<p><h2><a name="C12"> 12. Device Command</a></h2></p>
<p>The Device command is a special message type inside AIRSTEP. It is an internal command used to switch the local preset of AIRSTEP. Therefore, when Device is selected in the message type, the output interface will not be displayed. You can use the Device command to switch to the next or previous preset position, or jump to any of the five local preset positions. The setting method is as follows:</p>
<ol>
<li>Select "Device" in the Message Type

<li>Then select the method you want to switch in Preset Action. Then go back to the main page and click the save button in the upper right corner.
<div><center><img src="https://www.showdoc.cc/server/api/common/visitfile/sign/fab0eee966c60da8c3adafbe4e2da7b1?showdoc=.jpg" alt="" /></center></div>
<strong>Important:</strong> Unlike the preset switching function of the multi-function button, the Device command is not a global message, so it is only valid within the preset that been defined.</li>

<p><h2><a name="C13"> 13. Footswitch Settings</a></h2></p>
<p><div><center><img src="https://www.showdoc.cc/server/api/attachment/visitfile/sign/b2acccf108f2c39a2e53956a3ced97f4?showdoc=.jpg" alt="" /></center></div></p>
<p>AIRSTEP's footswitches can be set to three trigger modes: press, release, and long press. Each footswitch can send up to 8 different messages, and each message can correspond to a trigger mode.</p>
<p><div><center><img src="https://www.showdoc.cc/server/api/attachment/visitfile/sign/e9c87691b075a1e03fe48e7ba198e1ae?showdoc=.jpg" alt="" /></center></div></p>
<p>Footswitches can be set to two modes: normal and toggle. In the normal mode, the same message or messages will be sent via the same trigger action by the footswitch. In toggle mode, two different message or different groups of messages will be sent for the first trigger and second trigger of the same footswitch action , which greatly increases the flexibility of control.</p>
<p><div><center><img src="https://www.showdoc.cc/server/api/attachment/visitfile/sign/da4224aef7e70db91d2d1a4f06af48ee?showdoc=.jpg" alt="" /></center></div></p>
<p>The footswitch indicator also has three LED modes: Normal,toggle, and Off.
When AIRSTEP is connected to the AIRSTEP Lite( Lite works as wireless external footswitches), the number of footswitches on the system increases to 10. In wireless external mode, AIRSTEP Lite’s footswitches has the same function as AIRSTEP. Press the footswitches on Lite and all messages will be output from AIRSTEP.</p>
<h6>Guideline of the settings in Normal Mode of footswitches</h6>
<p>When the Toggle mode button is turned off, it means the normal mode. In normal mode, the trigger mode is set in each message. If you only need to send one message, you only need to select your trigger action in the “Trigger”. If you need to send multiple commands by one trigger action, you can add more messages and set them to the same trigger mode or different trigger modes.</p>
<p>Example 1: One press to send multiple messages:</p>
<p><div><center><img src="https://www.showdoc.cc/server/api/attachment/visitfile/sign/e8e624a105ef9cf46050dd9bf06f62a8?showdoc=.jpg" alt="" /></center></div></p>
<p>Example 2: Press/release to send different messages:</p>
<p><div><center><img src="https://www.showdoc.cc/server/api/attachment/visitfile/sign/a590c88cd7824c72b21a19b713972fe4?showdoc=.jpg" alt="" /></center></div></p>
<p>Example 3: Release/long press to send different messages:</p>
<p><div><center><img src="https://www.showdoc.cc/server/api/attachment/visitfile/sign/88a36470ebb485aa4646d963426f8e38?showdoc=.jpg" alt="" /></center></div></p>
<p>> Note: Press and long press are conflicting trigger modes, because long press will definitely trigger the press action, so they cannot be used together.</p>
<h6>Guideline of the settings in Toggle Mode of footswitches</h6>
<p>When the toggle mode button is on, it means toggle mode is enabled. Toggle mode is to send different messages with twice trigger of one same action(e.g press two times). The message or messages sent each time can be defined in Toggle On and Toggle OFF respectively. Toggle On is the first time you stepped on it, when Toggle Off is the second time. Up to four messages can be defined in Toggle On or Toggle Off respectively.</p>
<p><div><center><img src="https://www.showdoc.cc/server/api/attachment/visitfile/sign/02b5daf3982c1fc6f6caf3cab7207960?showdoc=.jpg" alt="" /></center></div></p>
<h6>Guideline of settings of footswitch indicator mode</h6>
<p>In the LED Display Mode column, you can set three modes: Normal, Toggle, Off.</p>
<p><div><center><img src="https://www.showdoc.cc/server/api/attachment/visitfile/sign/da4224aef7e70db91d2d1a4f06af48ee?showdoc=.jpg" alt="" /></center></div></p>
<p><strong>Normal Mode of the Footswitch Indicator:</strong> Among all the footswitch indicators set to the normal mode in a preset, which footswitch is stepped on, which light is always on.</p>
<p><strong>Toggle Mode of the Footswitch Indicator:</strong> When the Toggle mode of the footswitch is turned on, the Toggle mode of the footswitch indicator will also be automatically turned on, so that the status of the Toggle Mode of the footswitch can be correctly indicated. When the footswitch is in Toggle On, the corresponding indicator is on, and when the footswitch is in Toggle Off, the corresponding indicator is off.</p>
