Played a few times. Not recommended IMHO.. No where near Havian ( Pa300 with better 88 keys). Down grade from Havian.



Xe20 is ek50 with Korg b1 keys ( entry level $499 digital piano) with additional piano sounds ( german/ Italian).
Arranger polyphony is still 64 and almost none editing abilities except for set list. Havian was full pa300 touch screen with better editing/ song book, etc.

The only selling point for xe20 is portable/ plays SMF/ Wav and Mp3 without loading from USB drive and L/ R outputs. Zero to none (even though they are now adding) ( pa80 / 50/ microarranger generation) style support. Remember, the styles were busier ( mainly due to over complex fills and bass lines sometimes that you can’t just mute Acc tracks). Korg styles got better after Pa3x/Pa900/600 generation. This was 2 generation before ( before PA1x generation).
DGX 670 is miles ahead but heavier. Will load psr styles, have mic input with efx, etc. has blue tooth but no stereo outs and doesn’t play Mp3. ( will play Wav and SMF). I believe user style creation feature and Bluetooth audio is there as well.

Both lacks physical midi in/outs so can’t use as 88 key controller unless you are hooking up with computer or converter box which will cost you 80/100$.

Since you already have Havian, the only good this is to use as song player (smf/Wav/mp3) and use is as live. Havian it light 33Ibs, but xe 20 is lighter, 25lbs. No joy stick like Havian either.
