AIRTURN BT500S-2 Bluetooth Foot Controller

Thank you for purchasing an AirTurn BT500|S SERIES Bluetooth controller. We hope you enjoy many years of use from it. From page-turning to effects management and presentation control, AirTurn provides a myriad of uses.


The BT500 series works with most Bluetooth 4/5 devices. This includes iPad 3 and later, iPhone 4S and later, and most devices running Android 4.3 or later with Bluetooth 4/5.

Most PCs and Macs equipped with Bluetooth 4.x and HID (keyboard) support are compatible. For older PCs you can use Bluetooth 4.1 and higher USB dongles. The dongle must support HID or MIDI if you plan to connect to MIDI. It is recommended to use a WIDI Master USB adapter for MIDI on a PC/MAC if only MIDI is needed.

A compatible app is required for Android and iOS. Apps are listed on the AirTurn website: For Windows and MacOS, most apps respond to keyboard or macro commands that can be programmed with the AirTurn Manager.

Your AirTurn controller is actually three devices in one box using three different protocols: AirDirect, HID (keyboard & mouse), and MIDI. Since each compatible app may have a different method of connection, you will need to know what MODE to put your AirTurn device in. See the MODES section

for additional information. The default setting is MODE 2 since the vast majority of apps can connect with this MODE, however MODE 1 (AirDirect) is preferable if the App supports it.


The BT500S series and QUAD500 use the same controls for all four models, with 2, 4, or 6 footswitches, or four silent pedals. The Function controls are identical across all four models and consist of a Power button, two LED indicators, and a Mode button. These models also feature a power port, both for extended use and recharging the built-in lithium polymer battery.

The switches or pedals of each model are in numerical order left to right, the function of each switch is explained on page 13.


ON – Press and hold the Power Button for one second until the LEDs flash.
The blue LED will blink about 2 times per second until pairing is started.
OFF – Press and hold the Power Button until the red and blue LEDs turn off.


There are several ways to pair to your AirTurn, depending on the use case.

  • If the app you’re using supports AirDirect, see the next section below.
  • For the standard modes that can cycle through pages and other “keyboard and mouse” functions, skip to Pairing In Mode 2-6.
  • If you’re using a MIDI-enabled app, skip to Pairing in Mode 7.

Once the AirTurn is selected for pairing, the blue LED will blink about 5 times per second until pairing is completed.


Note: This MODE is for AirDirect specific apps only. (AirDirect MODE was created to prevent conflicts with the virtual keyboard). The Bluetooth connection is made with the app. See specific app directions.

  1. Power on the AirTurn
  2. Be sure the AirTurn is in MODE 1 (Hold down the MODE button for 1 blink of the red light)
  3. Turn on your device’s Bluetooth then go to the app you want to use and find the Bluetooth setup screen
  4. Find the AirTurn in the device list and tap on i
  5. If required, tap on the Pair button in the dialog box

iOS ­ Select Settings > Bluetooth and turn on Bluetooth if it is off. When the AirTurn is discovered, tap on the selection. A dialog box will then appear. Tap on Pair.
Android ­ Select Settings > Bluetooth, and turn it on if it is off. Make sure your device is set to discoverable, tap the SCAN button. When the AirTurn appears, tap to pair.

PC ­ Select Control Panel > My Bluetooth Devices > Select “Add a device” > Click next and complete pairing. (Middleware may be required unless you are using a Bluetooth USB Dongle such as the WIDI BUD or WIDI Master or other MIDI over Bluetooth Dongle.)
Mac ­ Select File > New Finder Window > Applications > Utilities > Audio MIDI Setup > Select “Bluetooth” > Next to the AirTurn click “Connect”


MIDI Mode is for sending basic MIDI commands to your app. Support for Bluetooth MIDI is required, and special setup for your tablet or computer may be required. MIDI commands may be set up using the AirTurn Manager. More detailed instructions available online ( or reach out to our support team at [email protected] for further assistance.


AirTurn devices have the ability to pair to your tablet or computer two different ways. We call them Open and Closed pairing. Open pairing is the default method. Use Open pairing when you frequently use different devices with your AirTurn. Used Closed pairing when you are in a band and you always want to rely on pairing with the same device.

AirTurn devices pair in the same way that almost all Bluetooth devices pair. In Open Pairing you do not need to delete the pairing to connect to another device so you can easily pair your AirTurn to your iPad, smartphone or computer. In fact, you can pair up to 8 Bluetooth devices. (In AirDirect, MODE 1, you can pair to an unlimited number of devices).
Bear in mind you can only be connected to one device at a time. If two of your devices have Bluetooth turned on, you must turn off the Bluetooth of the one you do not wish to connect to while you connect to the other device. No pairing reset is required with Open Pairing.
If you connect to more than 8 devices, the next pairing will delete a pairing that you haven’t used recently. If you delete or “forget” the pairing of the AirTurn on a device, restart the Bluetooth and attempt to re-pair with the AirTurn.

This method locks one AirTurn to one tablet, phone or computer.
Use the closed pairing method if you only intend to be connected to one tablet, phone or computer.
Also, use this method if you are in an ensemble with other players using AirTurn devices. It will ensure that you don’t inadvertently connect to each other’s devices. Pairing is required in all MODES.

You can easily switch between Open and Closed pairing methods. With your AirTurn powered off, hold down the MODE button and hold the power button to turn on as usual. Both LEDs will flash to confirm ­ twice for open pairing, three times for closed pairing. You can also change the Pairing method using the AirTurn Manager App, in Advanced settings.


