Global P1: MIDI 1–1: MIDI
651
The MIDI CC# (control change) messages are 
transmitted on the MIDI channel specified in the 
Global P1– External 1 and External 2 pages.
Local Control On [Off, On]
Local Control On (Checked): The OASYS’s internal 
tone generator will be controlled by its own keyboard, 
joystick, SW1 and SW2, and connected foot pedal. If 
you are playing the OASYS by itself, leave this setting 
checked.
Local Control Off (Unchecked): The OASYS’s 
keyboard and joystick etc. will be disconnected from 
the internal tone generator.
This means that operating the OASYS (playing its 
keyboard and using the joystick, or playing back the 
sequencer) will not sound its internal tone generator.
Turn Local Control Off if loop-back from an external 
sequencer causes duplicate notes.
If Local Control is Off, MIDI transmission/ 
reception will occur normally. Playing the keyboard 
will cause the corresponding note data to be 
transmitted, and received note data will play the 
OASYS’s internal sounds.
Local Control and the Control Surface
The Control Surface generates and receives MIDI CCs 
and System Exclusive messages, so that you can record 
knob, switch, and slider movements into a sequencer. 
In order to avoid feedback loops and other strange 
behavior, the Control Surface relies upon an external 
MIDI loop-back when Local Control is turned Off.
In other words:
• If Local Control is On, the physical Control Surface 
will work properly as long as MIDI is not being 
looped back into the OASYS.
• If Local Control is Off, you must loop back MIDI 
into the OASYS in order for the physical Control 
Surface to work properly.
• Regardless of the Local Control setting, you can 
always edit Control Surface parameters via the 
touch-screen.
Knob/Slider Mode: To avoid potential problems when 
Local Control is Off, most knobs and sliders behave as 
if the Knob/Slider Mode was set to Jump. The 
exception is when Control Assign is set to External, in 
which case the Knob/Slider Mode setting is observed.
For more information, see “Knob/Slider Mode” on 
page 645.
Local Control and the Control Surface: more detail
The information under “Local Control and the Control 
Surface,” above, is all that you should need to know in 
most cases. The following information details how the 
system works internally. You’ll notice the results of 
these internal operations only if Local Control is Off
AND there is no MIDI loop-back–which is not a 
recommended configuration.
In this case, you’ll see that the Control Surface works in 
slightly different ways, depending on the Control 
Assign setting.
When Control Assign is set to Timbre/Track or Audio:
• If Local Control is Off, most of the knobs, sliders, 
and switches will only affect the internal sounds 
when MIDI is looped back into OASYS. The 
exception is the Select switches, which always 
control the selection.
When Control Assign is set to External:
• The Control Surface will function properly 
regardless of the Local Control setting.
When Control Assign is set to Real-Time 
Knobs/KARMA:
• If Local Control is Off, the Real-Time Knobs will 
only affect the internal sounds when MIDI is 
looped back into OASYS.
• The KARMA sliders and switches will function 
properly regardless of the Local Control setting.
When Control Assign is set to Tone Adjust:
• If Local Control is Off, the knobs, sliders, and 
switches will only affect the internal sounds when 
MIDI is looped back into OASYS.

Assignable Pedals: When assignable pedals are routed 
to duplicate the function of a knob, they act the same 
as the physical knob.
