  1. okay thank you

     

    ive been testing the switches....they give a beep if i put my meter on them  A-A gives a beep and B-B gives a beep

    and A-B gives a beep when switch is pressed......

     

    one other thing ive noticed......with my own seqv4 the step led lites up green when i turn the encoder....with this board the led does not light up when i turn the encoder

    so that is weird

     


  2. hi Peter

    thank you for helpling me (again you are my forum hero !!!)....but even with the schematic i can not find it.

    hoping you can help me a little more....this is what ive cheked so far:

    if i put my meter in beep mode and have one pin on the bottom left pin of Step switch 5 and the other pin on U2 pin 11....then i get a beep if i press the switch

    the same goes for step switch 6 bottom left pin to U2 pin 12 ...also gives a beep.....

    so this should be good right ?

    ive also replaced the duo color leds and also both 1n4148 diodes...but it did not help

    what other things can i check ?

     

    with kind regards,

    Vincent

  3. ok traced them down to U2...and that side is okay....but still can not find the fault.....are the switches connected to a groundplane or something ?

    because he ripped off some solder pads

     


  4. hi people

    im hoping someone can shine a light on this problem im having with a midibox seq4

    it has the wilba control surface (its not the new seqv4+)

    stepswitches 5 & 6 are not working (the guy who owns it tried to replace them...but he really did a grimm job soldering

    i cant really see where the traces are going and to what ic these two switches connect (it can probably be fixed with a wire but i need to know to what ic and pin they are going)

     

    any help is welcome,

    cheers

  5. hi there thank you it was indeed the jumper on the transmitter....now i have power on the aout board cv, gates and clocks are working !!

    another question i have is : is it possilbe to also connect the (old) TPD ?

    in my seqv4 i had it after the doutx4..... but now i see there is something different in the hw file (the option to choose the midiphy tpd)

    now TPD enabled 3 is set...and normally with the seqv4....TPD 2 would be set......would it even be possible to connect the old TPD?

  6. my setup now is : seqv4+ with new lindriver transmitter but on the other end i have the old linedriver receiver

    that might be the problem

    aout-ng is powered from my eurorack +12 and -12 volt and it needs power from the sirio chain (i think)

     

     


  7. hey there....im trying to get my aout-ng gates and clocks working....

    ive set the shift registers in the hw file (10 and 11) but no gates clocks and no cv...also the power led on the aout-ng does not light up with the seqv4+

    (and it does light up with my seqv4)

    tips are welcome....

    cheers

    Vincent


  8. thanks ...that makes sense

    ive followed up on the link....and set the shift registers but still no cv gate or clock

    also the led on the Aout-ng does nog light up when i connect the seqv4+ (and it does light up when i connect the seqv4)

    so i think there is no power over the 25 pin cable ?..

     

    cheers

    Vincent


  9. hi there...ive build the seq v4+  but now i can not get the CV (from Aout-ng) and GATES and CLOCKS (from dout board) working

    i have the (new) linedriver transmitter inside the seqV4+ and i have the (old) lindriver receiver on the other end of the cable

    i have a Aout-ng board and a doutx4 connected to the receiver (clocks, gates and cv were working on my (old) seqv4...now im trying to get this working with my new seqv4+

    what ive tried:

    inspect the linedriver module

    set the si jumper on the lindriver transmitter (it is there on my old seqv4)

    set the correct Aout board in the menu

    ive tried to assign the shiftregisters to the same numbers and pins in the hw-file as i did with my old seqv4....but this gives only messed up leds.

     

    can some one help me with this ?

     

     


  10. hello

    ive got some older midibox stuff that i do not use anymore.

    maybe somebody stil has some use for it

    1x pic based core

    1x lpc based core (with seqv4 software)

    2x din R5 board

    1x PIC PROGRAMMER (with printerport connector and power supply)

     

    1x pic18F4520

    1x pic18F4620

    1x pic18F4685

    2x panelset (front and back panel for the TPD track position display

    3x LCD display

     

    selling the whole lot in one go for ....20 euro


  11. i have really tried it but i could not get it to work .....everything works but not the BPM and STEP digits

    can you help me on how to set up the numbers ???.....so i can see what i did wrong here

    ive got it working now with the dout at the end.... but the build doc sugests to put the TPD at the end of the chain.

     

    cheers

  12. Hi there

    can someone help me with the assignment of shiftregisters in the HW file ?

    my setup is as follows....midibox seqv4 wilba control surface....linedriver transmitter to linedriver receiver....the Aout-ng for CV out ...then one Dout board for 8x gates and 8x clocks then the TPD module

    ive got both led matrixxes and the encoder working correct....but the segment displays for BPM and STEP dont work...

    ive tried different shifregister settings...and if i put the wilba-tpd hw file on the sd card...it works fine...but then i dont have gates and triggers

     

    help is welcome !

    cheers

    Vincent


  13. ive got the strangest thing...

    i have three boards..one is a older discovery board witch is in my midibox SEQV4

    the two other are new one from mouser (STM32F407G-DISC1) they are programmed with the same bootloader and latest seqv4 0.91 software.....the older works fine but the new ones do not work...

    the problem is ....

    when i power it from the micro usb...it does not show anything in the displays...but when i it power from the mini usb ...it does work

    (the core board with the cardreader are both the same and work fine).

     

    what can this be ?