To delete all pairings, or if you would like to connect to another device in Closed Pairing, or you are having connection problems, you can pair again by removing all the existing pairings.
First, delete the pairing from the host device and turn off the Bluetooth. Then, hold the power button on the AirTurn for 8 seconds. The LEDs will turn off, but continue holding until they blink 3 more times. You are now ready to pair again.


The BT500S-6 is also equipped with two 1/4″ analog jacks, allowing the use of expression or CV pedals as analog inputs. These can be used to send MIDI, control a mouse cursor, or directly communicate with compatible apps. Most expression pedals will work without modification; other analog pedals or devices such as joysticks can be used when wired to a 1/4″ plug according to the diagram below:

The following diagram shows how to create a cable to convert a volume pedal to an expression pedal.

The analog ports must be calibrated and programmed via the AirTurn Manager app before use. Be sure to re-calibrate the input when changing analog devices.


Calibration for all analog functions takes place in the AirTurn Manager App. Connect a BT500S-6 and select Analog Calibration, choose a port, and follow the onscreen instructions. You will be instructed to move your expression pedal to its maximum, then back to its minimum. Once calibrated, the analog inputs must be programmed to send a signal (AirDirect, Mouse, or MIDI) in the Analog Configuration panel.


There are seven modes available on your AirTurn. Each mode sends a different signal for each pedal. The AirTurn is set to MODE 2 by default. You can also customize MODES 2-7 with the AirTurn Manager App. (See page 15 for instructions on mode changes)

Switch 1 Switch 2 Switch 3 Switch 4 Switch 5 Switch 6
Mode 1 AirDirect AirDirect AirDirect AirDirect AirDirect AirDirect
Mode 2 Up Arrow Down Arrow Left Arrow Right Arrow Return Space
Mode 3 Page Up Page Down Left Arrow Right Arrow Space Return
Mode 4 Play/ Pause Next Track Volume Down Volume Up Prev Track Stop
Mode 5 Space Enter Home (iPad) KB Toggle Left Arrow Right Arrow
Mode 6 F12 ] 1 X Z Shift + Z
Mode 7 Damper Sostenut o Portamen to Soft Pedal Legato Hold 2
  1. Turn on the AirTurn.
  2. Press and hold the MODE button. The red LED will
    flash once per second from 1 to 7 flashes. The number of flashes corresponds to the MODE number. Be sure to count the flashes.
  3. Release the MODE button following the number of flashes that reflects the desired MODE. The blue and red LED will flash together the number of times indicating which MODE has been set.

Example: To set MODE 2, hold the MODE button for 2 flashes of the red LED, release, and both LEDs will flash 2 times to confirm the MODE 2 setting.
Note: Once the MODE has been set, it will remain the same until it is changed following the above steps.


If you are connected to your iPhone or iPad in MODES 2-6, the AirTurn acts as a keyboard and disables the virtual (on-screen) keyboard. To turn on the virtual (on-screen) keyboard in iOS, put the cursor into a text box and press the Power Button. The Bluetooth LED will turn on to signify that the button was pressed. This feature will only work in MODES 2-6 ­ in other MODES, the AirTurn does not act as a keyboard, so the virtual keyboard will work as normal.


The AirTurn uses an idle timeout function to conserve power. After two hours of inactivity when powered on and connected, the AirTurn will power down automatically. The timer is reset when any button is pressed. You can change this time out period or turn it off completely using the AirTurn Manager app.


To charge the battery, insert the charging cable into the port and plug the other end into any dedicated USB source. For BT500S SERIES/QUAD 500 models you can also use a center negative power supply that is 5-9 V (9V preferred). Charging from a laptop or a computer is not recommended. A charge will last for about 200 hours.
The BT500 series includes several battery safety features to help maintain battery life and health. The battery will stop providing power if it is too low, and stop charging when full. Charging is disabled when the unit is above 45°C, or below 0°C (113°f and 32°f). Charging resumes when the unit is back within operating

To change the configuration of your AirTurn and update its firmware to the latest available, download the AirTurn Manager App from the Apple App Store or Google Play Store. It is available for iPad, iPhone, most Android devices, and Mac computers.

The App allows you to configure the key repeat rate, power-saving settings, select the pairing method, and configure the signals for each of the pedals in each mode. In addition, the analog inputs on the BT500|S-6 may be configured and calibrated.

If any firmware updates are available, you will be notified after the App has connected. After performing the update, the AirTurn device will install it and shut down. Remove the pairing from

your iOS/Android/PC/Mac device, power on the AirTurn, and reconnect. It is recommended to check for updates quarterly.


The unit name in your Bluetooth host consists of several codes to help with support and identifying your specific device. For example:

BT500S-6 v3.0.0 ABCD
V3.0.0 refers to the firmware number.
ABCD refers to the MAC address.
This is helpful if there are many AirTurn units in the same location. Your MAC address will always be the same so you can easily identify your device when you are pairing. You will find your specific MAC address labeled on the bottom of your AirTurn at the end of the serial number.


To reset the AirTurn to factory defaults, hold the first two switches while powering on the device. Both LEDs will flash 3 times and then the AirTurn will power off.
There is also a reset option through the AirTurn Manager.


Wipe down using a damp cloth with a mild detergent or soap-based cleaner to remove dirt and stains from your AirTurn.

  • Do not get the AirTurn wet or place it in direct sunlight for extended periods of time or leave in a hot vehicle.
  • Do not put in trash. Please recycle.
