I have here such an idea
it is about monitor situations with many ways, but it can be also helpful for monitormix from FOH.
situation:
a short feedback sometimes arises somewhere. but even before you can recognise where it could have been, it is away again.
such situations can make you nervous.
my idea:
if there was in the mixingdesk a routine which can recognise of feedback – and points on which monitor-way and on which channel the feedback has begun, this would be a very good solution for the engineer.
remark: no automatic feedback reducer, only one recognition of the origin of the feedback!
I know, this is no simple job!
but it could be a very good sales argument.
