audible timing difference when recording audiotracks?

Hi

I am sampling my evolver synth back into the MPC1k but it seems to me when I play back the audio track the timing is not quite what I am sampling. I am setting up some very specific feels using the evolver delays and somewhere i am losing the groove, I am not sure if it is moving the sample backwards or forwards... it sound early rather than late but I am not sure

If I play the sample back with the original there is a clear and significant difference in timing - note i am not talking about drum hits here but bass sounds so I think the difference must be more than a few milliseconds to be audible

I am trying to shift the loop back and forward a little bit to find the exact place but this is driving me nuts - trying to recreate something that was there to begin with... and failing actually?

I can think of a couple of reasons:

maybe what i am hearing is just the speed it takes the AD converters to convert the sound when recording? Maybe someone knows the speed of the converters and the number of ticks i need to adjust for this? or is the MPC1k missing some samples from the beginning evrytime it records and then effectively playing the sample too early?


am using latest jj os 4.98

are you playing the evolver from and mpc midi track then recording it in?
or are you slaved to an external sequencer?

when you record a midi instrument make sure all other tracks are off.
also midi channel 1 is tighter.

generally midi is not tight and never plays exactly the same twice.

not sure if this will help - i'll have a look into this - i record guitar and don't seem to be getting these timing problems. i'll check out some midi.

Yep as far as I know, they still don't sync up properly. There still seems to be a delay at the start of the audio track. Can anyone confirm this or know exactly what's going on?

On a slightly unrelated note, does anyone know why when resampling the main outs on 0dB master output, there is sometimes (alot of) clipping? It makes no god damn sense!

MO2: this clipping might be a result of inaudible clippings which occur sometimes. they sum up and your audio material will clips.
avoid this by increasing your masterlevel to -6dB.

if you want to visualize these clippings on your daw got to
http://www.solid-state-logic.com/news/X-ISM.html

this plug will show you the max level you can achieve without
reachingthe cliplevel.

and its for free.

default setting for master volume is -12db this is a kind of catch all volume safety.
if your doing heavy beat stuff with all the samples normalised and every thing louder than everything else vibe.

lighter more moderate volume d tracks -6db

more atmos, minimal beats, you may have to up the output to 0db to get a better gain structure.

The midi spec (supposedly) gives priority to lower channels.


Yeah, I think the audio track timing delay has been reported on here before. I get it too. Too bad. Could be a really nice feature and I'm sure I'd use it a helluva lot more if it wasn't for that. We all would. Does it work any better in OS2?

kinda dum really, that the industry chose channel 10 for GM drums.

sorry - don't know if the timing is better in OS2 have mainly been recording guitar - not done any external midi - audio.
