i was playing a gig--had my Polaris set up, it worked in the sound check fine-- then turned it off--- turned it on before our set was to start and the Polaris  turned on with 90% of the led's on--and no sound , and was unresponsive to all buttons.   i turned it on and off and no change.   so gave up playing it for the set--
packing up after the show i plugged it in again and it seemed to light up normally ,
but i wasnt able to experiment playing it at that time--
now  a day later, i set it up again --turned it on and have the same  unresponsive  LEDs on  status,   and still wont play or respond to controls.  the LED 's  almost all on is  very abnormal.
.   this is very odd--  [ the polaris has replacement  membrane switch panels]  --  i have no idea what is going on.at this time-- ive had it for years  and this has never happenned.
