you wish to run BP2 under OMS, first launch the
utility and make sure that the required output runs fine. When you setup OMS
the external MIDI device(s) must be plugged to the Mac and switched on, so that
OMS will sense them automatically and create the appropriate studio setup
document accordingly. Needless to say, the MIDI interface should also be

Music. Clicking the icon also allows you to set the pitchbend range to 2
semitones, the value used in examples of this document.
a MIDI device (keyboard, synth...) is connected to the MIDI interface attached
to a serial port, the icon of the port ('modem' or 'printer') should be

cmd-T (command-T) to activate "Test studio" and click the icons of QuickTime
Music and other output devices. You should hear chords sent by OMS to these
devices. Playing a MIDI keyboard should similarly produce a visual effect on
the studio document.
there is no communication, select "
in the "Edit" menu to select the proper serial port.
OMS MIDI setup you shoud also check "Run MIDI in background" as BP2 may be used
as a server.
done with all this, save the studio document and quit OMS Setup.
of MIDIshare should make sure that messages are routed via OMS. BP2 does not
recognise MIDIshare and will communicate with it only via OMS.
you try BP2 to use OMS while OMS is not active on your system, you will get an
explicit error message and BP2 will switch to its own built-in driver, which
has limited features.
startup, BP2 reads information about the default OMS input and output stored in
file. This file is supplied by default with the setting of QuickTime Music as
the output, and no input.
BP2.9.3 (68k) or BP2.9.3 (ppc), depending on the type of computer you are
using. In the welcome alert, click "Data", then click the button "Check MIDI"
on the Control panel, and take the option "Check output." A dialog with 16
buttons resembling a calculator is displayed. Click button '1' to play random
music on channel 1.
may not hear anything at all. No panic! Try the following procedures:
BP2 displayed a message telling that it failed to sign in with OMS, you must
install and activate OMS, unless you wish to use the in-built MIDI driver. If
BP2 did not complain about anything, it means that the MIDI interface, the
synthesizer and/or the amplifier are wrongly connected, not powered,
communicating via the wrong MIDI channel, or set to volume zero... Some MIDI
interfaces such as
MIDI Translator II
have input/output lights that keep flashing when data is transmitted. This
the way, don't forget to check the volume pedal on the synthesizer! I have
spent hours finding it...

inactive. Check this in the "Extension Manager" control panel and restart your
OMS is active you won't get any warning at startup and OMS items will become
active (displayed in black) in the "Devices" menu. Select "OMS input-outpu
and pull down the output menu to activate "QuickTime Musi
If you have gone this far it generally works.
OMS is active but you cannot find "QuickTime Musi
in the output list, select "OMS Studio setu
If "QuickTime Music" appears crossed out on the studio document, double-click
it and switch in on.
you expected BP2 to play sounds on an external MIDI device, and OMS is active,
select "OMS input-outpu
and check the name of your MIDI device. If it is not in the list, run "OMS
If you still don't hear it, run "OMS MIDI setu
to select 'modem' or 'printer'. This may require entirely switching off the
MIDI interface, the synth and the Mac, including disconnecting the power supply
from a PowerBook... because the serial port, the interface or the input of the
synthesizer might be stuck.
OMS is not active, you are using the in-built MIDI driver. All you need is to
check either 'modem' or 'printer' in the "Devices" menu, assuming, on certain
Macs, that you run IRTalk or EtherTalk instead of LocalTalk. (See the
"AppleTalk" or "Network" control panel.) Remember, this will not work on some
old PowerBooks such as the PB 150, which cannot communicate with MIDI unless
OMS is installed.
OMS is active and BP2 runs in background, for example you launch it from a
FileMaker Pro database such as "TryAppleEvents.f
you will not hear any sound unless "Run MIDI in backgroun
is checked on the "OMS MIDI setu
panel that is accessible from the "Devices" menu. Since it is an
application-independent setup this option will remain set until you decide to
you have performed changes in the "OMS input-outpu
menus, these may not work immediately. In any case you should store these
changes to the default settings file. Select "
in the "File" menu. BP2 remembers where it found the startup settings file and
will replace it with the updated one. If communication is not working, quit
and restart BP2.
the MIDI output is still dumb... There are bad days like this, notably when a
group of enthusiasts or a person you invited for a candle dinner is sitting
around waiting for a demo! Check cables, power supplies, amplifiers, speakers
and the synthesiser's MIDI set-up until you hear sounds. (Maybe your device is
not receiving on the proper MIDI channel? Check the channel number, set OMNI O
or else, just call your little brother who knows all about such things...)
invite your 'windoze' neighbour over a show until you can manage to make
sounds. Otherwise s/he'll feel like saying something silly, for instance "my
SoundBlaster card works better!"...
