) without changing cables. Timecode functions of the Studio 4 include: · · · · · SMPTE Time Code generation (five frame rates). SMPTE-to-MIDI Time Code conversion. SMPTE-to-Direct Time Lock conversion (both DTL and DTLe). Jam Syncing (rewrites fresh SMPTE when locked). Flywheeling (remains locked despite dropouts or other short SMPTE errors). · · · The Studio 4 uses the Opcode MIDI System (OMS) and the Studio 4 OMS driver software to control all mapping, channelizing, routing and timecode functions. HOW TO READ THIS MANUAL This manual does not attempt to teach fully the fundamentals of MIDI or SMPTE operation. A brief timecode overview is presented at the end of this chapter, but if · · Studio 4 Manual 3 PART 1: Overview and Installation you're new to either of these standards, you should read magazines specializing in music technology, or purchase introductory MIDI and SMPTE books from your local bookstore or music dealer. Also, you should be familiar with basic Macintosh operations. If you're not, please read the Macintosh manual before using the Studio 4. This manual discusses how to connect, set up and use the Studio 4--it describes Studio 4 operations at the time of its printing. However, updates and changes may occur. Always look for hardware and software change information in the Read Me folder on your master program disk. The Studio 4 uses the Opcode MIDI System (OMS) and the Studio 4 OMS driver software to control all mapping, channelizing, routing and timecode functions. If you're already familiar with OMS, you can read this manual straight through. NOTE: If you have never used OMS, read the first three chapters in this manual, then read the OMS manual before installing OMS and reading Chapter 4. Pay particular attention to the OMS manual's discussions of installation, defining devices in your studio and creating a current OMS Studio Setup document. This manual is divided into three parts: · Part 1: Overview and Installation (Chapters 1-4)--This part discusses the Studio 4's front and rear panels and will help you to integrate the unit into your studio. It concludes with a · · chapter describing software installation and setup. Part 2: Using The Studio 4 (Chapters 5-10)--This part explains how to set the Studio 4 internal state and use its SMPTE features. Part 3: Appendices This part includes a troubleshooting section, details on networking the Studio 4 with a standard MIDI interface, and the Studio 4 specifications. THE STUDIO 4 PACKAGE Your Studio 4 package contains the Studio 4, an AC adapter, two 12' serial cables, 4 rubber feet, rack-mount screws, OMS and Studio 4 software, an OMS manual, this Studio 4 manual and a registration card.

NOTE: Technical support hours are subject to change. synchronize the playback of separate audio decks, video decks and computers. Using SMPTE requires two separate actions: · Generating the SMPTE Time Code and recording it onto tape (a process often referred to as "striping"). Reading the SMPTE Time Code off the tape and using it as a master timing source for synchronizing playback of other tape machines and computers. · TIMECODE BASICS The operational portions of this manual assume you're familiar with SMPTE Time Code, MIDI Time Code, and Direct Time Lock. If you're not, you should read this section to develop a basic understanding of synchronization and the various timecode formats. Consult music technology magazines or introductory books if you need more information about any of these topics. There are two types of SMPTE Time Code: Longitudinal Time Code (LTC), and Vertical Interval Time Code (VITC). LTC is recorded on tape tracks that run linearly across the length of the tape. This format is recorded on audio tape or on the audio track of a video tape. VITC is recorded within the video portion of a video tape. Since different video systems run at different speeds (or "frame rates"), the SMPTE format also specifies a number of different rates. The Studio 4 will both generate and read SMPTE Time Code in the LTC format. If you have a tape striped with VITC, you'll need to use either a VITC-to-LTC converter or a VITC-to-MTC converter such as Opcode's Studio AV. The Studio 4 supports five SMPTE frame rates. These rates are: · · 24 Frames/second--Film frame rate. 25 Frames/second--EBU (European) television frame rate. SMPTE Time Code SMPTE Time Code is an international timecode standard created by the Society of Motion Picture & Television Engineers. It specifies a format for recording digital timing information onto magnetic tape; this timing information is divided into hours, minutes, seconds and frames. By using SMPTE Time Code (often referred to simply as "SMPTE"), you can Studio 4 Manual 5 PART 1: Overview and Installation · · · 29.97 Drop Frame--NTSC (North American) color television frame rate. This format runs at 30 Frames/second, but has the first two frames dropped every minute, except at minutes 0, 10, 20, 30, 40 and 50. 29.97 Frames/second (Non-Drop)-- Used to sync to NTSC color television without dropping frames. SMPTE time does not match real-time, but playback pitch is unaffected. 30 Frames/second (Non-Drop)-- Original NTSC black and white television standard. Often used in audioonly situations since there are no dropped frames and the SMPTE time is equal to real time. Enhanced Direct Time Lock (DTLe), which provides synchronization accuracy equal to MIDI Time Code. The Studio 4 will convert SMPTE timecode (recorded at one of the five supported frame rates) to either MIDI Time Code or one of the Direct Time Lock formats. Figure 1.1: this will not print - it's in white color MIDI Time Code and Direct Time Lock MIDI computer software cannot read SMPTE Time Code directly off a tape, so the code must be converted into a format that the computer can understand. This format is called MIDI Time Code (MTC). The converter then sends MTC (which retains SMPTE's hour/minute/second/ frame timing information) to the computer to control the playback of MIDI sequencers. You use MIDI Time Code to synchronize your computer sequence to a master SMPTE timing source. Direct Time Lock (DTL) and Enhanced Direct Time Lock (DTLe) are alternate MIDI synchronization formats developed by Mark of the Unicorn for their Performer sequencer. Very old versions of Performer require DTL to sync to tape. Newer versions of Performer use 6 Opcode Systems, Inc.

