Casio MIDI Driver??

With the Casio Privia PX-120, which has MIDI ports and earphone jacks (but no line outs or USB):

(1) Could the earphone jacks send the Casio music signal into the Mac and GB for recording?

(2) What cables and/or adapter would be needed?

(3) With that hookup, could the Mac's earphone jack be used to listen to the Casio while being played?

Thank you.

yes

What cables and/or adapter would be needed?

whatever type of jack the keyboard has to a 1/8" stereo plug

With that hookup, could the Mac's earphone jack be used to listen to the Casio while being played?

yes

Thanks so much for the Casio PX-120/Mac answers. Very helpful.

I have another question which may not belong in this forum but I can't see where else it would go.

Recording the sound signal from the Casio PX-120 into the Mac, what kind of file size would be generated? I realize this may vary with sample rate and/or other factors, but let's say a half-hour or hour of continuous music. Is there a way to predict this?

I would probably save directly to external HD, and then at times burn to CD.

Thank you.

try this driver:

otherwise you need a MIDI interface:

And if you want to record the sounds of the Casio - which may be better than the GB sounds - you can connect it to GB as a Real Instrument from the line-out of the keyboard.
