I hook up a drum machine or synth. in this case the boss dr-880 drum machine. sent 16th notes at 140 bpm to it from logic out one of the channels. recorded about 3 bars worth in. then i would load the wav file i loaded into wavelab, then i would get rid of the space at the begining put the begining of the first sample at 0.

Now, simply write down where each sample begins super zoomed in.

here is what i got on my test:

0, 108, 215, 322, 429, 537, 644, 751, 858, 956 etc etc etc… each number is the beginning of a sample.

Now, subtract like this. 215 subtracted by 108 = 107, 322 subtracted by 215 = 107, 429 subtracted by 322 = 107. etc etc.

no you see how its the same number, later on i get an 108, but thats it, i only got 107 and 108. a 1ms difference in time between each on average. That is how i did this test. Thanks to mr Todd Loomis for devising the test…

So if you want to test your midi, do so.

With my macbook pr, logic 8 express, amt8, fireface 800, i get 1ms of midi jitter on this test.
