\tab This revision of OB-8 software (version B5) has been made to improve the operation of the OB-8 with the DSX, as well as to add some new MIDI features.  For a complete explanation of the OB-8's existing f
eatures, please refer to the OB-8 Owner's Manual and the OB-8 Revision B3 Software Operation Guide.  To verify the software version number of an OB-8, press the PAGE 2 button twice and hold it down the second time it is pressed (the PAGE 2 led should now b
e lit).  Wile holding down the PAGE 2 button, press and hold the SYNC button.  While holding both switches down, the PROGRAMMER leds will display the OB-8's software version number.  If the B led in the GROUP section and the 5 led in the PROGRAM section ar
e now lit, the software version is B5. This version has all of the features of version B3, as well as the following NEW FEATURES:\par 
\par 
\par 
\tab 
1. The Sustain Footswitch on the OB-8 has now been added to the MIDI interface.  This means that when two OB-8s are connected together through MIDI, the Sustain Footswitch on th MASTER OB-8 (the one using MlDI OUT) will also control the Sustain on the SLA
VE OB-8 (the one using MIDI IN).  This feature can also be used by other synthesizers that transmit and recieve Sustain Footswitch information on MIDI.\par 
\par 
\tab 
2. When an OB-8 with MIDI is connected to a DSX Digital Sequencer, the MIDI output of the OB-8 will send out the notes played by the DSX through the MIDI output.  This allows additional synthesizers with MIDI to play the same thing that the OB-8 is playin
g from the DSX.  Now with version B5 (and a DSX with version 3.00 or above), it is possible to have the DSX control the OB-8 AND a synthesizer connected to the OB-8's MIDI OUT INDEPENDENTLY. By assigning the DSX's CV outputs to the OB-8 MIDI (see 
\ldblquote DSX REVISION 3.00 INSTRUCTIONS\rdblquote 
), the DSX will send whatever the DSX's CVs are playing to the OB-8's MIDI OUT without the OB-8 playing it.  The notes that the OB-8 are playing will NOT be sent to the MIDI OUT, so that the two synthesiz
ers can play completely independently.  This also means that when this feature is used, and the DSX is not playing anything on the CVs, no notes will be sent to the OB-8's MIDI OUT regardless of what is being played on the OB-8.\par 
\par 
\tab 3. The overall speed of operation on the OB-8 has been increased to allow the DSX to communicate with the OB-8 faster, resulting in increased accuracy of the timing of notes played by the DSX.\par 
\par 
\tab 4. The range of vibrato lever has been changed for better compatability.\par
