One of the last unfulfilled capabilities of the Aeros is Bluetooth support … “for reasons”.
Would be simply amazing if the Bluetooth could pair with the audio in of the Kemper Player … which has no aux in or effects loop, but has Bluetooth.
Latency won’t be an issue if you don’t route the input signal to the output (only the recording playback) and monitor the live sound direct. Not an issue if the playback sound is laggy by 30ms or more. I’d also send the BB into Aeros Aux in and send that out Bluetooth as well. That should keep it all nicely in sync.
