  2. Keyboard matrix 5 octaves, velocity, only 12+11 wires. Need a help please!

    in Testing/Troubleshooting

    Posted

    Dear Thorsten

    I have a keyboard matrix 5 octaves, velocity.

    I would like to connect it with core module, but I don`t know how.

    In the project "DIN Velocity UnMuxed" you said

    "Note that this application is not able to scan a keyboard matrix, but it could be useful to realize some simple drumpads"

    I have a hand draw scheme, but I do something wrong and you cannot see it. :-X

    (when I put the shortcut /home/qb/Desktop/1.jpg between insert image points the result is bad ; Linux FC4)

    So how to use keyboard matrix with core module?

    There are 2 connectors :  IN 12 wires and OUT 11 wires.

    Each key from bottom has 2 switches (sensor with gum), and 2 diodes (1N4  148  or IN4 I48)

    C1  : signal from 1 wire IN go to 1diode , next to 1 switch and next to 1 OUT wire

    C1  : signal from 2 wire IN go to 2diode , next to 2 switch and next to 1 OUT wire

    C1# : signal from 3 wire IN go to 3diode , next to 1 switch and next to 1 OUT wire

    C1# : signal from 4 wire IN go to 4diode , next to 2 switch and next to 1 OUT wire

    D1  : signal from 5 wire IN go to 5diode , next to 1 switch and next to 1 OUT wire

    F1# : signal from 1 wire IN go to 13diode , next to 1 switch and next to 2 OUT wire

    F1# : signal from 2 wire IN go to 14diode , next to 2 switch and next to 2 OUT wire

    G1  : signal from 3 wire IN go to 15diode , next to 1 switch and next to 2 OUT wire

    G1  : signal from 4 wire IN go to 16diode , next to 2 switch and next to 2 OUT wire

    G1# : signal from 5 wire IN go to 17diode , next to 1 switch and next to 2 OUT wire

    G1# : signal from 6 wire IN go to 18diode , next to 2 switch and next to 2 OUT wire

    A1  : signal from 7 wire IN go to 19diode , next to 1 switch and next to 2 OUT wire

    A1  : signal from 8 wire IN go to 20diode , next to 2 switch and next to 2 OUT wire

    B1  : signal from 10 wire IN go to 22diode , next to 2 switch and next to 2 OUT wire

    H1  : signal from 11 wire IN go to 23diode , next to 1 switch and next to 2 OUT wire

    H1  : signal from 12 wire IN go to 24diode , next to 2 switch and next to 2 OUT wire

    C2  : signal from 1 wire IN go to 25diode , next to 1 switch and next to 3 OUT wire

    C2  : signal from 2 wire IN go to 26diode , next to 2 switch and next to 3 OUT wire

    C2# : signal from 3 wire IN go to 27diode , next to 1 switch and next to 3 OUT wire

    C2# : signal from 4 wire IN go to 28diode , next to 2 switch and next to 3 OUT wire

    D2  : signal from 5 wire IN go to 29diode , next to 1 switch and next to 3 OUT wire

    D2  : signal from 6 wire IN go to 30diode , next to 2 switch and next to 3 OUT wire

    . . . . . . . . . . . . ..  . . . . . . . . . ..

    F5# : signal from 1 wire IN go to 109diode , next to 1 switch and next to 10 OUT wire

    C6  : signal from 2 wire IN go to 122diode , next to 2 switch and next to 3 OUT wire

    In worse case I`ll sctch a board and separate each switch IN (from only 12 to 122  :-\),

    connect all OUT "groundes" togetcher and use 4 DIN4 modules.

    But is this to possible to use orginal matrix, for free DIN for additional switches, encoders?

    How about latency ?

    Thank you T.K.

  4. Q about meters on lcd in a MBLC 1.6

    in MIDIbox HUIs

    Posted

    Hello TK

    Sorry  I`m very late with the answer:

    in  midibox_lc_v2_0_alpha1.zip  everything with meters on lcd works great.

    My late is because I`m try to write the assembler code for catch sysex .

    (I`m talking about idea ; not about details)

    So - if  I  will not  do this I will ask on the Forum .

    I don`t wonna  waste your time if I can try learn assembler . :P

    with greetings

    HELLO THORSTEN KLOSE!

    MAYBE IT IS A STUPID QUESTION  ???

    I CANNOT UNDERSTAND WHY WHEN I SET IN    main.asm      UNDER        General Aplication Settings  :

    #define INITIAL_DISPLAY_PAGE      3

    OR

    #define INITIAL_DISPLAY_PAGE      1

    FOR TAKE A METERS ON LCD .  In MBLC v.1.5  - METERS RUNS (WORKING)

                                                                IN MBLC v.1.6 - METERS ON LCD  not working  ???

    THANK YOU FOR RESPONSE

  8. how to recive sysex and save in 24lc512 - without midi-ox dump session..

    in MIOS programming (Assembler)

    Posted

    Hi good people  I have some questions:

    1    how to KEEP in ram 2048 values for store in 24lc512 eeprom?

          If one core with MIOS 1.8  can handle in range of memory  0x010-0x37f  (496 variables) what is best solution  for keep 2048 values:

          -build 5 cores linked (every keep about 410 variables) or

          -connect additional ram for increase range of free memory  (how???)

        maybe is better solution ???

        I would like after my session with music simply save this 2048 values in eeprom 24lc512 (my snapshot ;D)

     

    2.      What are possibilities  for store in 24lc512 eeprom  4031 bytes of sysex on the fly without manual recive dump in midi-ox?

    THANKS  A LOT  AND I WISH YOU HAPPYNESS  (FOR ALL MIDIBOXES MANIACS 8))

    Spoko - zach?cam, bo warto.

    Ja lec? ju? z trzecim sterownikiem z 48- ma enkoderami  i 4 -ma ekranami.

    Niestety narazie bujam si? z kartonowym panelem , ale przymiezam sie do wykonania panelu za pomoca pily wlosowej i sklejki.

    siema siema

    oczywi?cie najpierw  mios_bootstrap_loader_v1_1b    w  ICPROG.

    potem  mios_v1_7  poprzez MIDI  w MIDI-OX.

    i ju? mo?na dalej po sysexie jecha? inne programy.

    dodam ?e potencjometry za 3 PLN s? s??be (chyba ?e masz naprawde lekko chodz?ce w tej cenie)

    a za te same pieni?dze mo?na mie? enkodery  - no nie alpsa ale dzia?aj?ce poprawnie.

    ja u?y?em p?ytek uiniwersalnych ale ju? wiem ?e to pora?ka - zw?aszcza gdy przenosimy nasze modu?y z jednej obudowy do drugiej szukaj?c tej naljlepszej.  no có? nie ma to jak szybki efekt

    powodzenia

    Hi everybody!

    As first:    Thank You Thorsten Klose !!!!!!!!

    (good man gave us a key for realization our dreams):)

    O.K.

    I have finished my MIDIBOX in 3 mounth!!!!

    (with litle change code)

    If somebody looking for help in Poland  I`m still here.
