OyRemote lets you control you network capable Onkyo AV Receiver using the "Integra Serial Communication Protocol for AV Receiver". It has predefined controls to select functions like Input Sources, Volume, Subwoofer and Center levels, Listening Modes etc. You can also define Batch Commands then can then be told to run every time you start the application. An example would be "Select Radio as input, Preset 6, at volume 35 and set Sleep Timer to 30 minutes". To make it easy, the latest version now offers a Command Builder window which contains over 500 commands to build your own command sequence from. You can then use this with your Batch Commands or your user defined custom buttons.
