yo! i had a small break in buidling the SID box, but now back in business. 
i just had all the cables finished and so i was able to make more testing with the interface. so, here’s my problem: all the LEDs in the LED matrix are lit (except one, i think it’s more likely that i’ve connected it wrong rather than the led beign broken..) all the time. all buttos seem to be working ok i guess, as encoders too. other LEDs should be ok too, just the matrix stays on all the time. what might be the problem? i’ve checked the cabling and it should be right but obviously there’s something i’ve missed… they shouldnt get lit at all if they would be soldered the wrong way??
cheers
