Am I the only one with the reverse SYNC/TAP and PING PONG button colors?
Yes, you are.
I heard the legend of the reversed-button Matriarch, but I just assumed it was a fairy tale.
The value of that unit is incalculable!
(Keep your studio doors locked.)
Would you consider trading it for my Upside Down Stamp?
Are you kidding me, it’s a stamp on aerial acrobatics, I prefer to keep my Matriarch… 
If this were me, I would consider it only if the buttons were upside down.
Sounds like a warranty issue - check if the delay goes “pong ping”
I wish this forum had “thumbs up” ratings,
'cause there are some greats replies here.
