Thanks David, I used the deviation from the perfect grid but I think I did it wrong. Your method seems fine... though for me jitter is deviation from something that it should be, not from the last measured value.

These are objective matters, but it is undeniable that MD MKII has this same push-pull pattern as the MKI.

So, nothing new under the sun, I'm afraid

Ok, here's my question on this to Dave and anyone who feels comfortable answering. (note: I see why this type of thread can cause an uproar, and I'd love to discuss it elsewhere but...here goes anyway)
If there is a problem with timing from the main sequencer of a rig (again not pointing a finger or trying to stir emotion), and there is a slight drift in the sync. As long as there is no issue with the other modules that are being triggered, won't everything drift together. In other words, would the the units being controlled by a drifting sync, stay in sync with the drift?
I hope that's an understandable question.

peace

OK - in brief - imagine you have a precision reference pulse click track running at 120 BPM that has zero drift/jitter and you can slave everything off this (like word clock for audio). Unlike Word Clock however, most/all sequencer tempo/event scheduling and event triggering is under complex internal CPU/procesor control and is never fully slaved to the master tempo sync source. What this means is that CPU and DSP processing takes priority over incoming sync so that, long-term (over the length of a song) you get average tempo synchronisation between master and slave but short term (individual event sync) - you get push/pull slop - this is because at that level you reach the limit of the tempo precision of each individual device. It doesn't matter how tight the reference master sync is the slave will always play tag - rushing and dragging based on it's own processing limitations.

Hope that helps - regards - David

Understood!
Thank you Dave, I appreciate your test work and appreciate that you have offered a way to test machines, and that you welcome others to challenge your findings and method. If I find differently I will let you know and what is cool is that I know that that is welcome. Ego is no place for successful learning, music, life ect.

Pleasure omriL - I've not registered with gearslutz so I can't reply or post as yet (I'll get there) but the 808 litmus was tested/ slaved off a very tight (+/- 1 sample accurate) reference Din Sync master device. I felt this was more useful in the long run because most users run them as slaves these days in their setups. I'm going to borrow one and do the test again for the internal results - remember of course that (like the CR-8000) and other vintage sequencers that use analogue Multivibrator/Oscillator design for tempo generation - the internal tempo is only as acurate as the stability of the oscillator and the potentiometer that controls the rate. At least with external sync you have the capacity to overide this limitation to a degree if you have a reliable tight clock source.

Regards and respect - David

Where's the original timing thread?

The URL given above...does not work. And the search engine here doesn't either.

Dunno. Would have to PM Innerlock.

it does work. its just not capable of intelligent filtering or advanced search.
