Oriental Music on PA900: How to link ?

Hi! I’m a beginner in MAO and DAW.
Please I would like to know how to link a PA900 arranger to the computer and record some oriental music on cubase.
Oriental Music requires sometimes the use of quarter tones, so It’s impossible, as far as I know, to use midi connections.
The result which I’m looking for is:
Recording the style which I’m playing
Recording the sounds which I’m playing
Respecting the quarter tones
Some how, It’s like the result we obtain by recording an MP3 version of the song, but, divided into tracks
What Hardware do I need ? And how to link ?
Thank you for your help :slight_smile:
