I know this thread is very old but I'd also like to express my displeasure with the inability to use aux switches for +/- in play mode. I believe the issue is more than just a preference but an actual issue when playing live. In play mode, I'm able to tell if the hotswitch settings are engaged because then light turns orange. If I have to settle for being bank mode and using an aux switch to engage the hotswitch function, the hotswitch light doesn't turn orange so I have no way of judging whether I'm in the regular preset settings or the hotswitch settings except trying to guess by the sound I'm hearing. On a noisy stage through monitors that's not always easy but the audience, of course, gets the full mix and can always tell. I should be able to tell what my setting are by quick down at the lights and shouldn't have to guess.
