User guide
• A list of the MIDI interfaces connected to your computer will be displayed. If this list is correct, click OK. If MIDI interfaces that you have
connected to your computer are not detected, refer to FreeMIDI’s troubleshooting information.
• OMS will now attempt to detect devices (keyboards, modules, samplers, etc.) that are connected to your MIDI interface. A list of devices
or MIDI ports will appear. Click on the checkboxes next to each of the devices or ports that you wish to use. Click OK
• You will now be presented with a standard Mac OS Save dialog. Name your configuration, choose a convenient place on your hard
drive and click Save
• Your studio configuration will now be displayed. Check that the on-screen MIDI connections are the same as your studio’s physical
connections. Device information (manufacturer, model, name, properties, receive channel(s) and icon) can be edited by double clicking
on the device / MIDI Interfaces icon. To connect devices, drag them to a MIDI interface, and click once on the in/out arrows
• When you have completed the setup, choose Save from the File menu
• Quit OMS Setup
• Locate and open the FreeMIDI Setup program
• You will be asked whether you wish to use OMS or FreeMIDI. Choose OMS. To change this later you will need to quit Sibelius,
locate and run the FreeMIDI Setup program, open FreeMIDI Preferences (File menu) and switch on Use OMS when
available. Quit FreeMIDI and run Sibelius.
• A dialog will appear informing you that FreeMIDI is in OMS compatibility mode. Click OK to continue. Your OMS Studio Setup will be
displayed. Quit the FreeMIDI Setup program.
• Open Sibelius.
• Set up the Devices dialog as detailed in MIDI devices.
Using FreeMIDI Patch lists in OMS when using FreeMIDI in OMS compatibility mode
If you are using FreeMIDI in OMS compatibility mode, no sound names will be listed in Sibelius’s Play Z Mixer dialog (shortcut M). For the
correct patch names to be displayed, OMS must use FreeMIDI ‘patch lists’ (the equivalent of Sibelius’s sound set files). To do this, Mark of the
Unicorn recommends the following:
• Quit FreeMIDI Setup and OMS Setup
• Locate the Factory Names folder found in the OMS Folder within your System folder
• Open the Factory Names folder, and remove the contents (you may want to back up the contents of this folder, or simply delete
them)
• Open the OMS Preferences folder (in the OMS Folder) and delete the file OMS Name Manager Prefs
• Launch OMS Setup, delete visible OMS Devices, and reconfigure the OMS Setup following the instructions in Setting up OMS
above
• When adding devices in OMS, be sure to choose from the list of Manufacturers and Models. If your device is not listed, assign a similar
device, and modify its name to match your device (e.g. change ‘JV-1080’ to ‘JV-2080’).
• After completing your OMS Setup, choose Save and Make Current from the File menu
• Run FreeMIDI Setup
• Open the FreeMIDI Preferences window (File menu), and choose Use OMS when available from the Software
Compatibility section. You may need to quit and launch FreeMIDI again so FreeMIDI opens using OMS’ setup.
• The same OMS setup above will appear in FreeMIDI. More importantly, the FreeMIDI patch list will remain intact.
• This trick only works when a FreeMIDI program is using the OMS setup. This method does not publish patch lists directly into OMS to
use with software like ProTools, Studio Vision, Cubase and some other OMS compatible software.
Setting up FreeMIDI and OMS separately
• Install FreeMIDI by double-clicking on the Install FreeMIDI icon and following the on-screen instructions
• Install OMS by double-clicking on the Install OMS icon and following the on-screen instructions
• Connect your FreeMIDI- or OMS-compatible MIDI interface to the serial or USB port of your Mac
• Locate and run the OMS Setup program
• The Create a New Studio Setup dialog appears. Click OK.
• Click the checkboxes to select the port (modem and / or printer) to which your MIDI interface is connected. USB MIDI interfaces will be
detected regardless of these settings.
• Click Search. OMS will now search for MIDI interfaces connected to your computer.
