it's different from measure to measure. 
maybe i have to explain it better. i was wondering how tight the 
timing of the md is. here's what i did.
i recorded the output of the md without any synchronisation in 
logic for 3 minute.
i used a pattern with just one bd sound every 1/4 note at 120.0 
bpm without swing or slide.
then i set the start point at one of the first bd beat in the audio file 
and adjusted the tempo in logic so that it matched one of the last 
bd beat. this resulted in a tempo of 119.9271.
then i checked if the beats  between were at the right position.
here's the deviation in samples from the absolute song position 
of consecutive bd beats (44 samples are a deviation of 1 ms):

position in song         deviation in samples
1.1        0          
1.2        -35
1.3        -38
1.4       +25
2.1        -43
2.2        -45
2.3       +48
2.4       +14
3.1        -20
3.2        -23
3.3       +39
3.4       +4
4.1        -30
4.2        -32
4.3        +29
4.4        -37
5.1         -8
5.2         -43
5.3         +19
5.4         -16
6.1         -18
6.2         +43
6.3         +9
6.4         -25

and so on. the max. deviations in this example are -45 and +48 
samples. so we have a deviation of +-1ms. 
i tried classic vs. extended mode and different machines with 
similar results. and this is not a problem of logic. logic is 
recording absolutely accurate.
i think this in not very tight for a drum machine.
