AUTO CALIBRATION
The MidiUp has the ability to automatically calibrate to any pot that’s used within the usual range of audio
pots (250K to 1M Ohm). This section decribes the auto calibration procedure.
When used with a guitar pot:
To calibrate the MidiUp to the guitar pot being used, be sure a mono cable is connected to the Audio
Output jack on the MidiUp and that the stereo cable is connected to between the MidiUp and the guitar.
Apply power to the MidiUp after these connections are made. After power is applied rotate the pot on the
guitar to it’s lowest and highest extremes. It does not matter which way the pot is turned first, just so long
as you get to both min and max positions. This completes the calibration.
You can test that the MidiUp is calibrated by rotating the pot a second time to it’s extreme postion and
watching the HI/LO LED on the panel of the MidiUp. The LED should come on when the pot is both near
it’s lowest position and near it’s highest position. There will be a small amount of rotation left over on both
sides of the pot which is normal.
If power is already applied to the MidiUp and you wish to recalibrate without having to remove power then
simply unplug the stereo cord from the guitar and plug it back in again. Rotate the pot as described above
after plugging the cord back in and the MidiUp will again calibrate. BE SURE TO UNPLUG THE CORD
AT THE GUITAR AND NOT AT THE MIDIUP OR CALIBRATION WILL NOT OCCUR. ALSO THE
MONO CORD MUST BE CONNECTED TO THE OUTPUT JACK AS WELL FOR CALIBRATION TO
OCCUR.
When used with a volume control:
To calibrate the MidiUp when used with a volume control, essencially the same procedure is followed as
with a guitar pot. Have everything connected up before applying power to the MidiUp. After power is
applied, move the volume pedal to both of it’s extreme positions. You can then check calibration is
complete by watching the HI/LO LED.
If power is already applied to the MidiUp and you wish to recalibrate without having to remove power then
simply unplug the mono cord from the volume pedal and plug it back in again. Move the pedal to it’s
extremes and the MidiUp will again calibrate. BE SURE TO UNPLUG THE CORD AT THE VOLUME
PEDAL AND NOT AT THE MIDIUP OR CALIBRATION WILL NOT OCCUR. ALSO THERE MUST
BE NO CORD CONNECTED TO THE OUTPUT OF THE MIDIUP FOR CALIBRATION WITH A
VOLUME PEDAL TO OCCUR. When used with a volume pedal a cord is never attached to the output of
the MidiUp since no audio is passes through the MidiUp.
USING THE MIDIUP WITHOUT A FOOT CONTROLLER
If you do not use a foot controller with your MIDI equipment then you must use the default setup in the
MidiUp. The default transmits Control Change 0 over channel 1. Therefore you must set the MIDI unit
that you are controlling with the MidiUp to channel 1 in order for it to respond to the MidiUp. In addition
you need to program the the unit to respond to Control Change number 0. Refer to the manual that came
with the gear for instructions on how to do this.
USING THE MIDIUP WITH A MIDI FOOT CONTROLLER
If you have a MIDI foot controller then you can use it to instruct the MidiUp to transmit other Control
Change Numbers and over other channels. To do this you will need to program your foot controller to
transmit a MIDI Program Change message to the MidiUp.
The channel that the foot controller
transmits over must match the MidiUp channel. The channel in the MidiUp is set by a switch inside
the unit and is factory set to Channel 16
