Jymm

Nothing's happening, the midibox continues working, without rebooting or powering off.

Sometimes, I power off the midibox, and some other times, I let it powered, but results are the same, Stryd. David, when I plug J2, nothing happens on the LCD, it continues working properly.

No, I use Mike's kit. But Don't you think there coulb be a problem with the buttons or the encoders if ther was a problem between J1 and J2 ?

Let's say you're right Stryd, but which wiring do you I have to check ? DIN ? DOUT? Cables to the LEDS ? All of these are ok when I plug them separatly and when I swap them. It's not my LED cables because when I plug my 2nd group of leds on the 1st DOUT, they are all right ! I know it's not the DOUT cards for the same reasons: all the led light well when I plug them. I've just finished new cables between the cards, and the problem is still there. I did another test: I have a group of LED telling me the active bank. The first LED is lit, and I got 2DIN plugged. I try only plugging a connector on the J2 port of the 2nd DIN, and the led goes out, all the others then have the problem, they light two by two, or they don't light. Of course, I tried this with the three of my DIN cards and the results are the same.

Just a post to add that I launched the 2 test applications mentioned by DavidBanner. The results are the same: When I don't plug the last DIN, everything is ok. If I plug the last DIN card, there are some problems in the LED order from the 5th DOUT shift register.

Hi all, thanks for your help. I don't think this is a shortcut. I'm going to be more precise for the problem. I did other checks today and these are the results. But first, my config: 1core, 1Ain, 3Din, 2Dout, 1LTC 1st DIN: 30 buttons and 1 enc (for menu navigation) 2nd DIN: 32 buttons 3rd DIN 16 encoders All encoders are well defined in mios table. For the LED, I configured the Mk syx to have this, corresponding to what I want LED_SR1 = 2 LED_SR2 = 3 LED_SR3 = 4 LED_SR4 = 5 LED_SR5 = 6 LED_SR6 = 7 LED_SR7 = 8 LED_SR8 = 10 These are the tests: - All the DIN plugged and full: all is working fine (buttons and encoders) - Each DIN individually and swapped with another one works fine - All the DIN + 1 DOUT full: All is OK, in the good order - All the DIN + 2 DOUT (full or empty): problem with the second DOUT card (whatever card I use) - 2DIN + 2DOUT (all fully plugged): everything is ok. So I think that the cards are OK, otherwise I would have some problems when I swap them. But, I'm a beginner with C programmation, and It's possible that I have not configured a thing. Thanks for the help.

I didn't launch any test application. My power supply is a 9v 1000mA. I tried a few cables, and I know it's not the cables too.

I already switched the DINs, that's why I know they all work fine. Each DIN separatly works fine, and any combination of 2 of them work fine, but when I add the 3rd, problem with the LEDs, but, the encoders on the 3rd DIN work fine !

Hi Everyone, I'm finishing my mb64e, and I have a problem: I have 3 DIN and 2 DOUT. Everything is well soldered, I checked everything and all is ok. The problem is that when I plug 2DIN, all the LED are working fine. When I plug the 3rd DIN, either if no entry is connected, All the LEDs go off, and when I push some butons on other DINs, the LEDS seamed to be "shortened", some of them are on at the same time, 2 or 3 LEDs at time. Do you have ideas ? Thanks

Hello, I haven't got any problems an more. I have e-burnt the bootloader, reloaded the mios and the MB64e application, and I modified 2 solders which go to the A-B-C pins of the AIN module. Thanks for the help, my MB64e is now working fine.

I think I know the source of the problem. It seems that all multiplexers are working well, and the cables are good. The thing is that the faders (non motorised) are working as encoders, and are sending two values each time I move them. For exemple, when I move up the 5th fader, I sends CC1 channel 16 and CC1 channel 5. Do you know how to configure faders as faders and no encoders ? I think it should solve the problem.

Ok I found the cables, and I inverted A and C, and nothing changes.

Thanks Stryd one, but I don't understant where I can find these adress lines. Can you help me more ? It seems to be in a good way.

Hi, I tried your tips, and I checked everything, my solders and cables. The encoder problem is solved. My problem with faders is still there. I did an other test: I connected 8 more faders to the 2nd multiplexer of my Ain card, and it's terrible: I have the same problem. I mean that faders 1-4 don't respond, 5-8 respond well, then 9-12 don't respond, and 13-16 respond, really strange ! So I really don't think it comes from a hardware, but from my programmation. Any ideas ?

Thank for the answers. About the encoders, I will check that tomorrow. For the moment, I know they're working as Detended, but I will try non detended. For the faders, the first 4 don't do nothing, whereas the last 4 send values. I add that I tried to plug them directly on the port J5 of the core module, and everything worked fine (the 8 faders), so I think y solders are fine. I also plugged them on the 2nd multiplexer, and I had the same problem. I inverted the faders too, and the problem is still there. I'm quite sure there's a parameter to change, but I don't know which one (I'm a beginner with the midibox concept). Thanks.
