  1. What transistors do you use, the originals 2SA733, 2SC945 or the

    Halucinogen replacements (BC640, BC639)?

    And what Op Amps?

    Thanks

    hi sebo

    i used bc639/640 ((also for noise part)) and tl072 for opamp

    everything work well

    but i want to remake one my self and drawn everything

    and put all the pot on the board with voice because its so boring to solder all wire

    between pot and ci.  >:(   more than 200wire  :o :'(              (""i hate do that""))

    i gona make one board with all voice on it

    And a second board with seq,ctrl,...

  2. ive my 4 voice808 (bd,sn,ma,clp)now finished

    no one part was hard to find for me, i ve put the same transistor everywhere (npn,pnp ofcourse)

    and its sound good.

    ive just notice that all the hallucinogen mods

    are not working perfectly , because some pots dont work on

    100% some one are only active during 15% of the rotation.

    would be maby great to redrawn all the schematics

    and make it tcheked by some one That know well

    The "TWIN-T filter :)

  3. for now i was planning to  just build 4 sounds modul

    bass drum, snare,maracas & clap

    with midio128 to trig it in midi, without velocity

    i ve never think to build it with 4 output with different velocity on each

    good idea  :D

    i ll do it later.

    But i would like later build a complet tr808 with all sound, sequencer, 24ppqn sync etc ...

    lot of work :p

    i ll post sample of the 4sound808 when it s done , think will finish it tomorow

    ::) ::) ::) ::) ::) ::) ::) ::) ::) ::) ::) :P

  4. yes

    you re right , the answer was there !!!

    just needed to replace a part of main code

    USER_SR_Service_Finish

    clrf    MIOS_PARAMETER1     

    movlw  0x00   

    call    MIOS_DOUT_SRSet   

    movlw  0x01   

    call    MIOS_DOUT_SRSet   

    movlw  0x02   

    call    MIOS_DOUT_SRSet   

    return

    Perfect 1ms Pulse output ,  ;D YAhaaaaaaa!!!!!! :D

  5. ok, sorry !

    i m building a midi triger interface for a 808clone.

    i ve simpify the more i can the core modul , so i ve remove lcd connector and all

    route that was not needed, in fact i ve just keep the midi, and the dout.

    i ve upload midio128 without problem now, the problem was that the upload have to be done under 2 sec.

    now it s ok ,  but like all the time , i ve got a another probleme!!!

    the crystal dont seem to oscillate anymore!!!

    i supose that one of the 2 pin must be HIGH (5v)  and the other Get the 10MHZ

    But no one is HIGH, is it normal ???? maby is it i dont know

    i tcheked all pin of the pic with oscillo, no one is moving, ((( Its not a hardware problem , because

    with a another pic already programed for sid , the crystal oscillate and all pin Are dancing)))

    so ..... ?????? i dont know ? if it s normal

  6. yheap

    you re probably right!

    i ll do like this finally

    But i wanted to understand how work the famous TwinT Filter

    and see it in work by my eyes  ::)

    i just hope that there is no error in his pcb

    because without the schems it s not easy to understand

    :p

    but i think now , i would be able to do it with all the lecons of electronic that ive folow.

    i ll finish this , and find a other think, maby for my end of study work.

    ...i ll send this 808x clone's picture here later

    see you soon  :) ...

  7. hi

    i m also trying to make a clone of the 808

    i want to build eatch sound separatly on a pcb like Hallu.

    and build a sequencer. i gona use a R8c/13 µC From Rensas

    actualy i ve done only the basscick pcb and the switch board

    and i m working on the serial shiftregister, first time that i do a such complex

    work.

    i also simulate all sound modul with ElectronicWorkbench That is work pretty well for That

    maby it would Be great to cooperate.
