SDK Question clbkConsumeDirectKey

[gattispilot]

So I have this:

int LER2016::clbkConsumeBufferedKey(DWORD key, bool down, char *kstate) {
    // only process keydown events
    if (!down) return 0;

    

        if (key == OAPI_KEY_1) {    // rotate- 
            RevertDD0();
            return 1;
        }
        if (key == OAPI_KEY_2) {    // rotate- 
            RevertDD1();
            return 1;
        }
        if (key == OAPI_KEY_NUMPAD8) {    // rotate- 
            TURN_STATE = 1;
            return 1;
        }
        if (key == OAPI_KEY_3) {    // WHEELLOCK
            if (WHEELLOCK == 0) WHEELLOCK = 1;
            else WHEELLOCK = 0;
            return 1;
        }
        if (key == OAPI_KEY_V) {
            SelectCockpitView(CAM);
            CAM = CAM + 1;
            if (CAM > 4) CAM = 0;
            return 1;
        }
        if (key == OAPI_KEY_J) {
            RevertSSCREEN();
            return 1;
        }
        if (key == OAPI_KEY_E)
        {
            SeparateMMU();

        }
        if (key == OAPI_KEY_7)
        {
            if (lighton == 0) lighton = 1;
            else lighton = 0;
            return 1;
        }
    return 0;
}
int LER2016::clbkConsumeDirectKey(char *kstate) {

//    if (!firstTimestepDone) return 0;

    
     if (KEYDOWN(kstate, OAPI_KEY_SUBTRACT)) {
        //pEngine->DecreaseTgtSpeed(down);
         { FORWARDgear = 0;
         REVERSEgear = 1;
         neutralgear = 0;
         LASTGEAR = 0;
         LASTGEAR = 2;
            double dv = 0.001;
            targetSpeed = (targetSpeed + dv);
            if (targetSpeed <0) targetSpeed = 0;
            //SetAnimation(anim_SPEEDCONTROL, targetSpeed);
            //decreaseTgtSpeed = down;
            //increaseTgtSpeed = false;
        }
        return 0;
    }
    else if  (KEYDOWN(kstate, OAPI_KEY_ADD)) {
        FORWARDgear = 1;
        REVERSEgear = 0;
        neutralgear = 0;
        LASTGEAR = 0;
        double dv = 0.001;
        LASTGEAR = 1;
        targetSpeed = (targetSpeed + dv);
        if (targetSpeed > MAXSPEED) targetSpeed = MAXSPEED;
        return 0;
    }
    else if (KEYDOWN(kstate, OAPI_KEY_NUMPAD5)) {//brake
        neutralgear = 1;
        targetSpeed = (targetSpeed - 0.1);
        if (targetSpeed <0) targetSpeed = 0;
//        FORWARDgear = 0;
//        REVERSEgear = 0;
//        neutralgear = 1;
        
    return 0;
    }
    
    if (KEYDOWN(kstate, OAPI_KEY_NUMPAD7)) { // turns wheels left
        ROTATELEFT();
        RESETKEY(kstate, OAPI_KEY_NUMPAD7);
    }
    if (KEYDOWN(kstate, OAPI_KEY_NUMPAD9)) { // turns wheel right
        ROTATERIGHT();
        RESETKEY(kstate, OOAPI_KEY_NUMPAD9);
    }
    FORWARDgear = 0;
    REVERSEgear = 0;
    neutralgear = 1;
    targetSpeed = (targetSpeed - 0.001);
    if (targetSpeed <0) targetSpeed = 0;
    return 0;
}

But when I hold the ADD key down the numpad 7/9 does nothing. When I release the add they work
