  1. I know there are a lot of posts about this already, but I have gone through the troubleshooting guide and am still left with some confusion as to whether I am doing everything right.  I am getting 5v everywhere on the mf_ng module. I've tried 3 different midi interfaces. a "usb uno" , presonus firestudio project, and rme raydat  I have tried programming a pic18f452 and pic18f4523 using the pickit3 and the pickit3 software which is running in parallels. according to the the pickit3 software, the bootstrap upload has been successful, but I still can't connect to mios.   When testing the grounds on the capacitors connected to the crystal i get 4.97v on one leg of either capacitor. I'm not sure if that is normal or not. But both capacitors get 5v on one leg.  The crystal I am using is from Reichelt when I connect the pic into the socket on the module, I only get 3.23v on pin 14 of the pic, pin 12 is getting 4.97v (with the positive terminal of the multimeter connected to Vd of J2, and the negative terminal connected to the pic pins and capacitors) I've tried all the midi loopback tests and they have all been succesful 3.23v on pin 14 doesn't seem right to me. Maybe that is the problem? I'm not sure how to fix that though if it is I included some screenshots of the pic programming. The bit values are all default, do I need to change those at all?

    They usually operate somewhere around 170volts so it is definitely something to be extremely cautious with. It is a separate high voltage power supply connected to the anode,  the cathodes are all connected to the 74141 or K1551d1 like Antichambre said, the 74141 is connected to a 74HC595, a dout module ! I've never seen THX 1138, i should watch and try and spot them!  For the coding, I would have to use the template for logic control for pro tools. I'm just not sure exactly how to forward the mtc digits to send on/off messages to the dout's outputs I've tried to forward the timecode values to a single led just as a test, but I don't know how to implement it properly. or if this is even the right direction. I tried from this section, which uses a sysex stream:

    I'm not sure I know how to answer, but it seems like the common method is to connect the nixie to a sn74141 or similar, with 4 connections ultimately, to the arduino. here is a diagram for what seems like the most simple way to do it     from this page: http://www.instructables.com/id/How-to-Control-a-Nixie-Tube-with-an-Arduino/ the arduino sends basically a 4 digit binary value to the ic that corresponds for each number, 0 through 9, in the nixie. So I am thinking maybe, if it is possible to connect this to a dout module, that the mtc digits could somehow be programmed to send this 4 digit code instead of the 7 segment values. possibly with senders and receivers?

    How would you go about setting up a nixie display for Midi timecode? I know there are drivers and boards available online for interfacing nixie tubes with arduinos. I am thinking if I used that to connect to a dout module, then maybe it would just be a matter of coding? Has anyone tried doing this?
  5. DOUT with pro tools

    Thank you!! It is all working now!  I guess as a side note, do you think there could be a way to make the mutes not flash when you solo a channel? 
  6. DOUT with pro tools

    I'm having trouble getting leds to work properly with pro tools At the moment I have the leds responding when I press solo in pro tools, but the problem is, when I press solo on any channel it will turn on all leds I have assigned. I know that the problem is in the way I'm coding because it is only doing this in pro tools. The code I am using is this, which are the cc equivalent values to sysex zone select/port on: EVENT_LED id=  1 type=cc chn=1 cc=12 range=0:0 EVENT_LED id=  1 type=cc chn=1 cc=44 range=67:67 I can't get them to respond with sysex messages, whereas it does work for buttons. For example, this was not working: EVENT_LED id= 1  type=sysex stream="0xb0 0x0c 0x00 0xb0 0x2c 0x43" I have the buttons configured in a similar way as shown before with cc messages with ranges and they work, so I thought maybe this could work for the leds, but it appears that is wrong What would be the right way to do this?     
  7. I'd be glad to share, there are two pcbs on either side, connected with a ribbon cable on top All of the modules I have are the same model sl506, but are all configured differently it seems, they all have these different mods on the outsides of the pcb On this one, the same "ic4" I posted earlier has a sticker with the word "Film" on it. They are from a 5000 series which i know were meant more for broadcast and post production. so maybe this was more formatted for film?  Another interesting thing is the two extra buttons at the bottom. The sl506 doesn't have two bottom buttons on the front panel, but other 5k series faders do, so manufacturing-wise they didn't omit the switches based on the fader model, just the fader caps. There are even the leds inside, I know because I applied power to them and they lit up ! I'm guessing that later, they would make modifications by hand based on how the customer wanted their console configured, but it is all a mystery to me really Also sorry about the quality, I can try to take some better pictures, I just have the camera on my phone
  8. Hello! Yes exactly, eao switches, connected to a small pcb on the bottom, that is where i've been powering them, with the incandescents under the button cap  That's what I meant to say, replace the incandescents with leds, i didn't know that was possible ! I feel silly now, I am very new to this sort of thing, I wasn't sure it would be so easy to interchange them They are just situated in a way inside the switch that seemed impossible to get out without a special tool, they are only 3mm, so t1 size? It is really hard to find t1 remover tools I tried using a precision flathead screwdriver to remove them and sure enough I broke some in the process, but I ended up just using a piece of electrical tape to remove all of them !  I just tested with a 3mm led in place, so now I just have to connect to a dout module. So I'll be using leds now with the dout as is. it's better that I keep things as simple as possible .. Thank you Zam! You help me once again And even though i'm not using the incandescents I still appreciate everyones help!! I very much appreciate this forum and midibox in general This is my first project so you'll probably be hearing more from me
  9. here is a link to the manual for the fader module: https://mega.nz/#!8h1mgAaQ!TcjGyKONf1by4TnP1rBjYrE4w2c1744TLIW995_6qvw  
  10. I should be more clear on that, my idea was the latter, each fader module has a number of switches and leds, and in this case two incandescents, which were originally used for vca automation. I wasn't planning on powering the modules, I was thinking just to basically bypass the whole circuit and access the switches and lights directly to use solely as a controller.  ep320pc-2 is the part number for that ic http://www.datasheets360.com/pdf/-3584855117084061587 The modules aren't really in the best shape, and I'm not sure if they are in complete working order (neither did the person I bought them from) 
  11. Okay, it was actually set for milliamps, so 14 mA not A, sorry for the misinformation! I am very new to this as you can probably tell The power supply i've been using is just a 12v adapter 1500mA output.  I would just use leds, but there doesn't seem to be an easy way to remove them from where they are installed without breaking them, they are for the afl pfl switches from an ssl fader module ! .. There's not really much information about what the actual ratings are for them, but I did manage to find them in this block diagram from the manual (top right): Hopefully this provides a little more information on them.  Thanks so much for the help!
  12. I'm not sure if i did this right, but I connected the positive from the 12v power supply to the bulb via a multimeter, and the ground of the bulb connected to the negative of the power supply, it read about 14A, would that be the correct way to do it? I haven't ordered the dout module yet, so it would be the r5 version so would the vs and ground of the 2981 connect to the power supply's positive and ground through the two extra holes on the pcb where the arrays normally go? and then resistors would connect to the outputs 1-8 on the 2981?      
  13. Thank you, I appreciate the help, so a 2981 after the 595, are you saying it would fit where the resistor arrays would normally go? How would I supply the secondary voltage?  
  14. Hello,  I was wondering if there was a way I could use a dout module to interface with incandescent bulbs that require more than 5v, I am not sure their exact voltage, somewhere around 12v. Would this be possible with an external power source somehow?
  15. DIN HUI Emulation help

    Hi Zam, Thank you so much! This makes a lot more sense, I have been trying to work off of the hui documentation to modify the template, but I didn't realize it uses CC messages, is there anything else I would need to change in logictrl.ngc other than the individual button events?
