  17. MB808 - i havent Trigger output

    in MIDIbox SEQ

    Posted

    Pulses are very short (only 1 mS) - did you consider this?

    Yes i understand that is very short

    how do you do to see the instrument trigger  led blinking withe the full MB808 ?

    I m thinking that i could see the pulse with an oscilloscope no ?

    I wanted to check if i have the pulse could you tell me how i can do it ?

     

     

    Menu Page Selection

    Perhaps i don't understand how it's work ...

  18. MB808 - i havent Trigger output

    I have some questions about the trigger section in the MB808

     

    i have keep the original configuration in the the asm files with the MIDI output port value = 1 like this

    When i try to check the DOUT with oscilloscope i don't see anny voltage .

    IT is normal or i need to do something ?

     

     

    ; Following table allows you to define
    ;   - the track names (must consist of exactly 6 characters!)
    ;   - the DOUT shift registers (SR) to which the drum triggers are connected
    ;     (1-16; 0 disables assignment)
    ;   - the DOUT pin to which the drum triggers are connected (0-7)
    ;     Note: since version v1.3 the "real" Dx pin number (D0..D7) has to be specified, in previous releases it was mirrored!
    ;   - the MIDI output port (0=disabled, 1=Default, 2=Internal, 3=IIC1, 4=IIC2, 5=IIC3, 6=IIC4, 7=Trigger Only)
    ;   - the AOUT/CV channel to output velocity (1-16, 0=disabled)
    ;     Note: AOUT module only supports 8 highres channels, but CV outputs can also be realized with DOUTs (see DEFAULT_CV_DOUT* option)

    I also read that about the Menu Page Selection but i can't change the value of manual page?

     

     

     

    Manual: If sequencer playing: position of all tracks will be set to the selected step.
    Sequencer not playing: triggers the step of the selected instrument

     

  21. MB SEQ V4 and led

    Posted · Edited by zephyrin

    I have used the file it's seem better but not ok i m suspecting that the mapping is not ok.

    Are you sure that is the last file?

    I m using the PCB from smash TV

    How i can have schematic ?

     

    Edit : 

    Now i m shure that my PCB don't work with the mapping in the MBSEQ_HW.V4 but i don't know why

     

    I m using the latest programn and and hwcfg file : V4_077

    i see in a other forum that U7 is on the back of PCB, on my PCB U7 is on the front face as the other . 

    it is possible that the mapping is doing for U7 on the back side of PCB ?

    Hi Duggle thank you for your answer. In my case all the led shine when the mb seq start. But some led shine low and other shine hight.

    I m not shure but i think is no good that all led shine at start ?

    The dual led shine low and the two color shine in the same time.

    So i think all the led is ok i will check again.

     

    do you need a special files in SD Card?

    Hello

    I think that i have a trouble with the Led of MB seq v4.

    I have used the wilba PCB . 

    I m using Blue led and dual led blue and red.

    For the resistor i m using 1kohm  for blue abd 470 ohm for the red.

    when i m starting the MBseq the blue led bright some less. 

    For the dual led the 2 color are on

    Some led bright and other are off.

     

     
     
    the same without SD card
