I have updated and calibrate the Hihat.
Better feeling to play, more accurate... BUT
Yesterday evening, after four or five songs with the band, the Hihat started to do random sounds, double triggering (the band tought it was me...)
and open sound when close..... totally unpredictable!
I have done another Hihat calibration, all was good for three or four songs, and then... Random sounds again!!!!
I really plan to play on stage with this fantastic drum... but for now, impossible! I don't want this happening on stage!
