Acme Revival is an independent repair network that operates separately from the manufacturers whose devices we service. Our independence enables a repair model that exists beyond manufacturer-controlled strategies, while preserving the ability to work with manufacturers where appropriate.
AirTurn is a U.S. hardware manufacturer specializing in Bluetooth wireless controllers, hands-free foot pedals/page turners, and portable mounting/stand systems, primarily for musicians and performers using tablets, smartphones, computers, digital sheet music, DAWs, backing tracks, teleprompters, and MIDI applications. Founded in 2008, the company pioneered an early hands-free wireless page-turning solution and has developed multiple generations of customizable Bluetooth pedals and switches that can send keystrokes, MIDI commands, and other app-control inputs. AirTurn is particularly known for its DUO, PED, BT-series and related wireless foot controllers, emphasizing quiet operation, rugged construction, long battery life, and hands-free control. Although music performance remains its core market, AirTurn says its control technology is also used in industrial, scientific, medical, content-creation, and other applications.
AirTurn controller does not appear in the host device's Bluetooth list or repeatedly fails to establish a connection. Stored pairings, incorrect operating modes, or the controller attempting to reconnect to another host are common causes.
One or more footswitches register no input even though the AirTurn controller is powered and connected. This can result from mechanical switch failure, an intermittent ATFS-2 pedal, loose pedal connections, or incorrect switch assignments.
A pedal works inconsistently, requiring repeated or unusually deliberate presses before an input is registered. AirTurn specifically documents intermittent ATFS-2 pedal problems, while worn or compromised switch contacts can produce similar symptoms.
PEDpro membrane pedals may fail to trigger when foot pressure is applied away from the raised activation ridges. Soft footwear, flexible surfaces, or deterioration of the pedal's mechanical response can make missed inputs increasingly frequent.
The controller fails to charge normally, has unusually short operating time, or shuts down despite having recently been charged. Charging-source problems, depleted batteries, battery deterioration, or faults in the charging/power circuitry can produce these symptoms.
The controller does not reliably receive power through its USB charging connection or external power input. A damaged connector, poor cable connection, inadequate USB power source, or internal power-path fault can prevent normal charging and operation.
An AirTurn may initially pair successfully but later disconnect or refuse to reconnect automatically. Corrupted/stale pairing information, competing host devices, firmware issues, or Bluetooth communication faults are common contributors.
The AirTurn shows as connected and may illuminate its status LED when a pedal is pressed, but the application performs no action. Incorrect mode selection, corrupted/customized button mappings, incompatible app configuration, or firmware/configuration problems are typical causes.
The controller behaves incorrectly after mode changes, firmware updates, or configuration changes, including loss of expected pedal functions or inability to communicate with an app. Resetting pairing, restoring the correct operating mode, reconfiguring commands, or updating firmware is frequently required to restore normal operation.
