Apple AirPods don’t work with Cubasis/Ravenscroft 275 ios

[plaufr1624]

Hi,
I have an iPad, cubasis 2, Ravenscroft 275 for iOS. Apple Bluetooth air pods work fine with Cubasis stock piano sounds. But not with Ravenscroft.
When I put in air pods message says audio converted to 41 kHz.

There are frequency options under cubasis 2 and Ravenscroft. I don’t see any control options for air pod frequency.

I’ve messed with this for a while, no luck. I can use wired headphones with cubasis 2 and Ravenscroft no problem. But once I use the AirPods (or my Sony Bluetooth speaker system for that matter) Ravenscroft won’t work.

Any suggestions? Thx!
