Reducing the Amount of Control

Change Data Transmitted

(RECEIVE CONTROL CHANGE DATA THIN)

Receive Control Change Data Thin Function

When the GI-20’s transmission mode is set to “MONO” (p. 14), the Control Change messages received at MIDI IN are increased due to the output from all of the six strings. If a large number of Control Change messages are being received at the same time, it may cause data processing to stop, with the error message (p. 37) being displayed as a result. If this occurs, you can use the Receive Control Change Data Thin function to thin out some of the Control Change messages received at MIDI IN, while giving higher priority to the most recently received messages.

*With the factory settings, Receive Control Change Data Thin is set to “On.”

1.Turn off the power to the GI-20.

2.Hold down [WRITE] and turn on the power.

3.Press [SELECT], causing the first three indicators on the left of the display to light up.

4.Press [PATCH/VALUE] to select “On.”

If you do not want to reduce the amount of data received, set this to “of” (Off).

5.Turn the power off.

Limiting the Extent of the Bend Range (BEND RANGE MAX)

Although the GI-20 has a maximum bend range setting of 24, unless the GI-20 and your sound module feature the same bend range settings, you may find that functions such as pitch bend and string bending do not work well.

However, some sound modules have only a narrow range of settings you can make. In such situations, use BEND RANGE MAX.

BEND RANGE MAX helps keep poor operation to a minimum by limiting the GI-20’s bend range to that of the connected sound module.

For example, setting BEND RANGE MAX to 12 limits the maximum value for the BEND RANGE output by the GI-20 to 12.

*For more on your sound module’s specifications, refer to the owner's manual that came with it.

*With the factory settings, this is set to “24.”

*When BEND RANGE MAX is set to “12,” the sound module is retriggered if the pitch is changed by an octave with pitch bend or glide.

Take note of this when Glide or Pitch Bend is assigned (p. 19) to the foot switch or expression pedal.

1.Turn off the power to the GI-20.

2.Hold down [WRITE] and turn on the power.

3.Press [SELECT], causing the first four indicators on the left of the display to light up.

4.Press [PATCH/VALUE] to select “12” or “24.”

If you do not want to limit the bend range, set this to “24.”

5.Turn the power off.
