Disregard the info about using the Yamaha Midi driver unless you are connecting via usb which you are not.You should be using whatever Tascam drivers are ther which most certainly should include an ASIO Tascam driver of some sort. I suspect that your problem is that your Yamaha is not transmiting on the right channel. Lookd at the channels in pref and set your yamaha up to transmit on that channel. Example: Melody is channel 4 I believe so transmit on channel 4. Not knowing which Yamaha keyboard you are using also makes a difference. My Korg workstations have settings for internal and external transmision and I have also found that setting them up in sequence mode is the ticket.
