Hi, I'm finishing my MB-6582 and can't find where I messed up. Encoders work, LEDs work, buttons work but don't do what they should do. Third bottom button for example makes third horizontal LED line blink, and LED's go on and of everywhere every time I push a button (LCD menu also changes) Encoders work fine. With the matrix test every LED lights up except the Control Env LED. When I push buttons nothing happens en the LCD. No shorts on the U20, 5V on the pins coming from JD5 and 10kOhm to 5V on every pin. I have not used the BC547 transistors and have bridged across. But that should work, right? Will be great full for any insights! Cheers FC
first of all: thanks to TK for all your great work!! so i finally got a seq v4 and soldered everything yesterday. i got a MBHP_CORE_STM32F4, Wilba SEQ CS board and MBHP_MIDI_IO. i used the wilba MBSEQ_HW.V4 file without any changes and the newest firmware version (088) no magic smoke after the first power up, but not all the buttons are working. only step 6,7, 10 ,11 of the step buttons are working and some of the other buttons also do nothing. (i didnt check which ones exactly, because i am unfamiliar with the user interface and never sure if every button should do something in the menu page i am in) the encoders all work fine. i didn't solder the leds yet, because the panel is not ready and it will be easier to get them in the right position if i do them later. i did check the solder joints visually and the orientation of the ics on the CS Pcb -no obvious problems there. my roommate also build a unit for himself and we sourced all the parts together. his unit has the exact same problem. thats why i think it is not a simple solder error like a short or wrong orientation of some part. (because that would be unlikely to happen twice.) please help me with troubleshooting. i don't really know where to start looking. i am a midibox noob by the way. (only did a seqv4lite in the past) so it is probably a noob mistake...
