CH 1: OVERVIEW AND
INSTALLATION
INTRODUCTION TO THE OPEN MUSIC SYSTEM™ (OMS)
Opcode’s Open Music System (OMS) is a set of extensions and programs that bridge the gap between MIDI applications and MIDI hardware. It has many functions and features:
• OMS acts as a central MIDI driver
OMS-compatible applications use OMS to communicate with all of your MIDI hardware (such as synthesizers, drum machines, effects devices, or MIDI controllers).
• OMS provides a central location for defining and storing a detailed description of your MIDI studio
Use the OMS Setup application to create a Studio Setup document, in which you store a detailed description of the MIDI devices in your studio—including their names, their MIDI channels, and how they’re all physically connected.
All OMS-compatible applications reference this Studio Setup document. So, if you change your studio in any way, simply modify your
Studio Setup document and all compatible applications are immediately aware of the change.
• OMS provides a patch name management tool
Use this tool, appropriately called the Name Manager, to store the names of all the patches in your MIDI devices and provide those names to your OMS-compatible applications.
• OMS handles all your computer’s internal MIDI timing
This allows you to run multiple OMS-compatible applications simultaneously and in perfect synchronization.
OMS 2.3 for Macintosh Ch 1: Overview and Installation - 1 -
• OMS gives you access to hundreds of MIDI channels
The actual number of MIDI channels that OMS can access depends on which MIDI interface(s) you use.
Standard MIDI interfaces (such as Opcode’s MIDI Translator) access
16 total MIDI channels. Multiport MIDI Interfaces (such as Opcode’s
Studio 4 or Studio 5) access 16 MIDI channels on each pair of MIDI
In/Out jacks. So, for example, since a Studio 5 has 15 pairs of MIDI
In/Out jacks, it can access 240 total MIDI channels.
For more information, see your MIDI interface manuals.
ABOUT THIS MANUAL
This manual assumes that you’re familiar with basic Macintosh operations. If you’re not, please read your Macintosh manual before installing or using OMS.
Also, you should have a basic understanding of MIDI. If you don’t, you may wish to purchase one of the many basic MIDI reference books available from your local book store or music retailer.
This manual accurately describes OMS operations at the time of its printing. However, updates and changes may occur. Always look for the latest information in the
Read Me
files on your master program disk.

This manual does not discuss the Name Manager. Although the
Name Manager is part of OMS, its services are available only from within OMS-compatible applications and not from within the OMS
Setup application. Therefore, Name Manager information is contained within your OMS-compatible application manuals.
Also, OMS supports a wide variety of MIDI hardware configurations. Because many of these configurations are of interest to a small percentage of users, Opcode documents them in special on-line documents called
Technical Publications
. These publications address specific topics not covered in the written manual.
You can download the latest Technical Publications for OMS (or any other Opcode products) from Opcode’s World Wide Web site at:

This manual uses a shorthand technique to invoke various menu items. For instance, this manual might say:
“Choose
Studio>New Patcher
.”
What this means in plain English is, “choose the
New Patcher
command from the
Studio
menu.” Although the shorthand technique results in sub-standard grammar, it’s easier to read and decipher than a complete sentence because it displays the menu’s hierarchical structure plainly and simply.

INSTALLING OMS
Before you install OMS, you should:
• Connect your MIDI interface to your Macintosh (as described in your MIDI interface manual).
• Connect your MIDI devices (synthesizers, drum machines, effects units) to the MIDI interface, then turn them on.
There is an installer program on your OMS master disk or CD-ROM.
To install OMS: a b
Insert your master disk (or CD-ROM) and double-click the OMS Installer icon.
Answer each question as prompted by the installer application.
The installer places all the necessary OMS files onto your hard disk automatically.
WHAT’S INSTALLED
The Installer places all the necessary OMS files onto your hard disk automatically. After running the Installer and restarting your Macintosh, you can begin to use OMS.
The following sections list exactly what files the Installer places onto your hard disk and where it places them.

EFINITIONS
If you are updating from an older version of OMS, your previous
Studio Setup documents will be read by the new OMS Setup application.
?
CAUTION: Do not relocate or rename any files or folders that the
Installer places in the System Folder. You may delete unnecessary
files, but some files are essential for OMS operation. See Software
for more information.
Here is an overview of the OMS file layout:
• The Open Music System extension is placed into the Extensions folder.
• A folder named “OMS Folder” is created within the System Folder and OMS drivers are placed inside it.
• OMS applications are placed inside the “OMS Applications” folder that, depending on the installer, resides either at the top-level of your hard drive or in a folder named “Opcode.”
You can move the applications folder, but the extension and OMS
Folder must remain in their initial locations.
This section describes each file that the installer could possibly place on your hard disk. If, after reading the definition, you are sure you won’t need the file, you can throw it away. For instance, if you don’t have a Studio 3 interface, there is no reason to have the Studio 3
OMS Driver on your hard drive.
Future releases of OMS may add new files or features, so consult any
Read Me
documents contained on your master disk.

