  Do you have the midi or non-midi version? The expansion boards are totally different. Check pin 2 of IC 6 and follow the track: R20 is located between Gate in and out jacks. R21 is near IC 6. One of the SDS6 here has R20 cut off and R21 lowered to 5K6. 
  Works with any trigger.

  Best

    so i looked inside the sds 6 and there's a lot of modification going on...

    i attached a picture of that section of board.  and the scheme.

    there's no R20 and R21 is routed to C14. but i don't see C14 on my scheme.

    maybe it's the one behind IC6?

    thanks in advance

    Check R 21 and R 20 on the expansion board, the 
    level is set there. To rise R 20 value to 1M or simply cut it away should do the 
    trick.

    (tom) trigger output, it seems to have enough juice to drive the SDS6 even 
    though the voltages are theoretically wrong. The SDS6 sync inputs (tape and 
    trigger) are very fussy, I think they need a bit of current drive rather than 
    just a certain voltage level. Always reminded me of 80's computers with 
    cassette loading where you spent ages trying to get the level just right.
