Installing OMS or FreeMIDI (Classic Mac OS only)

A typical MIDI studio is complicated, with multiple MIDI devices attached to one or more MIDI interfaces – for example, a sound module and

MIDI keyboard connected to a MIDI interface plugged into the printer, modem or USB ports on your computer.

If you install FreeMIDI or the Open Music System (OMS) then this is made simple: your music programs show a list of the devices (e.g. in

Sibelius’s Play Z Devices dialog) and the sounds they can play (in Sibelius’s Play Z Mixer dialog).

Please note that both FreeMIDI and OMS are licensed from other companies, and as such are not a part of Sibelius. For more information:

• FreeMIDI – licensed from Mark of the Unicorn, Inc. (www.motu.com)

• OMS – licensed from Opcode Systems, Inc. (www.opcode.com)

Deciding what to install

• If you don’t have any external MIDI devices, you don’t need to install OMS or FreeMIDI. Sibelius can play reasonable quality sounds

through your Mac’s speakers instead using QuickTime –  Setting up QuickTime Music below.

• If your MIDI devices are connected to an OMS-compatible MIDI interface,  Setting up OMS below.

• If your MIDI devices are connected to a FreeMIDI-compatible MIDI interface,  Setting up FreeMIDI below.

• If you are using FreeMIDI-compatible programs and OMS-compatible programs simultaneously,  Setting up FreeMIDI in

OMS compatibility mode below.

• If you are using FreeMIDI-compatible programs and OMS-compatible programs but never simultaneously,  Setting up

FreeMIDI and OMS separately below.

Setting up QuickTime Music

If you do not have any external devices, Sibelius will use QuickTime Music to play back your scores. QuickTime Music is a built-in extension of

the Mac operating system that synthesizes sound through your Mac speakers, using the Roland Sound Canvas General MIDI sound set. It

should be installed by default, but if it isn’t listed as a device under the Devices dialog in Sibelius, re-enable it from the Extensions

Manager (under Control Panels in the Apple menu).

If you don’t have QuickTime or need to update your copy (Sibelius requires version 4 or later), go to www.apple.com/quicktime to

download an update.

Compatible MIDI interfaces

MIDI interfaces that support FreeMIDI include: MOTU 1296, MOTU 24i, MOTU 308, MOTU 1224, MOTU 2408, MTP AV USB, MIDI Express XT

USB, Micro Express USB, FastLane USB.

MIDI interfaces that only support OMS include: Roland Super MPU64, Roland UM series, and MIDIMan MIDISport 2x2 USB.

Using OMS and FreeMIDI in Sibelius

• OMS and FreeMIDI recommend you switch off virtual memory when using them – choose the Memory Control Panel from the

Apple menu to toggle this. To make sure, Sibelius refuses to use FreeMIDI if virtual memory is switched on.

• If you have both OMS and FreeMIDI installed, Sibelius assumes by default that you want to use FreeMIDI (because you can always use

FreeMIDI compatibility mode to use OMS from FreeMIDI).

• When using OMS or FreeMIDI a submenu called OMS or FreeMIDI appears in the Play menu. The OMS menu contains options

MIDI Setup, Studio Setup and Panic. The FreeMIDI menu contains Interface Settings, Edit Configuration and Panic.

Panic silences all the sounds, similar to Play Z All Notes Off. The other menu options take you to setup features in OMS and

FreeMIDI that are also available in those programs directly. Note that when using FreeMIDI in OMS compatibility mode, the FreeMIDI

options are shown.

Setting up OMS

• Install OMS by double-clicking on the Install OMS icon and following the on-screen instructions

• Connect your OMS-compatible MIDI interface to the serial or USB port of your Mac and install any necessary drivers (refer to the

documentation that came with your MIDI interface for details). Ensure that any MIDI/Thru switches are in the MIDI position, and that all

MIDI devices are switched on.

• Locate and open the OMS Setup program

• The Create a New Studio Setup dialog appears. Click OK.
