That's very true. And as you say in many ways they are probably better in many ways for pulling up complex setups quickly in a live situation.

There is only one downside to using an arranger. On most arrangers there doesn't seem to be a way to completely lock out the arranger accompaniment features. On a few occasions I have heard an arranger backing suddenly start up in a band due to a mistaken button press. It is a total train wreck on the rare occasions that happens. It would be just nice if there was a way to lock it off/on from a menu only.