There are two methods for defining a Studio Setup document:
• Easy Setup
This automated procedure is invoked when there is no current
Studio Setup document and an OMS-compatible application is opened. In general, it’s a menu-driven setup procedure and, as such, is not discussed in this manual.
Remember, Easy Setup was designed to be a “quick and dirty” way to get going. If you have a complicated studio configuration (for example, devices connected via MIDI Thru jacks, or devices whose input and output port numbers aren’t the same), you will need to use the OMS Setup application to create a custom Studio Setup document.
• Custom Setup
If you need a higher degree of control, you can use the OMS Setup application to create customized Studio Setup documents. This is the procedure that’s described in this manual.
Ch 1: Overview and Installation - 9 OMS 2.3 for Macintosh
CH 2: CREATING A NEW STUDIO
SETUP DOCUMENT
This chapter teaches you to use the OMS Setup application to create a new Studio Setup document.
WHAT IS A STUDIO SETUP DOCUMENT?
A Studio Setup document is an exact model of your MIDI Studio. A fully configured Studio Setup document contains information about:
• MIDI interfaces connected to your Macintosh (such as an Opcode
Studio 64X or Studio 5).
• MIDI cards installed inside your computer (such as a MacProteus™ or SampleCell™).
• Software-based synthesizers and other “Virtual Synthesizers” (such as Apple’s QuickTime Musical Instruments).
• MIDI devices connected to MIDI interfaces (such as synthesizers, drum machines, effects devices, and MIDI controllers).
Additionally, a Studio Setup document contains information about how all this hardware is physically connected.
You can create and store any number of Studio Setup documents to describe any number of studios or studio configurations, but OMS can reference only one Studio Setup document at a time. This is called the current Studio Setup document.
Once you’ve defined a current Studio Setup document, OMS knows each instrument’s name, port, MIDI reception channel(s), Device ID and many other details. This information is provided to all OMScompatible applications. Within these applications, you simply select and work with devices by name—OMS handles the rest. Any time you change your current Studio Setup document, OMS automatically provides the updated information to all your OMScompatible applications.

AppleTalk is a Macintosh communication protocol for local area networks (LANs). Many laser printers require AppleTalk to communicate with your Macintosh. Unfortunately, AppleTalk can interfere with MIDI data arriving at either the modem port or the printer port.
In general, you should choose to turn off AppleTalk whenever you plan to record or play MIDI data using an OMS-compatible MIDI application. The exception is if you need to print from a MIDI application, such as Opcode’s Overture (a music notation program).

A
Multiport MIDI Interface
This example shows a Studio 5 multiport interface connected to the modem port.
B
MIDI ports on a multiport MIDI interface
Multiport MIDI interfaces display each of their MIDI ports in the
Studio Setup document.
By default, if OMS Setup can’t auto-detect a specific MIDI device, it creates an undefined MIDI device on each port.
If you have only a standard MIDI interface (such as a MIDI Translator II or Studio 3), then the Studio Setup document won’t contain any port numbers for that interface.
Ch 2: Creating a New Studio Setup Document - 16 OMS 2.3 for Macintosh
C
Standard MIDI interface
This example shows a standard MIDI interface (named “Std. Interface, Printer”) connected to the printer port.
By default, OMS Setup connected a single undefined MIDI device
(named “Printer”) to the interface. The following topic contains more information about undefined MIDI devices.
D
Undefined MIDI devices
Not all MIDI devices are capable of identifying themselves to OMS
Setup. OMS Setup has no way of detecting what other MIDI devices are connected to your MIDI interface (or even if any are actually connected). Therefore, it creates a generic undefined MIDI device on each MIDI port for which it doesn’t auto-detect a device. You can recognize an undefined device by its question mark icon.
See Chapter 3: Defining MIDI Devices to learn how to define MIDI
devices in a Studio Setup document.
E
Defined MIDI device
When a device is “defined,” it means that OMS knows its name,
MIDI channel, and all its other MIDI attributes. Defined devices can also be given one of numerous different icons, which appear in the
Studio Setup document.
You can define devices manually (as discussed in Chapter 3: Defining
MIDI Devices) or OMS may automatically detect some MIDI devices
and create default definitions for them.
F
MIDI cables (signal flow)
The connecting lines indicate MIDI cables and the arrows indicate the signal flow direction.
By default, OMS Setup assumes you have a pair of MIDI cables connected to each undefined MIDI device.
In Chapter 4: Connecting Devices in the Studio Setup Document, you’ll
learn how to modify the Studio Setup document connections so that they mirror your actual MIDI studio.

