Casio piano sounds is acceptable but styles are GM quality with 2 variations.

There is none in the market that is light weight 88keys with gigable arranger functionality. Havian was the last that is light weight 88 key arranger. Xe20 as I mentioned is not on the same league.

Light weight portable piano will be Yamaha p121 ( 20 lbs) or Roland fp30x.
None of those has real arranger functions nor have midi in/ outs. Yamaha is 73 kys and light/ Roland has great super natural piano sounds but most complain about escapement key mechanism ( unlike real piano’s)which lags you down for fast licks. With IOS apps both have basic chord following rhythms. Yamaha needs cable and Roland has Bluetooth midi and audio ( meaning you can stream songs from phone). It’s the updated version of fp30.

But none has ease of plug and play XE20’s song play ( Smf/mp3 and wav). Why they are not ideal as playback/ arranger machines. Just portable pianos. They ( p121/fp30x) lack onboard transpose buttons ( need multiple button pressing if you are not hooked to IOS device).


The other option is to get used p85/95/ and go to midi module route, but again , too many cables.
