How do I save midi external setup for PSR S975

[blackfs]

I love playing the psr s975 but using an external keyboard that has full hammer action piano style keys. In order to do this, each time I switch on, I have to press the function key, midi, edit, and then tab over to the chord detect tab to change the settings for Port1(midi/usb1) for channel 1 to on.

Once I've done that, I can set  Sync start on the PSR S975, and then start playing on the external keyboard, and the PSR will start playing in whatever style I have selected.

Is there any way to save these settings so that they are available next time I turn the PSR S975 on again?

Also, is there a way for me to play the right part sounds from the PSR S975 using the external keyboard? Right now, I hear a piano sound instead of whatever sound is selected.

Thanks,
Fred
