<h2> <a name="C8"> 8. MIDI Control</a></h2></P>
XTONE Pro has 6 smart foot switches and 1 expression pedal interface for playing control. When you press them, Pro sends MIDI CC commands out via the USB and MIDI OUT interface. When a valid MIDI command is received on the MIDI IN interface, Pro will also forward it to the USB and MIDI OUT interface in real time.
The expression pedal recommended ZOOM FP02M.
Please refer to the support document of the expression pedal manufacturer you purchased to ensure that the polarity of your expression pedal is consistent with XTONE / XTONE Pro. Mismatched polarity may result in damage to the XTONE / XTONE Pro. More infomations about expression pedal please check FAQ.
Nowadays, software effects have very powerful MIDI control systems. With Pro’s foot switches and expression pedal, you can do whatever control you want. For details, read the MIDI specification chapter below.
#### MIDI Command Group
XTONE Pro has three MIDI command groups, each group corresponds to 7 different value of MIDI CC commands.
Long press A, B, C foot switch can be switched to the corresponding group, different groups show different LED colors:
<div><center><p style="color:green;">A group - green</p><p style="color:blue;"> B group - blue</p><p style="color:red;"> C group - red</p></center></div>Different MIDI command groups, 6 foot switches + 1 expression pedal can send 7 different MIDI commands, which means XTONE Pro can send 3 x 7 = 21 different MIDI commands, control 21 different parameters in the software.
The following lists the MIDI CC values corresponding to the foot switch and expression pedal in the three MIDI command groups.
<div><center></center></div>
#### MIDI Command Mode
XTONE Pro has 3 MIDI command modes, <div><center><p style="color:green;">Press A+B switch to Mode 1</p><p style="color:blue;"> Press A+C switch to Mode 2</p><p style="color:red;"> Press B+C switch to Mode 3</p></center></div>When the switch is successful,** Mode 1 blinking green, Mode 2 blinking blue, Mode 3 blinking red.

#### Expression pedal
Polarity of the EXP IN of XTONE/XTONE Pro
Tip: Input
Ring: Output
Sleeve: Ground
<div><center> </center></div>
XTONE/XTONE Pro needs to use RTS expression pedal. Please refer to http://expressionpedals.com/list-of-expression-pedals to ensure that the polarity of your expression pedal is consistent with XTONE / XTONE Pro. Mismatched polarity may result in damage to the XTONE / XTONE Pro.
We recommend ZOOM FP02M as the expression pedal of XTONE/XTONE Pro. Also,the expression pedal with polarity switch such as Nektar NX-P works, too.
If you can't confirm the polarity of the expression pedal,you can try:
1. If when you pulg in the expresiion pedal,the XTONE will shut down, it means the polarity does not match or you are not use TRS cable.
2. Please MIDI map a wah or volume parameter in the effects app you use, and then step on the expression pedal from the beginning to the end at a constant speed, and determine whether the range of the parameter matches and whether the control is linear. If not, it means the polarity does not match.
