Been a while, Ian. Welcome back.

As I've pointed out when it comes to bends as well as switch activated SA2 actions, if you listen to REAL music played by real musicians, it's amazing how often those performance 'tricks' or idiomatic playing occur EXACTLY at chord boundaries. Bends are used to go across transitions probably at least as much as in the middle of chord sections. They form a way to join up one section with another, or to emphasize the change...

And this is EXACTLY when you can't use them on an arranger! Your LH absolutely HAS to make that chord change, no matter how much you'd like to bend or hit the SA switch. In fact, it's easy to test... Record just the backing. Now play the solo on the top of it. Note how often you play a bend or SA action when the chord is changing.

In fact, if you listen to Martin's fiddle playing later in the first example, when he is making 1/4 note chord changes, he is incapable of using the switch at all... and the performance realism suffers much for it. This is why this stuff is best left to footswitches. You can do them whenever you want to, not whenever your LH can spare the time...

BTW, nice hijack attempt by the Audya camp, but if I'm not mistaken, Audya has no SA/DNC/SN stuff at all, right? LOL
