Thanks for the reply, Arlo. I'm really just trying to find someone else who is using or has used the musicIO app with BandHelper / SLM.
I suppose if you take that out of the equation, I'm really just trying to learn how to get BH to route audio to my MacBook Pro or other external device.
I also own a Presonus AudioBox iTwo, and it can do what I need, but it can be kind of flaky in terms of getting a successful connection.
I also own a Griffin StudioConnect which also works, but the jury's still out on that one.
Cheers,
Tony G.
