Learn mode
The GpiO BOX is fully user programmable and can be configured to output any
Musical MIDI when any of its 4 input control lines are triggered. To enter Learn
mode position the slide switch to the center when powering up.
Programing
When the GpiO Box is powered up in Learn Mode the Status LED on the
rear of the unit will begin to slowly flash. This indicates that the GpiO box
is in Learn Mode and awaiting further instruction.
Next connect the control button (or other control) you wish to use and
press it. The Status LED with stop flashing amber and go to solid red. This
indicates that the GpiO BOX has detected a button press and is awaiting a
MIDI command.
As a safety feature, if no buttons are pressed the GpiO BOX is left in
learn mode for 60 seconds the unit will exit learn mode and restart
to its most recently selected button mode. This is designed to
reduce the risk of an accidental mode change when mounted in a
rack adversely effecting operation.
Once the LED is solid red a MIDI command can be send in to either of the
MIDI ports on the rear of the GpiO Box. To do this, simply connect the
GpiO Box to the Output of a MIDI device or USB MIDI interface. Once a
command has been received and stored the status LED will return to
slowly flashing. At this point you can either repeat the process with
another button, or set the slide switch to the desired mode (2-Button or
4-Button) and power cycle the GpiO Box.
Once programed the GpiO box will output its new “Learnt” commands in
both Button modes until either reprogramed or reset.
Reset
To reset the GpiO BOX back to its factory default MIDI commands (shown the in
the table bellow) connect a button to line 3, and hold this down while powering
up the unit in learn mode. The status LED will blink rapidly to confirm reset and
the GpiO box will return to its most recently selected button mode