CONFIGURING OMS DRIVERS
Now that you have a Studio Setup document that recognizes all your
MIDI interfaces and MIDI cards, you’ll need to configure their OMS drivers. In general, most Opcode interfaces come with manuals that describe how to configure their OMS drivers. The following sections contain information about configuring a few of the other types of
OMS drivers.

IAC D
RIVER
The IAC (Inter Application Communication) driver provides a means for various OMS-compatible MIDI applications to communicate with one another.
The IAC driver provides up to 4 busses, which any application may send to and/or receive from. For example, using one bus, you can run Digidesign’s Pro Tools and Opcode’s Vision programs simultaneously -- using one to control the playback of the other. Using another bus, you could send MIDI information from Vision to
Opcode’s Max, using its programmable modules to perform sophisticated MIDI processing.
?
IMPORTANT: This driver is not installed as part of OMS’ Easy installation process so, if you wish to use it, you must perform a Custom installation.
To define and name busses: a
In your OMS Studio Setup document, double-click the IAC Driver icon to open its
Configuration dialog box.
b
Type a name for each bus you wish to activate, then click

Figure 14 shows the various MIDI characteristics contained in the
MIDI Device Info dialog box. These are:
A
Is controller
check box
Check this check box if your MIDI device is a MIDI controller (such as a keyboard, MIDI guitar, MIDI drum pads, and so on).
This check box is automatically set when you define a manufacturer and model, but you can override the default setting.
B
Is multitimbral
check box
Check this check box if your MIDI device is multitimbral.
Multitimbral means that the device is capable of receiving MIDI data on more than one channel. Most modern synthesizers are multitimbral—many early MIDI synthesizers are not.
This check box is automatically set when you define a Manufacturer and Model, but you can override the default setting.
C
MIDI Receive Channels
Check all the MIDI channels on which your MIDI device receives
MIDI data.
For example, if your synthesizer is set up to receive only on MIDI channels 1 through 6, check only the boxes numbered 1 through 6.
If the Is multitimbral check box is not checked, your device can receive on only one MIDI channel, so you can check only one box at a time.
D
Device ID
Set the Device ID numerical to match the Device ID setting on your
MIDI device.
If the Is multitimbral check box is not checked, the Device ID is automatically set to match the MIDI Receive Channel. You can enter a different Device ID number if you wish.
See your MIDI device manual to learn how to view (or change) its
Device ID.

MIDI Synchronization check boxes
Check the MIDI Time Code check boxes only if: 1) your MIDI device sends or receives MIDI Time Code, and 2) you intend to use it to synchronize that MIDI device to your OMS-compatible MIDI sequencer.
Check the MIDI Beat Clock check boxes only if: 1) your MIDI device sends or receives MIDI Beat Clock, and 2) you intend to use it to synchronize that MIDI device to your OMS-compatible MIDI sequencer.
Many drum machines and synthesizers with built-in sequencers are able to send and receive MIDI Beat Clock.
Check the MIDI Machine Control check boxes only if: 1) your MIDI device sends or receives MIDI Machine Control, and 2) you intend to use it to synchronize that MIDI device to your OMS-compatible
MIDI sequencer.
See your MIDI device manuals to learn whether or not they support any of these synchronization methods.

DELETING MIDI DEVICES
If your Studio Setup document contains MIDI devices that aren’t in your actual MIDI studio, you can delete them from the document.
This is particularly useful for:
• removing undefined devices created by the OMS Setup application
• removing devices no longer contained in your MIDI studio.
To remove the unused MIDI devices from your Studio Setup document: a

In this chapter, you’ll connect all the MIDI devices in your Studio
Setup document to mirror the way the actual hardware is connected in your studio.
When you finish connecting device icons, your Studio Setup document will function as a graphic representation of the MIDI components in your studio.

IMPORTANT: The Studio Setup document should reflect, as accurately as possible, the actual connection of MIDI devices in your studio. OMS-compatible applications derive their knowledge of the devices in your studio from the Studio Setup document.
CONNECTING MIDI DEVICES TOGETHER
To “connect” MIDI devices together in a Studio Setup document, simply drag one device icon onto another.
Using this technique, you can connect...
• MIDI devices to MIDI interfaces, as discussed in Connecting Devices to a MIDI Interface (pg. 30) .
• MIDI devices to other MIDI devices. This technique is used when
“daisychaining devices using MIDI Thru jacks, as discussed in Using

CONNECTING AND DISCONNECTING MIDI CABLES
The last step in defining your Studio Setup document is to connect or disconnect MIDI cables to reflect the actual cabling in your real MIDI studio.
The Studio Setup document represents each connected MIDI device with a pair of lines running in and out of its left side. These lines represent MIDI cables and the arrows indicate the direction of MIDI data flow.