MIDI Ports 7/15 and 8/16 These two pairs of MIDI ports are on the front panel to facilitate quick, temporary connection of synthesizers, controllers or other MIDI devices. MIDI ports are discussed in detail in "The Studio 4 Rear Panel" section later in this chapter. Front panel MIDI output ports 7/15 and 8/16 are duplicates of MIDI output ports 7/15 and 8/16 found on the rear panel. If you connect a device to both a front panel MIDI output and its corresponding rear panel output, MIDI data will be sent to both devices. Front panel MIDI input ports 7/15 and 8/ 16 are in addition to the 6 MIDI inputs found on the rear panel. MIDI input ports 7/15 and 8/16 are not duplicated on the rear panel. MIDI Out LED's This row of green Light Emitting Diodes (LED's) indicates MIDI data is leaving one or more of the Studio 4's eight MIDI output ports. 1MHz/Fast Switch Use this switch to select a communication speed. 1MHz is the standard MIDI interface speed required by most MIDI software. Fast speed increases MIDI throughput, thereby increasing the number of simultaneous MIDI channels. Check your MIDI application manuals to see if they support Fast mode. Opcode products that support Fast mode include Vision, Studio Vision and EZ Vision.

CHAPTER 2: Panel Descriptions SMPTE IN Jack This jack receives SMPTE timecode from a tape deck or other SMPTE source. The Studio 4 converts the SMPTE input into the MIDI format specified by the Stripe SMPTE window (see Chapter 10). (See "Computer Connections" in Chapter 3). You cannot use the "A" port for networking. As a matter of convention, you may wish to connect "A" to the Modem port, leaving the "B" port free for connecting the Macintosh's Printer port, another Macintosh or another Studio 4. Attach external peripherals (such as a printer or modem) to the "A THRU" and/ or "B THRU" ports on the Studio 4. You can use these peripherals without disconnecting the Studio 4 from the Macintosh. Simply use the corresponding front panel Thru switch to route data arriving at one of the Studio 4 computer ports to its corresponding THRU port (see "Thru Switches" earlier in this chapter, and "Computer Connections" in Chapter 3). SMPTE OUT Jack This jack outputs SMPTE timecode generated (or regenerated) by the Studio 4. This jack is normally connected to the line input of a tape deck. You may set the SMPTE output level in the Stripe SMPTE window (See Chapter 10). Computer Ports and Thru Ports The Studio 4 does not implement the traditional Macintosh MIDI interface concept of a "Printer port" and a "Modem port". Older interfaces have a limit of 32 addressable MIDI channels; 16 on the Printer port and 16 on the Modem port. Each Studio 4, however, can address up to 128 separate MIDI channels spread across its two serial inputs. These input ports are labeled "A" and "B". The inputs (with the little Macintosh icons) connect to the Macintosh using standard 8-pin mini-DIN cables (supplied by Opcode with the Studio 4). You may connect the Studio 4 "A" port to either the Macintosh Modem port or Printer port. You may connect the Studio 4 "B" port to the Modem port, the Printer port or to another Studio 4 to form a network. You can also connect two Macintosh computers to one or two Studio 4's MIDI OUT Connectors Connect these eight ports to the MIDI IN ports of your MIDI devices. Each port has dual numbers that correspond to the position of the 1-8/9-16 switch on the front panel. MIDI output ports 7/15 and 8/16 are duplicated on the front panel. If you connect devices to both a front panel MIDI output and its corresponding rear panel output, MIDI data is sent to both devices. MIDI IN Connectors Connect these six ports to the MIDI OUT ports of your MIDI devices. Each port has dual numbers that correspond to the posi- Studio 4 Manual 9 PART 1: Overview and Installation tion of the 1-8/9-16 switch on the front panel. Two additional inputs are on the front panel. ABOUT THE INTERFACE CABLES The Studio 4 comes with standard 8-pin mini-DIN cables. If you are using cables other than the ones supplied with the Studio 4, please ensure that they are 8-pin mini-DIN. You should use only high quality shielded MIDI and audio cables when operating your Studio 4 or any other professional audio equipment. 10 Opcode Systems, Inc. CHAPTER 3: Hardware Installation Use the rackmount screws (provided) to mount the Studio 4 in a standard 19" equipment rack as shown in Figure 3.1. COMPUTER CONNECTIONS-- ONE STUDIO 4 You may connect the Studio 4 to either the Macintosh's Modem port, Printer port, or to both.

