I only play in a live band so an arranger doesn't get a lot of use. Though I do use a Yamaha PSR-550 for working out band parts but mostly not in arranger mode. Synth Zone has always provided forums for all brands of keyboard for close on 20 years but that has never meant that I owned all the keyboards I have forums for.

I am thinking my next stage keyboard is most likely to be a Korg Kronos. I like all sorts of music from jazz to rock but I currently play in a rock cover band. Not all rock is 3-chord harmony. One of my favorite bands to hear live is Steely Dan, and their material is anything but 3-chord harmony. On the other hand 3-chord harmony works fine for the right song and arrangement. Sometimes 'simple' can be powerful and elegant in the right hands.
