Grand Staff Piano all on one clef

Apr 6, 2019

I used to have software where I just played my usb/midi keyboard, set a quantize level, and it recorded basic music (for beginner students) it quite well.  It would generally separate the treble and bass clef just fine.  I could select and move notes as needed after with my mouse.   

Everywhere I search online and here it talks about separating vocal or band parts, but no discussion on basic piano being split between the two staffs at middle C and tweaking it from there.  It all records on only one clef at a time.  How can I adjust this?  Thanks so much.
