John,

sorry had no time to reply to your earlier e-mail. I noticed that
the rounding in (musmon.c, sensevents() ) seems to be the problem.

  tval = p->curTime + (0.51 * p->curTime_inc);
        if (p->frstoff->offtim <= tval){
            csound->Message(csound, "curtime: %f\n", p->curTime); /* I added
this to check the time*/
            timexpire(p, tval);
 }

you see tval is set to 1.750 at time1.749887:

curtime: 1.500000
B  1.250 ..  1.500 T  1.500 TT  1.500 M:  14142.1  14142.1
curtime: 1.749887
B  1.500 ..  1.750 T  1.750 TT  1.750 M:  14142.1  14142.1


and this is exactly when we get the glitch. But I was not able to find
a fix.

That was last week. I did not have time to progress on this, but
I think the musmon code is where we should look.

Victor
