I have exactly one piece for multiple pianos, and it's for two pianos eight hands. Eighters Gonna Eight was started in February, 2017, backburnered, returned to in July, 2018, and finished in August, 2018. It's a project originated by Sarah Bob to play with Marilyn Nonken, Donald Berman, and Geoffrey Burleson. It was finished a day before this post, so what I have is crappy MIDI.
There are four movements, taking 21 minutes to play. The MIDI of three of the movements is embedded below.
The first movement is slow to develop, and is originally about hocketed E's passed between the pianos, and the upbeat figures that slowly develop to become the main material.
The second movement is about fast swing eighths and is jazzy.

The third movement is a slow movement, and slow piano music in MIDI sounds about as bad as anything in MIDI sounds, so I haven't included it here.
The fourth movement begins with dorky middle register stabby stuff that resonates on the low strings of the piano, which the secondo players depress silently -- the resonances are not in the MIDI. The stabby stuff eventually acquires a low bass partner that becomes a bass line somewhere between walking bass and funk; at times there are stabby parallel fifths in the bass as well, in tribute to John Mackey. The hocked unisons return as a third element, and at the ending, the resonances return. Bye.
