Modx is a synth for creative individuals so no easy play backings. (You have to put the work in but you can become an individual that people can recognise)
An arranger is an easy play keyboard where you can press a button and everything is done for you. (You pretty much end up sounding the same as every other arranger player, which means that while people recognise the keyboard the player gets little recognition (Although if you sing it can help)

Bill that is a great assessment that many arranger players don't recognize playing only styles. Yes an arranger kb style play etc,is the easy way out to make music vs the creativeness and originality of using a sequencer and patterns etc..
I'd love to hear the experiences from people that have owned and played both units .. I also never hear whole songs beginning to end on something like the Modx
