Hi i finaly found where is the problem. I have change the two 74HC595 and now it s seem to be ok I think that one of the 2 74HC595 have not ok .

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 i think it's the problems but can't download the file with mac os and windows 7 too.

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

Thank you for your answer Thorsten. I don't have the doug's or moogha PCB, i have make the keyboad with vero board so the key are not at the same place. Also i have used the 3 microlarge PCB with full mod and i have more pot than you. I will try to contact Richard for know if he can help me

Hello I wanted to know if some one have a Schaeffer files for the front panel of MB808 . Thank you Zephyrin

Hi Thorsten i have the 3 PCB : baseboard, percboard and voiceboard http://xlargex.xl.funpic.de/projects/808/docs/808_baseboard_v1.0.pdf http://xlargex.xl.funpic.de/projects/808/docs/808_percboard_v1.0.pdf http://xlargex.xl.funpic.de/projects/808/docs/808_vioceboard_v1.0.pdf

I wanted to know how connecting the 808 microlarge PCB with the MB808 On the microlarge PCB for BD i have 2 pin TR and AC but i don't know where take the ground.

Thorsten, it's correct that the a,b,c,d,e,f,g and dot connection is sahred (the same) for the 3 displays and only cathode (or anode ) are separate ?

Thank you Thorsten, Can i used D3 D4 D5 ect ... of the DEFAULT_BPM_DIGITS_COMMON DOUT for led ( for exemple for Beat, Recod and live switch) If yes, i need to used resistor for the D3 D4 D5 ect ... ?

i have bought some led Digit display like this http://www.lenoo.com/ec99/myyp090083/GoodsDescr.asp?category_id=51&parent_id=0&prod_id=2066 I wanted to konw how connecting The 3 DIGT on the DOUT.

I have resolve the probleme, i was a trouble with dupond connector ... For the final, i think that i will soldering cable on the DIN and Dout model for minimize Dupont connector.

The LEDs are enabled regardless of the selected page. I have build the A B C D Led and is the same. For information i haven't build the bankstick. I use the setup_808_default, i have just changhe the DIN section for remapping the switches. The Switches work well. I m supposing that i have activity when the sequencer playing because i see the date in the MIOS Studio, the data stop if i m sopping the sequencer with stop switch. But the LED don't change...

I have try to make the 16 led (GP L and R ) but they are always all on, it is normal ?

Thank you, i have change the mapping for the switches and it's work.

Hello i wanted to change the switch and led mapping. I have see the notes in the setup_808_default.asm file and i supposed that i will make the change in thi file. So i think i need to build a new HEX file after make the change ? If yes how i can do this ?

Hi think for your answer Peter. I just look quickly the source, i think it's not so easy. i m suspect that the BPM is just calculate with only 3 digits.

Hello I wanted to know if i can used BPM Display 7 segments with 4 digits with the MB808 as the MBSEQ V4 ?

There are a circuit triggers on the 9090 over J30 DATA and J31 CTRL (just only 10 wire) , i don't know how it's work but someone are using J30 DATA and J31 CTRL here for building the sequencer of his 9090 without used midi MR9090 I think it's J30 and J31? Jozef only use midi. The MB9090 use only 8 74HC595, i m supposed that we can add some other 74HC595 via (DOUT) for triggering the 9090 boards via J30 and J31
