AxisAndOhs is an external application that replaces the controller (=yokes, joysticks, etc) logic in

• FSX Acceleration, FSX:SteamEdition
• P3D V2 - 3 - 4 - 5
• Microsoft Flight Simulator (2020)

The app supports native Windows USB Game Controller devices, MIDI devices and the Windows voice recognition system. There are additional (free) "Bridge" apps available for more exotic hardware (currently availbale: Elgato StreamDeck, VRI MCP Combo II Boeing, "Knobster")

Key features:

• Assign axis movement and simulator events to joystick axis or MIDI rotary encoders
• Assign any simulator event to joystick or MIDI buttons
• Access simulator internal LVARs
• Utilize the new MSFS HTML variables to control for example the buttons on the G1000 units. 
• RPN scripting: by creating your own scripts, it is possible to trigger more complex functionality with a single button than is normally possible with native simulator events.
• Mouse controlled yoke, rudder, throttle or spoilers axis, with trim (in MSFS too)
• Voice recognition, AxisAndOhs can make use of the Windows Voice Recognition system as an input device for button events or scripts
• TextToSpeech: With RPN scripts you can utilize the Windows TextToSpeech system to make AxisAndOhs read information to you.
• AxisAndOhs will also handle Saitek Multi, Radio, Switch and Backlit Information panels. Up to 3 Saitek Flight Instrument Panels ("FIP") can be used as well.
• The app includes a set of virtual flight instruments that you can drag anywhere on your desktop (for example to another screen) or view them using a web browser on any device (for example phone or tablet) that is connected to your LAN or WiFi.
• API based on standard web technology (XMLHttpRequests and JSONP). It supports sending button events, triggering of simulator event IDs, reading from and writing to simulator variables.

More virtual flight instruments, like the Airbus type PFD, and Bridge programes utilizing the WebAPI are available as separate free downloads on the AxisAndOhs product website.
