  1. D-Sub 25 output question

    Hello Having two separate planes mean distinction ! If you see it this way no system at all have distinctive 0V ref... as all finally end to the same safety earth point Connecting only one 0v will make ether digital or analogue return path through the other circuit, may not be trouble as you experienced, but it's easy to avoid this and make it fine at start, it's just one more wire... So I still recommand to hook TWO 0V wire, one hooked do DOUT pcb for D signal and one connected to AOUT (analogue side) PCB for CV signal. Best Zam
  2. D-Sub 25 output question

    Hello Tim It depend what is at the other side of the connector... I guess you better separate analogue and digital reference, at least. Best Zam
  3. is the STM32F4 EOL?

    Hi all For info I just check STM32F4disco at one of my regular component supplier, and there is a new one coming soon. So I check at manufacturer and the board is now NRND, replaced by something looking absolutely the same but with STM32F407VG in place of STM32F407VE. http://www.st.com/web/catalog/tools/FM116/SC959/SS1532/PF252419 I have no knowledge for understanding/comparison about change. Just to let you know there is certainly a need to check what's going on, and be sure MIOS/MBHP will run fine with new STM32F4 board Best Zam
  4. PCBs for sale

    Already ??? Best Zam
  5. Zener... with all respect... I start thinking you are just a troll here ... TWO page with ppl gently responding to you, trying to help. You still complaining whatever we say. As others, I'm out of this topic. Hope I'll see you in another one with REAL midibox in your hand. Best Zam  
  6. midibox Dj controller

    Hello I just have a quick look at your ngc (hard to read without text reformatting...) You have some led fwd without led definition also multiple event (same hw_id) with same id For your problem what I suspect is that your button 23/24 have a radio group (2) with respectively range 3 and 4, there is chance that at start the radio group 2 will have value 1 by default. Maybe just try value=3 at EVENT_BUTTON    id=502    hw_id=23 Best Zam    
  7. Problème pour programmer un module MF_NG

    Bonjour L'ampi-op va vite fumer si c'est pour piloter un moteur... Cordialement Zam

    Happy new year to all. Wishing everybody a lot of good things Best Zam  
  9. Dj controler

    Bonjour Cela dépend quelle stratégie est utilisée pour activer/passer d'un set de bouton à l'autre, bank ? radio group? Dans .NGC avec value= il est possible de définir l'état de départ d'un EVENT Dans .NGR avec set/change event (section 0) il est aussi possible de définir un état au démarrage Cordialement Zam   ps: le forum en anglais est plus actif...
  10. Encoders / Switches debouncing

    Hello Jerome I just let you know if you miss it, MIOS have debounce handled at soft side. Best Zam
  11. Hello That's a nice first post ! Bravo Zam
  12. DOUT with pro tools

    Yes should be possible, certainly different options, with conditional at NGC, or set_active at NGR. However you have to think it a little further as you may have domino effect with the mute function if you just do a basic logic You have to define situation you don't want the flash without locking the mute LED for simultaneous state you need a mute... Best Zam  
  13. DOUT with pro tools

    For button, Sysex trick only one way, MIOS can send it but not receive it. For led, all them triggered by value (on/off with formatting) and activated only if zone value match Best Zam

    Ok, here it is.

  15. DOUT with pro tools

    Hello 2hb I guess you try to set all this in HUI mode (which is not sysex !! ) I have an beta/optional NGC/NGR version for a control surface in HUI mode. I'll check it and share the code strategy for this purpose asap, it's tricky... Best Zam
  16. Hello Good ! that will for sure simplify a lot the conversion to Midibox IO side note, I'm interested to see the PCB assembly to front panel ! Best Zam
  17. hello It should work. and if led/button are in a daughter PCB at frontpanel It should not be that difficult. Best Zam  
  18. To me 140mA make more sense for BAx bulb or 14mA which is low but in the range for T5.5 bulb... Also 14A is not in the common range for most DMM... @2hb can you confirm your A meter setting? mA or A ? Best Zam
  19. Hello  14A ??? are you sure of that ? it's about 170W Please give use the ref of your light bulb to ensure no measurement mistake at your side. As Latigid say, no IC will help you here, you better use a power relay Best Zam
  20. Problems with OLEDs over time

    Yes... IIRC you already have issue with your LEDs before with AD chips Seems that those RGB led strip introduce LOT of noise all around. So careful design seem requested ? maybe a topic alone about this can be open, to share and set good practice for designer that introduce RGB leds, which seem to become more and more used by various members now. Best Zam
  21. Fatar 61 key keybed controller question:

    Hello Tedy I don't have the answer to your specific question, BUT there is no need at this forum to post 4 time the same question in different sub section... Best Zam
  22. Problems with OLEDs over time

    hello The Juno is now closed (with an audio IN mod)  but here I find pict (faster to me to google search than opening the enclosure, take pictures, and upload it ...) http://studiorepair.com/gallery/Roland/Juno-60/slides/Roland_Juno-60_Opened_Right__STUDIOREPAIR_09101301_1009108175.html you'll see the voice/cpu board with silver foil behind, the PSU have L plate that also serve as disipator for regulator there is also a foil at left hand bender board. Best Zam
  23. SeqV4/AOUT_NG calibration procedure

    Hello You may have an issue or faulty channel because it's seem out of the DA spec ?!? Best Zam
  24. Problems with OLEDs over time

    Hello I don't say that, I say wood is used as aesthetic over metal case or with extended metal foil screen. For example I service and mod a Juno 60 yesterday, the bottom/structural panel is plywood, with pcb attached on him, there is adhesive Al foil all around   It will also protect for EMI/RFI !! Both way, our lovely midi box can be noisy at digital lines (I learn it the hard way with my build close to discrete audio circuit) as catching perturbation from over populated electronic environment these days (computer, SMPS, all box in our room with digital electronic) Also you say you have 3 DC-DC converter in your build, still 150khz switcher. The one you show is open frame, maybe a screen around them can help too...   Best Zam
  25. again.. I don't get your point here, MB_NG is so easy, there is no C involved for setup...   You can't ask for deep access in a system and in the mean time asking no work at your side to handle it. MB_NG have mostly every things you can think about without any effort...  by the time you'll use it and find limitation, you'll be able to code in C   Best Zam
