Midi Sync - Oberheim OB 12 Operating Manual

OB 12
This section of the SYSTEM menu allows you to set the parameters relating to the MIDI Clock for
synchronisation of the Phrase Recorder, the Arpeggio, LFO1 and LFO2 with remote MIDI units.
If, for example, you are using a remote sequencer to control the OB-12 sound generation section
and you are also playing on the instrument's keyboard, by synchronising the Arpeggio or LFO1 or
LFO2 with the sequencer performance time (identified by the MIDI Clock transmitted by the
sequencer itself), you can use an arpeggio tempo and/or LFO1/2 modulation frequency identical
to the sequencer performance tempo.
You can also synchronise the OB-12 Phrase Recorder recording time with the performance time
of a remote sequencer, to ensure perfect recording of the data contained in the sequencer.
N.B.: Some MIDI instruments only transmit MIDI Clock messages during recording and/or playback.
Consult the user manuals of these units to check the exact MIDI Clock transmission mode. Moreover,
if the remote MIDI instrument connected to the OB-12 transmits MIDI Real Time STOP messages
at the end of the playback the synchronisation might not take place correctly.
Other settings in this function concern the MIDI Real Time START, STOP and CONTINUE messages
transmitted and received. The OB-12 is able to transmit these MIDI messages on the basis of the
commands used on the Arpeggio, the Phrase Recorder, the Motion Recorder and the Auto Morph.
This means that you can send these MIDI messages (to start and stop a MIDI sequence recorded
in a sequencer, for example) by activating and deactivating the functions referred to above (by
pressing and releasing a keyboard key for the Arpeggio and Phrase Recorder, and using the
[LOC1] / [LOC2] buttons for the Motion Record and the [AUTO] button for the Auto Morph). You
can also set the section (Motion 1, Motion 2 and Auto Morph) to which incoming MIDI Real Time
messages will be sent.
But we will now see how to set the parameters associated to the MIDI Clock.
From the SYSTEM menu, select option 3-MIDI SYNC; the display will show the following video
page:
containing the following parameters:
STATUS: activates (ON) and/or deactivates (OFF) transmission of the MIDI Clock.
SOURCE: sets the section from which the MIDI Clock is to be generated. This MIDI message
can be linked to the following sections:
LFO1: the MIDI Clock transmitted will be synchronised to the LFO1 RATE parameter.
-
LFO2: the MIDI Clock transmitted will be synchronised to the LFO2 RATE parameter.
-
ARPEGGIO: the MIDI Clock transmitted will be synchronised with the Arpeggio TEMPO
-
parameter.
PHRASE RECORDER: the MIDI Clock transmitted will be synchronised with the Phrase
-
Recorder TEMPO parameter.
MULTIPLIER: sets the multiplication factor of the MIDI Clock in relation to the parameter to
which it is linked. For example, if this parameter is set at 2.0X, the message will be transmitted
228
