I almost lost a big client yesterday when over the talkback being a latch switch instead of momentary switch. There has got to be a workaround for this issue but I’ve searched all the forums here with no success. I did have an older Tascam US2400 that had a dedicated input for such a device but sold it and was forced to use a sustain input on a keyboard to trigger the TB. I’m using a momentary switch but it still latched the TB button. Please help me out here and thank you in advance!
