Actually, the Ketron cannot substitute kicks and snares etc, or change electrics to acoustic basses or guitars. That’s the nature of audio loops.

You get more realism if the loop is PERFECT for what you need, but it comes at the cost of being unchangeable (and quite honestly, pretty easy to pick out if used in a different style) and you still have the issue of only having a few correctly voiced chord types.

If you are the type that never touches the stock ROM styles, and don’t play enough songs that style repetition becomes apparent, loop arrangers are great. But if you like to fiddle a little with your sound, if you want to use a style twice or more, but want it to sound different for each song, loops quickly become tiring, imho…

Personally, I want to see comparison videos demonstrating what each arranger does that the others CAN’T do! I’d like to see Korg’s running two styles simultaneously. I’d like to hear Yamaha demos that use the Ensemble revoicing to get correct horn voicing. I’d like to hear clip launching on Ketron’s. I’d like to see videos showing which arranger can edit a rock style into an acoustic style the easiest.

It’s this kind of stuff that still juices me about arrangers, not seeing how close someone can get a bunch of different arrangers to sound playing a hokey old tune…. Progress is being able to do something NEW, not the same tired old stuff. Compare THAT! 🎹😎