Figure 22 contains a 1-in by 2-out MIDI interface. Obviously this
Studio Setup document is wrong—the MIDI interface contains only
one MIDI In jack, yet the Studio Setup document shows two synthesizers sending MIDI data to the interface.
This document shows TWO MIDI cables connected to the interface’s single MIDI In port—obviously an incorrect representation.

Ch 4: Connecting Devices in the Studio Setup Document - 31 OMS 2.3 for Macintosh
The actual MIDI studio has the K2000’s MIDI Out jack connected to the MIDI interface and both device’s MIDI In jacks connected to the
MIDI interface. To modify your Studio Setup to show the correct connection: a
Click the MIDI Out arrow to the left of the Proteus/2.
OMS Setup removes the cable from the Studio Setup document. Your Studio
Setup document now accurately reflects the cabling in your MIDI Studio.
DISCONNECTING MIDI DEVICES
If you disconnect a device in your actual studio, you should also disconnect it in your Studio Setup document. To do so: a
Click both directional arrows to the left of the MIDI device you wish to disconnect.
Click both directional arrows to disconnect a MIDI device
OMS Setup disconnects the MIDI device and moves it to the top of the Studio
Setup document.

This is better than deleting the device because it remains in your
Studio Setup document. Then, if you reconnect the device at a later date, you need only re-connect it in the Studio Setup document, as well.

USING MIDI THRU PORTS
Most MIDI devices have a MIDI Thru port, which passes along any
MIDI data received on the device’s MIDI In port. MIDI Thru ports let you “daisy-chain” MIDI devices. In a Studio Setup document, you represent Thru port connections by connecting one MIDI device to another.

USING MIDI MERGERS
A MIDI merger combines the MIDI outputs of two different MIDI devices into a single MIDI output.
For example, assume your studio has a standard MIDI interface and that you have two MIDI keyboard synthesizers. Without a MIDI merger, you could connect only one of your keyboard’s MIDI outputs to your computer.
To Mac
Figure 26: M1 cannot be used as a MIDI Controller
This results in the following Studio Setup document:

By using a MIDI merger, you could combine the outputs of both keyboards, so that either could be used as a MIDI controller.
To Mac
Figure 27: Connecting a MIDI Merger
To indicate the use of an external MIDI merger in the Studio Setup document, simply connect the MIDI outputs from both merged
devices to the MIDI interface as shown in Figure 28
.

USING MIDI PATCHBAYS
A MIDI patchbay (sometimes called a patcher, switcher, or thru box) is an external box that contains numerous MIDI In/Out jacks, which allows you to connect many MIDI devices to a single MIDI interface.

MIDI Port Numericals
Figure 33: Studio Setup with Multiport MIDI Interface
Make sure you set the MIDI Port numericals to mirror the physical ports used on your MIDI interface. For example, if your M1 is connected to Port 5 on the Studio 4, set the M1’s MIDI Port numerical to
“5” in the Studio Setup document.
If you use a programmable multiport MIDI interface, it’s important to program a “do nothing” patch into its internal memory. MIDI sequencers perform their own MIDI routing and thru operations, so your multiport interface needs a program that does NO internal
MIDI routing of its own—this is called the “do nothing” patch.
For example, if you use Opcode’s Studio Patches program (which comes with Opcode’s multiport MIDI interfaces), your “do nothing” patch would contained no modules (as shown in
Figure 34: “Do Nothing” Sequencing Patch
For more information about Studio Patches, see your Studio Patches manual. For more information about programming other MIDI interfaces, see their manuals.

Decide whether or not you want to use the Rock Drum Kit.
If the option is checked, your sequences play back using a drum kit equivalent to
General MIDI Drum Patch #9. If the option is unchecked, your sequences play back using a drum kit equivalent to General MIDI Drum Patch #1 (standard kit).

To test MIDI data flow from MIDI devices into the Mac, each device must be able to generate MIDI data. On controller instruments just strike a key, pluck a string or hit a pad. When the Mac receives the
MIDI data, the line connecting the two devices blinks and a voice that says “MIDI received” emanates from your Macintosh.
?
NOTE: If your Studio Setup contains MIDI merging (multiple sources into one port), the wrong arrow may flash when testing MIDI connections from devices connected to the merger. When MIDI arrives from a merged source, only one of them is going to flash, and it won’t necessarily be the one that really sent the data.
For devices that have no keyboard, the best way to test MIDI data flow to the Mac is to initiate a bulk dump from that MIDI device.
