Anyone remember 'home organs'? And how they are now, to all intents and purposes a dead instrument, with only boutique manufacturers producing them at boutique prices...?

This is EXACTLY where arrangers are headed, unless the major manufacturers get off their arses and start to incorporate the sounds, styles and OS features that would allow younger players to not be embarrassed to use one!

I don't hold much hope for the future...

My only hope, right now, is that WS's like the MotifXS leverage their chord following ability and add a more arranger 'on-the-fly' control of the loops and arps. If they only had the 'instant fill to next loop' that arrangers have, I think I would already have one...

But currently, they only have a 'cue the next loop' system, where even loops that ARE fills have to be cued up in advance (not triggered exactly when you need them) and don't automatically lead into a new loop. This simple addition (and loops that stop after one time for Endings) would be the death knell for arrangers, IMO.
