Wouldn't the seq round to the nearest match?  Seems
the most logical way they would handle it.

It's been a while since I did that test but from what I remember
I was able to get a perfect match with Cubase at many of the settings 
aavailable in the mpc3k.  

That was cubase audio 2.0 at the time, I belive it was 384ppq.

Thats interesting.  The first time I've seen a variation.
Now whether or not this was intended or merley a timing
thing would depend on how they captured the data.
From what I remember the mpc can export a midi file. This
would take away the timing errors and just give you what
the sequencer was trying to play.

If a midi file could be exported we would know for sure.

Do you happen to have a mpc3k lying around?

I should try taking some midi files from the mp-7 along
with recording the midi out of my sp1200 and compare.  Too
bad the sp1200 only does 8th note swing.  I could jack up
the tempo I guess on the mp-7 clock.  But on this last track
I did I used the mp-7 to actually play the midi to control a
shaker and tamp in the sp1200 and the swing was nice.

I'll have to dig out the mpc grooves for cubase and look at them
again as well.

But I totaly agree that the resolution will make a difference.
I just never thought that the swing itself was doing anything
different as far as intentionally moving some notes more than others.
From my experments it seemed like there wasnt any variation going on 
with any of the swing settings from different devices.

Would be nice if we chould store some custom groove settings in the 
mp-7 though....

Thanks for the info.