Attach the four rubber feet (provided in this package) to the bottom of the unit to prevent it from sliding. Single Port Connection Single port connections are useful if you frequently use a Macintosh serial port for non-MIDI purposes (such as printing) while running MIDI applications. You can use the spare Macintosh serial port without using the Studio 4's front panel MIDI/ THRU switch. You may connect either the Studio 4's "A" port or "B" port to either the Macintosh Modem or Printer port. The "B" port, unlike the "A" port, can also be used to connect an additional MIDI Interface. For this reason (and as a matter of convention) you may with to connect "A" to the Mac's Modem port, leaving the "B" port free for later connection to either the Mac's Printer port (discussed in the "Dual Port Connection section") or to another interface (discussed in the "Computer Connections--Networking" section). POWER CONNECTION Place the tip of the power supply cord into the power jack on the far left side of the rear panel, then plug the power supply into a standard 120VAC, 60Hz electrical outlet.

You can connect an additional external peripheral (such as a modem) to the "A THRU" jack on the Studio 4 and switch it in or out from the front panel. Figure 3.4: Dual Port Connection NOTE: In a two cable system, such as shown in Figure 3.4, use the Network Routing window to distribute data between ports (see Chapter 6). Connecting Two Macintosh Computers Two Macintosh computers may share one Studio 4 by connecting one Macintosh to the Studio 4 "A" port and connecting the other Macintosh to the Studio 4 "B" port. MACINTOSH MACINTOSH Dual Port Connection Use a dual port connection if you need increased MIDI "throughput" (for example, your MIDI data is densely packed with notes, continuous controls, System Exclusive messages and MIDI Time Code). It's a good idea to always use a dual port connection when you're synchronizing MIDI playback with SMPTE timecode. You may connect the Studio 4's "A" port to either Macintosh serial port. Similarly, you may connect the "B" port to either the Modem or Printer port. Figure 3.4 illustrates a common dual port connection.

Do not check this option if you're not using two computers to control the Studio 4. Multiple Macintosh Caveat Use only one computer at a time to initiate actions that change a Studio 4's internal state--always wait at least 1 second before initiating any state-changing actions from a different computer. Actions that cause the Studio 4 to change state include: · Clicking anywhere in either the Network Routing window or the Routing, Channelizing and Muting window. Switching, opening or quitting applications. Performing Galaxy patch transfers. Making different windows active in OMS Setup and the Studio Patches Editor. Using the Enable Inputs dialog in Vision. COMPUTER CONNECTIONS-- NETWORKING A network is defined as the connection of one or two Studio 4's to a single Macintosh serial port. The Macintosh has two serial ports, so it can support two networks. Since each network can contain either one or two Studio 4's, you can connect up to four Studio 4's to a single Macintosh for a maximum total of 512 MIDI channels. NOTE: When networking two Studio 4's, always connect their "B" ports together. Connecting Two Studio 4's to a Macintosh There are many possible ways to connect two Studio 4's to a single Macintosh. You can connect them as one network on a single port, as two separate networks, or as a 2-cable network. With two Studio 4's, you can access up to 256 independent MIDI channels. One Network/1-Cable The first option is to connect both Studio 4's in a single network as shown in Figure 3.7. Set each Studio 4's front panel 1-8/9-16 switch as indicated. You may connect the network to either Macintosh · · · · If you use different computers to change the Studio 4's internal state too quickly, Studio 4 Manual 13 PART 1: Overview and Installation serial port. The advantage of this connection is that you retain a free Macintosh serial port. The disadvantage is that all MIDI and timecode communications occur over a single Macintosh port--you could get data overloads if you have a very dense MIDI data stream and are syncing to SMPTE timecode.

This is similar to the one network/1-cable configuration, except you connect a second cable between the last Studio 4's "A" port and the unused Macintosh serial port as shown in Figure 3.9. Set each Studio 4's front panel 1-8/9-16 switch as indicated. This configuration provides optimum flexibility. You can balance the MIDI data stream (unlike the one network/1-cable connection) and you can use the Studio 4's internal routing to send MIDI data between interfaces (unlike the two network connection). Use the Studio 4's front panel THRU switches to access external peripherals.

Set each Studio 4's front panel 1-8/9-16 switch as indicated. With this connection, you can balance the MIDI data stream between the two Macintosh serial ports using the Network Routing window (discussed in Chapter 6). You cannot, however, use internal routings to send MIDI data from one box to another (as discussed in Chapter 7).
