Hi All.

I'm having major headaches here........ Whenever I try to render anything done with live v4.0.4 with cubase sx 3 the results are intermittent...... I've tried every avenue i can think of, but alas to no avail.......... Can anybody help mejavascript:emoticon(':?')
Confused

Hi chitlun,

I'm not sure if I understand you... do you render something in Cubase with Live running as ReWire slave to Cubase?

regards,
Alex

Hi Alex.
The problem is arising when I'm running live as a rewire slave. When I come to do a mixdown the audio from live is intermittent. This seems only to have come about since I upgraded to SX 3. This as you can imagine is a problem for the final mix.

Hi chitlun,

the ReWire protocol does not contain information if the audio data pressing is done in real-time (normal playing) or not real-time (rendering, bouncing).
So when Live runs as ReWire slave it behaves like all data is processed in real-time. This again can lead to problem when you do a not-real-time operation in the ReWire host (like Rendering in Cubase SX in your case).

So the safest workaround would be to record your mix in real time in Cubase SX.

I have the exact same problem with SX2

huhh????

so why does SX export work with reason as slave for instance ?

Hi Chris J,

so why does SX export work with reason as slave for instance ?

I do not know if it always works with Reason. Maybe because a typical Reason song does contain much less audio files (unless you use a Sampler instances there) as a typical Live set.

But however, in Live when you use "Render to Disk" it handles the reading of audio files different as when normal playing in real-time. This should guarantee that all needed audio data is read timely enough. So without this information it can happen that some audio files are not read timely enough .
So the question is, does activating the "real-time" check box in the "Audio mixdown" dialog of Cubase SX solve this problem or not.

Maybe Propellerheads had a different (or maybe better) mechanism so that they do not need to separate between real-time and not real-time processing, I simply do not know.

When I use reason in rewire I actually use the NNXT sampler, many instances.

When I got this problem in live as rewire I was using just one loop (8 bar long) nothing else, no plugins , effects.

Hi Chris J,

as I wrote before, I do not know what Propellerheads do inside Reason.
Maybe a better mechanism, maybe NNXT sampler holds the clips in RAM,...

Let us see if the Mixdown in real-time makes a difference or not.

Alex

I'll try but even if it does that won't be much helpful as i never export in real time as I always have a lot of processing to be calculated

EDIT : I got confused here, for some reason I thought real time was going faster.

Nice one Alex.... The real time option does the trick. This is good, it means I can go and put the kettle on when it's doing its thing.....
Cheers you've been a great help
