Hi -

I've got two talkback controls:
- Button on ARC USB
- Additional "client" control, which my clients use at the producer desk, plugged in to 1/4" "Footswitch" plug on ARC USB

If one person activates talkback, and the other presses the button it *cancels* the talkback.
Instead, multiple talkback controls must be additive, such that any press always turns it on while the button is down, and talkback remains on until all buttons are up.

A workaround:   connect two external switches to the footswitch jack.

ADDITIONAL FEATURE REQUEST
"Latching" talkback using short-press
- user presses talkback switch for >.1sec and < 1 sec, talkback latches "on" until pressed again.
- user presses talkback switch for > 1 sec, talkback control is momentary and talkback is turned off when button released.

Thanks!