<p>At the same time, the Toggle mode of the footswitch indicator is not just limited to be used as an indication of the toggle mode of the footswitch. Any two successive trigger actions can respectively correspond to the on and off of the footswitch indicator. For example, in the normal mode of footswitch, if a single footswitch has only one trigger action, it will light up the first time it is triggered, and it will turn off the second time it is triggered. If a single footswitch has two trigger actions, such as press/release, then it will correspond to different indicator status, for example, press action and release action, one action the indicator is on and the other action the indicator is off.</p>
<p><h2><a name="C14"> 14. MIDI Forward</a></h2></p>
<p><div><center><img src="https://www.showdoc.cc/server/api/attachment/visitfile/sign/8fe51fbf2daf5363605712b1dfc1910c?showdoc=.jpg" alt="" /></center></div></p>
<p>AIRSTEP's traditional MIDI input interface, USB, Bluetooth can receive MIDI messages. All received MIDI messages can be routed and forwarded to any output interface, including 5-Pin MIDI OUT interfaces, USB, Bluetooth.</p>
<p>For example, messages through a traditional MIDI input interface can be forwarded to the USB output, MIDI messages input through the USB can be forwarded to the Bluetooth output, and MIDI messages input through the Bluetooth can be forwarded to the 5-Pin MIDI OUT interface.</p>
<p>You can connect an USB MIDI keyboard to the USB interface of AIRSTEP and turn it into a Bluetooth MIDI keyboard benefits from the MIDI forward function.</p>
<p><div><center><img src="https://www.showdoc.cc/server/api/attachment/visitfile/sign/15c38d5cf7afa179105b03d9eeaf1037?showdoc=.jpg" alt="" /></center></div></p>
<p>> Note: Message 1 in the picture example on this page is for MIDI trigger. If you only use the MIDI forward function, you don’t need to set it. If you want to know about the MIDI trigger function, please read next section.</p>
<p><h2><a name="C15"> 15. MIDI Trigger</a></h2></p>
<p><div><center><img src="https://www.showdoc.cc/server/api/attachment/visitfile/sign/c05f00d9c7e909516aa8b3c7b37309de?showdoc=.jpg" alt="" /></center></div></p>
<p>AIRSTEP's 5-Pin MIDI input interface, USB, Bluetooth can receive MIDI message input. AIRSTEP can use a specific MIDI message from any MIDI IN as a "trigger message". After detecting the "trigger message" input, AIRSTEP can immediately output MIDI messages, HID messages or Relay messages, or trigger the Device Command, and up to 8 messages can be sent by MIDI Trigger, to achieve the same function AIRSTEP’s footswitches.</p>
<p>For example, you can connect a traditional MIDI foot controller to AIRSTEP as an extended pedal. When AIRSTEP detects a specific MIDI "trigger message" input from the controller, it could immediately send a custom HID message to control the Play/Pause of the player on the computer. It is a result of setting the MIDI Trigger to send HID messages. Therefore, the MIDI Trigger function turns the traditional MIDI foot controller into a Bluetooth computer keyboard.</p>
<p><div><center><img src="https://www.showdoc.cc/server/api/attachment/visitfile/sign/2e44e532377a034f435f2759e6e61700?showdoc=.jpg" alt="" /></center></div></p>
<p>The parameter with Trigger is the trigger message setting. Trigger Type is the message type for trigger message. You can select MIDI PC or MIDI CC for triggering. After setting the trigger PC or CC comMand, the MIDI IN of AIRSTEP can send the specific message or messages after receiving this specific trigger message. Below the trigger message settings are the messages sent settings after triggered. For details, see: <a href="#C2">Message types sent by AIRSTEP</a>，<a href="#C11"> Edit messages</a>，and <a href="#C12">Device command</a>。</p>
<p><h2><a name="C16"> 16. Expression Pedal Inputs</a></h2></p>
<p>After AIRSTEP is connected to the expression pedal, it can send MIDI messages through the 5-Pin MIDI output interface, USB, Bluetooth, and up to 8 different MIDI messages can be sent by one expression pedal. AIRSTEP is compatible with all types of expression pedals, whether it is TRS or RTS type, you can use it. Use the TRS cable to connect AIRSTEP to the expression pedal.</p>
<p><strong>Line sequence selection:</strong> Click EXP on the main page. The expression pedal input 1 (EXP 1) is taken as an example in the figure. The expression pedal line sequence is shown at RTS.</p>
<p><div><center><img src="https://www.showdoc.cc/server/api/attachment/visitfile/sign/c2b119017bb3f1366d42716fdfffb1c1?showdoc=.jpg" alt="" /></center></div></p>
<p>If your expression pedal is of RTS type, please select RTS, if your expression pedal is of TRS type, please select TRS. Click on the link to check your expression pedal type: [<a href="http://expressionpedals.com/list-of-expression-pedals](http://expressionpedals.com/list-of-expression-pedals">http://expressionpedals.com/list-of-expression-pedals](http://expressionpedals.com/list-of-expression-pedals</a> "<a href="http://expressionpedals.com/list-of-expression-pedals"">http://expressionpedals.com/list-of-expression-pedals"</a>;)</p>
<p>If you are still not sure, please connect your expression pedal, and then click TEST, after the interface appears as figure. Depress and lift the pedal at a constant speed throughout the entire range of the expression pedal. If the progress bar moves at a constant speed with the expression pedal’s moving, the value will also change uniformly within the range of 0-127, indicating that the line sequence is correct. If not, please switch to another wire sequence type.</p>
<p><strong>Expression pedal output:</strong> You can choose to send MIDI CCs to any output interface. The setting method is the same as all the messages above, see: <a href="#C11">Setting Message</a>.</p>
