Is there a way to control the Pandora stations on Onkyo/ Integra Receiver directly from the iPad without going through the on screen tv guide? Like you do with the Sonos driver.
Yes, however, it depends on your model. Per the compatibility chart:

The 2011/2012 Onkyo IP models support direct integration in the Virtual Remote displaying the Pandora stations. Anything before that you’d need to use the monitor connected to your receiver.
