I have retired my Sony Vaio laptop that I used to "drive" our Disklavier piano. I have a new iBook G4 and have downloaded MetroSE
On the pc I used Calkwalk Home Studio 9.0 to edit downloaded midi files to:
1. Edit the piano track assigning it to channel 1 which would "drive" the keyboard.
2. Adjust the overall volume (velocity)
3. Output the file to a midiman minisport 1x1 usb midi adapter, which connected to the piano.
4. Provide a playlist
I have been able to change the channel assigment, adjust the velocity,
but I do not understand how to output the midi to the port 1.
thanks
