Hopefully at this point, you will hear the Ravenscroft sound through the P125. You should hear the piano sound from the iPad speakers the same as if you tapped the screen keyboard.Ģ) Set the Yamaha as an audio destination in the Device list. So in theory the same should be true for the iPad.ġ) Try to get the P125 to play the Ravenscroft, by going to Settings > Audi/MIDI preferences then selecting it as as Active MIDI Input - not sure how it will be named, but it should be in the list of devices. Connecting the terminal of this instrument and the computer via a USB cable allows you to transmit/receive MIDI and Audio data (USB audio interface) to/from the computer.
