We are in the middle of a session. We have all the tracks we are using armed and ready to record and monitoring off the repro head. Now we can't change the state of any of the tracks.

The transport is still responsive on the remote and the deck. The following switches on the meter bridge still respond.

Meter On
Auto Mute
Auto Input
Delay Inhibit
Master Safe
Rehearse


Channel off/on and NRS off/on flash briefly when pressed.

**Update: I have just reseated all the cards for a second time. It has reset the channels to safe but won't respond to any key presses**
