I bought a used Grids today but it doesn’t seem to be working properly. Example:
Power on with nothing plugged in
Hold tap button until is stays on and the rhythm stops
Turn Map X knob all the way to the right and then back to the left
Observed: 1st 2 LEDs are flashing and the 3rd stays on
Expected: either all 3 on or all 3 off
Also, the rhythms sound really bad, and are nothing like what I hear on YouTube, and the kick pattern barely changes as I adjust E1, Map X and Map Y.
Is this indeed malfunctioning? And how do I fix it?
